Exide
EPA Challenges State Clean-Up of Frisco Smelter Waste
Despite denying that it was submitting comments on the state's plan for cleaning up the recently closed Exide lead smelter, the Environmental Protection Agency turned in a sometimes scathing assessment of Austin's proposal to allow the company to treat prohibited hazardous waste that still lies buried in its landfills in Frisco.
"The landfill is not permitted or constructed as a hazardous waste unit. Please clarify the regulatory/statutory provisions TCEQ is following that would allow for treatment of hazardous waste in the landfill," wrote EPA Associate Director Susan Spalding in a five-page letter sent to the Texas Com mission on Environmental Quality (TCEQ) on January 25th.
News of the Agency's comments comes on the eve of a public meeting scheduled by Exide for Wednesday night at the historic Frisco Depot to explain its clean-up operation.
Besides criticizing the on-site treatment of the hazardous waste, EPA also had a harsh review of the way Exide and TCEQ had identified areas of the current landfill with concentrated lead wastes that needed treatment, suggesting four times as much sampling as the company had proposed, and TCEQ had approved.
EPA also noted that a closed landfill in Frisco was already leaking hazardous levels of lead and selenium and suggested that the treatment method Exide is using in its current landfill was not going to be effective.
But in what may be a crushing blow to the company's plans to keep the wastes it generated for almost five decades buried in Frisco permanently, EPA stated that if the current landfill had been used for disposal after 2011 sampling to determine clean-up, which it almost certainly has,"This may require removal of all material" in the landfill.
Many of the problems cited by the Agency are the same ones citizens have been complaining about since Exide announced its unusual scheme to try to treat its illegal hazardous waste in place in its Frisco landfill, instead of digging it up and re-burying it in an official, licensed hazardous waste disposal site.
Exide does not have a permit to handle or dispose of hazardous waste. It's landfill is classified as a "non-hazardous waste" disposal site. The hazardous waste inside of it was discovered by inspectors several years ago.
Citizen groups have said Exide must apply for a full Resource Conservation and Recovery Act permit in order to deal with its prohibited wastes. EPA's letter seems to suggest that the Agency agrees.
Besides commenting on the landfill plans, EPA's letter also seeks changes in the dust controls guiding the smelter clean-up, and the public release of information about the clean-up.
Copies of the EPA letter can be downloaded from the Frisco Unleaded website here.
"We're very appreciative that EPA changed its mind and decided to comment on the ridiculous plans by Exide and TCEQ to use the same treatment method on this hazardous waste that failed to work the first time," said Colette McCadden, Chair of Frisco Unleaded, the citizens group who successfully campaigned to close the old smelter last year.
"We hope the EPA continues to provide needed oversight to what Exide and the state are doing – or not doing."
Other groups were more cautious.
"It's a pleasant surprise to see EPA comment so bluntly about the more absurd parts of the proposed Exide clean-up," said Jim Schermbeck of Downwinders at Risk. "My hope is that this is only the beginning of a new level of review for Exide by the Agency in light of the USA Today's "Ghost Factory" series chronicling what happens when it's not paying such attention. Only time will tell."
They’re Not Asking Your Permission
Exide and the State are planning Frisco's future without it's residents.
This Wednesday night may be one of the few times they can object in person.
Plans are proceeding for Exide to leave landfills full of its lead smelter waste in Frisco….forever
Landfills of lead on the edge of downtown that will pose a constant public health threat and economic dead zone
Landfills of lead along the banks of Stewart Creek as it flows downstream into the City's new "Grand Park"
Join us in saying no to their lead-filled future of Frisco.
Exide's Public Meeting on their lead smelter "Clean-up"
THIS WEDNESDAY NIGHT
7:00 pm
Frisco Depot
6499 Paige Street
(in the Historic District by Babe's)
Whether Frisco residents like it or not, Exide and the State of Texas are deciding to let millions of pounds of lead waste stay buried in Frisco forever – and the current City Council isn't trying to stop them.
