Prenatal exposure to high levels of air pollution double the likelihood of children becoming obese in a new study by Columbia University's School of Public Health released last week. Its one of the first reports to definitively link chemical pollutants to weight gain. Pregnant women who lived in areas where they were exposed to abnormal amounts of Poly Aromatic Hydrocarbons, or (PAHs), were more than twice as likely to have children who were obese by age seven than women who had lower exposure to the chemicals. PAH's are a pretty common pollutant which come mostly from the burning of fossil fuels. This news comes on the heels of a new study of the danger of chemicals known as endocrine disruptors, which can reek havoc with a person's hormones. Animal studies had already shown that PAHs inhibit the release of fat in the body, decrease IQ increase behavioral disorders. And oh yeah, PAHs can also give you cancer. There are many causes for weight gain in the US. Could one of them have anything to do with our swimming in a sea of 80,000 chemicals, only a handful of which are fully understood, much less regulated to reflect the current science?     Read More

Pregnant women who inhale air contaminated with chemicals called polycyclic aromatic hydrocarbons (PAHs) are more likely to have children who develop behavioral problems by the time they reach school age, according to a new study by the Children's Environmental Health at Columbia University's Mailman School of Public Health. The same group of researchers had previously linked exposure to PAHs with possible chromosomal damage and IQ loss. PAH's are organic chemicals that are less water soluble, and so less likely to evaporate, than other ingredients of particulate matter pollution, or soot, which they often hitch a ride on into your lungs. PAHs are produced from incomplete combustion of carbon-based fuels  - like any internal combustion engine or industrial boiler or furnace - and include acenaphthene, anthracene, benzo(a)pyrene, and fluorine. Their toxicity varies and depends on how the PAh's were made. Some are carcinogens, others mutagens, and some are completely non-toxic. The problem is your lungs don't have a filter to distinguish the bad ones from the benign ones.    Read More

Among the many faux EPA outrages Big Business and House Republicans have fostered upon us, you may remember the meme that the feds were going to put thousands of hospitals and school boilers out of business with super strict new emission rules. In fact, the facilities most affected by the rules weren't schools or hospitals. They were on-site chemical incinerators and boilers and of course, cement kilns. However, the pile of manure that was churned out enveloped the Agency and, as with the new ozone standards, made it retreat and reconsider the originally-proposed rules. Newly reconstituted, the Commercial and Industrial Solid Waste Incineration rules (CISWI) were dumped by the Administration last Friday at closing time like a late-night gangland victim at a hospital emergency room. After review, it's easy to understand why. The rules did not go far enough for industry, which would find any regulations onerous. And in an attempt to win the business community favor, the administration gave away strict standards for particulate matter, dioxin, and toxic heavy metals like lead and cadmium. Nothing was done to narrow the broad definitions of "nonhazardous solid waste" that allows for the burning of just about everything is it gets the right exemptions, including tires, plastics garbage, car interiors, and creosote-treated wood. This is where the entire industry is headed - the grey area of these nonhazardous solid wastes - as exemplified by TXI's "landfill in the sky" permit recently awarded by TCEQ to the company without any public notice or opportunity for comment.  And for the time being, this administrations seems happy to allow it.   Read More

A new study by members of the British Parliament who are organized into something called the Environmental Audit Committee concludes that 200,000 UK citizens die every year from breathing dirty air, which not only causes illness on its own, but exacerbates existing conditions. "Lewis Merdler, campaign manager at Environmental Protection UK, which leads the national Healthy Air Campaign, says air pollution in the UK has a huge impact on the nation’s respiratory and cardiovascular health, and particularly affects children and the elderly. 'Air pollution in the UK represents a huge public health crisis, contributing to more premature deaths than obesity and passive smoking combined,' he says. 'It’s a scandal the Government isn’t doing more to protect the most vulnerable in our communities from dangerous levels of air pollution.”  Read More

Twenty-two years ago, Congress deemed 200 kinds of chemical air pollution so toxic as to require strict enforcement and regulation of their release on a strict schedule in a speedy way. That hasn't happened. It hasn't happened in a spectacular, why-don't-we-all-have-jet-packs-yet kind of way. The Center for Public Integrity follows up last week's "Poisoned Places" collaboration with NPR with a great dissection of why the current system of regulating toxic threat is outdated and overwhelmed. It's the best argument for why new chemicals should be required to prove their benign effects up front - BEFORE they get released into the marketplace and we all become lab rats in someone else's experiment.   Read More

(Dallas)---- Only three years after it finally stopped the controversial practice of burning hazardous waste at its Midlothian cement plant, TXI was awarded a permit in June by the Texas Commission on Environmental Quality allowing the company to burn at least 12 new kinds of industrial wastes in its kiln without any public notice, comment, or hearing, and based only on other cement plants' data.  Read More

In trying to get the news out quickly about the four-part NPR/Center for Public Integrity series on toxic pollution in America titled "Poisoned Places," we didn't do a very good job of explaining the origin and purpose of the two different "watch lists" that the reporters discovered and publicized.  In fact, we're pretty sure we got it dead wrong. So here's a second try. There's a list that was begun by the Bush Administration in 2004 that included what the EPA considered "high priority violators" nationwide. As of September, this list