While the city bought the less-contaminated outer ring of the Exide lead smelter, the most toxic part of the facility is still owned by Exide.
The City of Frisco has said that it won't interfere in the way the company and state decide to handle the tons of lead waste buried in this area, which stretches from Stewart Creek to the edge of downtown.
Exide, the state, and this city council are all deciding that it's easier just to leave lead contamination permanently buried in place in the middle of Frisco instead of moving it away from people and flowing water.
If citizens don't show up and fight back against these plans, Frisco residents will be dealing with lead contamination issues for decades – just like other communities that didn't have their lead smelter waste cleaned-up completely either.
A former Exide smelter site still sits abandoned in Dallas, some two decades after it closed, surrounded by monitoring wells and a chain link fence. We can't let that happen here.
Many residents sent e-mails to Exide last week saying they wanted a complete clean-up of its lead waste in Frisco. Now they need to come in person with the same message.
Frisco residents have to stand up for their home and community. Nobody at Exide or in government is.
Was Lead Contamination the Major Cause of 20th Century American Crime?
That's the hypothesis that Kevin Drum makes in the latest issue of Mother Jones, and he has a lot of evidence to back it up.
For years, scientists have known about the link between lead exposure in children and decreasing IQ levels. More recently, researchers have discovered more subtle effects in terms of anti-social behavior and AHHD diagnosis. Now, modern toxicology is to the point where most leading researchers say there is no level of lead a child can be exposed to that doesn't have the potential to effect his or her personality.
What if you were to use what we know now about the effects of lead contamination on young minds and playback the last 70 years of American history?
The biggest source of lead in the postwar era, it turns out, wasn't paint. It was leaded gasoline. And if you chart the rise and fall of atmospheric lead caused by the rise and fall of leaded gasoline consumption, you get a pretty simple upside-down U: Lead emissions from tailpipes rose steadily from the early '40s through the early '70s, nearly quadrupling over that period. Then, as unleaded gasoline began to replace leaded gasoline, emissions plummeted.
Gasoline lead may explain as much as 90 percent of the rise and fall of violent crime over the past half century.Intriguingly, violent crime rates followed the same upside-down U pattern. The only thing different was the time period: Crime rates rose dramatically in the '60s through the '80s, and then began dropping steadily starting in the early '90s. The two curves looked eerily identical, but were offset by about 20 years.
So Nevin dove in further, digging up detailed data on lead emissions and crime rates to see if the similarity of the curves was as good as it seemed. It turned out to be even better: In a 2000 paper (PDF) he concluded that if you add a lag time of 23 years, lead emissions from automobiles explain 90 percent of the variation in violent crime in America. Toddlers who ingested high levels of lead in the '40s and '50s really were more likely to become violent criminals in the '60s, '70s, and '80s.
Dr. Howard Mielke of Tulane, who's analyzed the blood lead data collected from Frisco and found the samples higher than the state average, makes an appearance in Drum's article because of a large new study overlaying neighborhood lead exposure to neighborhood crime in six American cities. They match up precisely.
Read the short version of the article here. Here's an interview with Dr. Mielke.
No one knew a lead additive in gasoline would produce such an impact. Because we didn't do the toxicology. Lead was introduced in gasoline in the 1920's when the modern industrial age was just hitting its stride. Now there are some 80,000 chemicals in the marketplace, only a handful of which have been tested thoroughly, including lead, because we're still not doing the toxicology BEFORE the chemical is used in widespread commerce.
Cancer. Birth Defects. Endocrine Disruptors. Why is it so inconceivable to some that the thousands of untested chemicals coursing through the veins of our economy can't have unintended consequences just like leaded gasoline, on their own or in combination with each other? What new epidemics are we instigating even now?
Public Health Action Alert – Exide’s “Community Meeting” on Wednesday
Please come and insist that the clean-up of the Exide lead smelter be open to public notice and comment, and not done behind closed doors.
Exide is hosting a hastily called "public meeting" on demolition and dust control plans for its former Frisco lead smelter Wednesday night beginning at 7 pm at the Frisco Depot in the Historical District, 6499 Paige Street.
Among other things, Exide wants to permanently leave a waste landfill in central Frisco with approximately nine million pounds of smelter waste inside, instead of trucking it out.
The city is letting the company have its way, even though this landfill in downtown will be an impediment to economic development and a constant threat to groundwater and air contamination that will demand never-ending monitoring.
All of the decisions about the clean-up of the smelter site are taking place behind closed doors with no public input or notice.
Last Friday the company submitted its plan for the permanent hazardous waste landfill and got it approved the very same day without any public notice or comment.
Wednesday's meeting is about a demolition plan that has already been written by the company without listening to any public concerns. They're only letting residents know about it after the fact.
We know it's the holiday season – that's why Exide scheduled this meeting. The company hopes you've quit paying attention. We hope you haven't.
There's a lot of dangerous material on the Exide site. If it's not disposed of correctly, Frisco could have an economic and public health black hole in the middle of town forever, what USA Today called lead "ghost factories." That's why this is important.
Meanwhile, the city of Frisco is protecting your interests by…being a silent partner to Exide's plans. City Hall has defaulted to the state and the company's judgment and isn't acting as an independent watchdog.
The City is writing press releases with Exide, but it isn't asking hard questions about the clean-up, or hiring its own experts to double-check what Exide and the state are proposing. It isn't demanding public notice or comment on behalf of residents. In fact, the city is keeping information about the clean-up and smelter to itself, refusing to post it online or release it to residents or reporters.
Come to the Wednesday night Exide meeting to express your displeasure with a strategy that's putting the same people responsible for creating the Exide mess in charge of "cleaning it up."
At this point we need the same public pressure that caused the city to change course and close the outlaw smelter to help open the closed doors that are hiding the clean-up process from public view.
Good Friday: Exide Smelter Closing Today
Sometimes, all it takes is the slightest push of an index finger, or a focused exhaling of breath.
Sometimes the house of cards is so precarious, so unstable, that any challenge, no matter how slight, can send the established structure to the ground.
A year ago a small, newly-formed citizens group that had just staged its first action was struggling to convince the City of Frisco to quit supporting co-existence with an outlaw lead smelter and instead kick it out of town.
Today, that smelter will stop operating.
Community activism rarely pays off as quickly or as spectacularly as it has with the curious case of the Exide lead smelter. But when it does, it's reason to pause and give thanks and remind ourselves that such things are still possible.
Because truth be told, this historic effort was directed by a group of Frisco residents that was never larger than 10 people strong. Please just think about that. Less than a dozen people challenging their local status quo are responsible for this huge victory for public health.
Downwinders' often tells its supporters that, like the Woody Allen quote about life, 90% of social change is about just showing up. The system so often goes completely unchallenged, that you'd often be surprised what happens when you just show up and start asking embarrassing questions. When you start poking at the house of cards.
As their campaign proceeded, this small group of committed people attracted the support of hundreds, and then thousands of their fellow residents. They forced the city to see the contradiction between the continued operation of a circa-1960's smelter and the reality of 2012 Frisco. They held up a mirror and re-framed the relationship between smelter and town. And the contradiction was so great, so at odds with the new perception of Frisco, that the established political support the smelter had enjoyed in town for decades dried up. Young couples with kids concerned about a lead smelter they never heard of before outnumbered Good Ol Boys in City Hall and the Chamber of Commerce. The old establishment was undone by the very demographics of change they'd unleashed a decade or so earlier.
There is still much work to do. A half-century of contamination blankets the smelter site, as well as an undetermined number of off-site "hotspots." Exide wants to leave a permanent landfill behind in the middle of Central Frisco, while the City is breezing along with plans to turn a piece of land right across the street from the smelter site into the city's largest park. Downwinders will be helping citizens monitor the cleaning-up of the smelter site for at least the next two years.
But as of today there is no more lead pollution coming out of the Exide smokestacks. No more daily fallout of poison. No more new layers of lead being laid down in the topsoil of Frisco. That is a pretty remarkable thing considering where we were 365 days ago.
So raise your glasses tonight to the hardy folks of Frisco Unleaded and the improbability of the impossible happening in record time. Here's to Colette McCadden, Henrik Ax, Shiby Matthew, Matt Vonderahe, Jeannette Sandin, Meghan Green, and Eileen Canavan, all residents who decided they would stick their neck out and start showing up and asking questions, much to the consternation of the Powers That Be. May they all have Frisco parks, and schools, and streets named after them.
It's not always this easy, but the fact that it was this time should give us hope about the power of pushing back.
Even Low-Level Cadmium Exposure in Womb Can Lead to Lower IQ
By way of the Environmental Health News comes word of a new study looking at the effects on low-level, "ambient" levels of the toxic metal Cadmium on 5 year-olds in Bangladesh.
Although the exposure pathway in the study assumes the Cadmium is coming primarily from a diet of food grown in contaminated soil, the results speak to the possible effects of any kind of risk – inhalation or ingestion.
"Prenatal exposures to the metal cadmium — even at low levels common in most countries — can have long-lasting effects on children's IQ. A study from Bangladesh found that 5-year-olds who were exposed through their mothers to higher levels had IQs that were 2 to 3 points lower than less-exposed children. The new evidence suggests that even low-level exposures before birth may have continued effects on children's brain function.On average, scores dropped by 2 to 3 points in children with the highest exposures when compared to those with the lowest exposures. Even small drops in IQ may affect a child’s ability to succeed at school and work later in life. Lower IQ's across the population also have large impacts on society."
Cadmium is a naturally-occurring metal contaminant found at low levels in the environment. Industry uses it to make batteries, coat and plate plastics and other metals, and make paint (remember Cadmium Red?). It's also emitted by car exhaust, the burning of industrial wastes, coal, and oil. When spread on fields, fertilizers and sewage sludge contaminated with cadmium can increase levels in cropland soils.
What are some possible local sources of cadmium in the air? The Midlothian cement plants that are now increasingly burning industrial wastes. Steel mills – like the Ameristeel one in Midlothian. Lead smelters like the one Exide is closing up at the end of the month in Frisco, along with the slag and battery chips the smelter "landfarmed" in Frisco for decades. These are all in addition to the Cadmium you may be ingesting through your diet or by sucking on that cute charm bracelet you bought that was made in China.
The Miracle of Our Perpetually-Projected Lady of the Public Hearing
In 2009, when there was an EPA national hearing in DFW on the then-proposed cement plant air pollution rules, the mood was festive. There was a brand new administration. There was a campaign for a brand new EPA regional chief from our own ranks gearing up. The brand new air pollution rules at the center of the hearing were capping a two-decade old fight to enforce the law. They were symbolic of a shift in momentum. Citizens had won. The event was held in a large hotel ballroom, and indeed, for citizens who had been a part of that fight, it felt like a day-long celebration.
Three years later, the party was over. The newness had worn off. A once "indefensible" Bush-era ozone standard that was going to be replaced, was instead adopted by the new administration. Dr. Al had won appointment, only to pummeled into resignation by a political mugging that left even the most cynical shaking their heads. Grim persistence was the most common trait shared among the citizens who faithfully trooped to Arlington City Hall for last Thursday's national EPA hearing, where those same rules were now under attack by the Agency itself. It may have only been three calendar years, but that ballroom scene seemed sepia-toned distant now.
Which makes the attendance at Thursday's hearing more remarkable in some ways than the large crowd that gathered in 2009. Then, clean air advocates occupied 88 out of around 93 or so speaker slots available for the all-day hearing. Last week, they occupied 83 out of 86 slots. The faithful were coming, but they weren't happy about it. Isn't that always the case in these stories? Right before the faithful are rewarded with a sign?
The first speaker of the day was young Andy O'Hare of the Portland Cement Association, who, despite being on what appears to be the winning side of this battle, didn't look like he was having a good time. He dutifully and stiffly read a prepared statement that took a pro-delay stance and applauded EPA for being reasonable, i.e. agreeing with the PCA. Justification for the delay was evidenced with the help of a laminated multi-colored poster of a seven-step explanation/timeline that he held up himself without aid of easel or stand. "This timeline," he said as his unsteady grasp floated the graphic on a sea of nervous energy, "reflected the fact that the industry had concluded without a doubt that it would need exactly two years to adapt to the rules. You just had to add up the steps." It looked enough like a high school science fair project at this point for you to wonder why this industry can't invest in better PR help. We're losing to these guys?
Except from some of the same kind of praise by the Texas Cement Council, and the obligatory "We don't even agree tighter standards are necessary" rhetoric from the Texas Association of Business representative, that was the extent of testimony in favor of EPA's last-minute rollback. No individual cement manufacturers spoke. Not even TXI, headquartered only about 20 miles away in Dallas. They must think they have it in the bag.
Following O'Hare, Downwinders Director Jim Schermbeck testified in the place of Downwinders' matriarch and founder Sue Pope. News came on Friday that doctors told the 72-year old Midlothian rancher that she needed a heart transplant. Everyone thought it was a good idea for her to sit the hearing out.
But Schermbeck didn't let that happen. Not exactly. Even before any testimony began, he projected a picture of Pope on a screen above the proceedings. She was staring down at Andy when he testified. Maybe that's what made him nervous.
"These are not industry's rules. These are not EPA's rules. They are Sue Pope's rules, and you shouldn't be messing with them," said Schermbeck. Tracing Pope's 25-year fight to reduce pollution in her hometown, he told the EPA panel she and a handful of others were actually responsible for the rules and it was now destroying them. "EPA has shat on everything Sue Pope has worked for with these proposed revisions, and it should be deeply, deeply, ashamed." He concluded his five minutes by feeding a letter-size version of the same picture of Pope that was being projected larger than life into the desk-size shredder that had been donated for the purpose of telling EPA what they were destroying with their rollback. Schermbeck said the proposed delay and revision was now destroying the woman herself.
Schermbeck wanted to leave that larger-than-life image of Sue up on the screen for as long as anyone in charge would allow. He wanted it to hang like a spectre over the entire day's proceedings. But he knew the screen saver feature on his computer powering the projection would eventually kick-in and make everything go dark. It always does. He's been doing presentations with this combination of equipment for years now and it always goes dark after 10-15 minutes. He'd forgotten to turn it off for this hearing, and now it was going to kick in any minute.
Only it didn't. He kept waiting and waiting. The screen saver never came on. A five-foot Sue Pope head remained there, hovering over the Council Chamber, with eyes as large as dinner plates looking down and directly at the EPA officials taking testimony (Howdy Keith Barnett!), all day long, all 10 hours. Sue Pope was the Alpha and Omega of the hearing.
It wasn't a piece of toast or a tree trunk. But through some unexplainable mix-up of electrons, a real true life saint did make an appearance at the EPA hearing. The official minutes won't reflect it, but for the faithful, the sign was clear: Never, never, never, never, never, never, never ever give up.
Under Ms.Pope's gaze, there was a long parade of poignant and moving testimonials, most finding different ways to say "hell no" five minutes at a time.
Clint Forsvall talked about the thousands of tons of Mercury the EPA's proposed delay would dump into the air, and why, as a parent of an autistic child, that was abhorrent to him. Midlothian resident Alexandra Allred spoke about how often she's had to take her son to the emergency room for middle-of-the-night asthma attacks.
The Galemore family from Chanute, Kansas came and educated everyone on what it's like to live in an isolated cement company town where hazardous waste is still being burned and where there's no independent media, or effective government oversight. Susan Falzone from Hudson, New York came and talked about the 100-year old history of cement plant pollution in that precious river valley. Kemp Burdette from Riverkeepers in North Carolina took on the proposed giant Titan plant. Stephanie Maddin from EarthJustice in DC spoke on behalf of those that couldn't make it to Arlington due to the ridiculous 11-day notice.
Local COPD victim Harriet Irby testified why every little big of air pollution reduction helps her in the daily chore of breathing. Arlington regular thorn-in-the-side-of industry Kim Feil was there with Ben Zene. Retired physician Dr. Robert Portman gave a primer on Particulate Matter pollution. Someone showed up at the last minute after hearing about it only that day to plead for less poisons in the air. It was, she said, important to her.
Most impressive was how so many people that had come to praise EPA in 2009 now came trudging back to try and do their part to keep the rules intact. These are people who know the power of persistence, even when it's in the cause of a rearguard action that shouldn't even be taking place.
Given EPA's transparent intent to steamroll the revisions into law, did we do any good at all? We don't know. But we did our job. EPA tried to make it impossible to get people to come and show their outrage. People, lots of people, came anyway. EPA may still go through with these senseless revisions, but they'll have to do it without a scintilla of public support. We robbed them of that fig leaf.
And we don't know about you, but we're taking the miracle of Our Perpetually-Projected Lady of the Public Hearing as a sign that, although it's highly unlikely that a woman with no technical training, no money, and no political support can, with the help of other similarly-deranged citizens, eventually bring an entire national industry kicking and screaming into the 21st Century…..it can happen.
Crohn’s Disease Linked to Lead Smelting Pollution
Ulcerative colitis and Crohn's Disease are similar debilitating diseases of the digestive system which can include symptoms like severe abdominal pain and diarrhea. About a million and a half people in the US have the condition, which many researchers now believe to be linked to environmental causes.
A Harvard Medical School study recently added to the evidence of such a link when it identified a cluster of suffers in extreme northern Washington state who live in proximity to an old lead and zinc smelter on the other side of the US-Canadian border. That smelter has been the source of complaints about pollution in the US as far back as the 1930's, when compensation for pollution damage was recommended by the Border Commission. Harvard doctors, including lead researcher Dr. Josh Korzenik, asked approximately 120 former and current residents of Northport, Washington to take a health survey. 17 of them had Ulcerative colitis or Crohn's.
“That’s about 10 to 15 times what we’d expect to see in a population the size of Northport,” said Korzenik, director of the Crohn’s and Colitis Center at Brigham and Women’s Hospital, one of Harvard Medical School’s teaching hospitals. “I’m not aware of any other cluster like it.”
But that could be because no one has looked. What kind of health survey logistics would it take to bring a similar study to Frisco, where emissions from the Exide lead smelter have been coating the surrounding areas for almost 50 years? Who would think that these symptoms could be linked to smelter emissions? Respiratory problems, IQ and developmental issues, even deafness, but not chronic stomach ailments. This is just one more disease that Frisco residents will have to try to determine if the Exide smelter is leaving behind as part of its toxic legacy.
Four Years Later, State Gets Around to Issuing Clean Air Plan for Exide That Won’t Apply
In 2008, the EPA issued a new lead-in-air standard for all U.S. lead smelters.
In 2011, the Texas Commission on Environmental Quality finaly submitted its first proposed plan to meet that new standard in Frisco, Texas, host of the Exide lead smelter. It was rejected as inadequate by EPA on the same day it was submitted.
In May of 2012, the City of Frisco and Exide reached a settlement that commits the company to ceasing the operation of its Frisco smelter on December 31st, 2012.
Last week, the Texas Commission On Environmental Quality released its second plan to meet the 2008 EPA lead-in-air standard at the Exide smelter in Frisco. Its effective date is December 31st, 2014, or two years after Exide will have closed per its agreement with the City of Frisco.
The plan and the accompanying Agreed Order doesn't incude any fines or enforcement measures that address the dozens of violations detailed by TCEQ inspectors at the Exide smelter just last year. Nor does it address the closure and adequate clean-up of the smelter once operations cease.
Between 2008 and the end of this year, Exide will have released an estimated 14,000-16,000 pounds of lead into the air in Frisco.
If you're thinking that this TCEQ planning document is irrelevant, you'd be pretty close to summarizing not only this episode, but decades of state oversight. And yes, this is why it's important to have citizens suing Exide themselves to enforce the law rather than Waiting for Godot TCEQ.
“How your great grandmother’s chemical exposures may affect you”
In a study published this week, "rats exposed in the womb to five common environmental pollutants passed on DNA-changing attributes that persisted in causing ovarian cancer three generation removed from the original exposure."
It's another example of "epigenetics" – when harmful environmental exposures to one generation can skip a generation or two and show up as health effects decades later.
According to the new study, the five pollutants reprogram how DNA is expressed in the developing fetus' eggs, setting the stage for ovarian disease later in their life.
If you're a Vet, the news is worse. The U.S. Department of Defense helped select the pollutants based on potential exposures in military personnel. They included vinclozolin, a fungicide that's used in the wine industry; a pesticide mixture including permethrin and DEET; a plastic mixture including bisphenol A (BPA) and two widely used phthalates (DEHP and DBP); the industrial byproduct dioxin; and a hydrocarbon mixture called "jet fuel," which is used to control dust on road surfaces.
Researchers at Washington State University exposed pregnant rats to one of five different chemicals alone or in mixtures during a critical time of pregnancy when their daughter pups' eggs were developing. The pups were then mated with males from the same treatment group, and the resulting pups were bred yet again. Only the original generation of pregnant rats had been exposed to the chemicals. The adult daughters and great granddaughters of the dosed animals (called the F1 and F3 generations) were examined for ovarian disease.
In all exposure groups, both the daughter (F1) and great-granddaughter (F3) mice had fewer egg follicles in their ovaries compared to controls, indicating a reduced pool of available eggs. Both generations – but particularly the F3 animals – also had an increased number of ovarian cysts compared to controls.These findings are characteristic of Polycystic Ovarian Syndrome (PCOS) and Premature Ovarian Insufficiency (POI), which are believed to affect 18% of all women.
Other diseases, including allergies and asthma; liver, gastric, prostate and colorectal cancer; and psychiatric disorders are thought to have an epigenetic component. This is the first time that epigenetic changes have been shown in association with ovarian disease. This proof-of-concept study used higher doses of chemicals than what people would typically encounter. Future work is needed to investigate whether lower, more environmentally relevant chemical levels also affect ovarian disease across generations of the rodents.
Locally, we're surrounded by sources of one or more of these pollutants, especially phthalates, BPA, dioxin, and hydrocarbons. BPA is the subject of a lot of media attention and just yesterday, the FDA banned its use in sippy cups for infants. Frisco's Exide lead smelter has been a top ten dioxin polluter in Texas over the last decade. The cement plants in Midlothian are also large industrial sources of dioxin, and new permits to burn more "non-hazardous" wastes that turn into hazardous emissions only ensure that will remain the case. On the ground, internal combustion engines from cars and the natural gas industry facilities in the Barnett Shale soak us in hydrocarbons.
Despite the documentation of the epigenetic effect of certain pollutants in recent years, this impact has not yet been incorporated into any risk assessment of a polluting facility by any environmental or public health agency in the U.S. We may be planting the seeds for epidemics of all kinds in the next 20-50 or more years, and it's all perfectly legal now. Once again, the science is way out in front of the regulations. That's why citizens must arm themselves with the latest research. You won't be getting updates on this stuff from EPA or TCEQ. That's also why it's ridiculous for anyone to speak about the "over-regulation" of polluters in this country. We're nowhere close to understanding what the long term consequences are of our actions in allowing so many chemicals into the environment to mix and match with our own biology. In this larger public health sense, pollution is still very much under-regulated in the United States.
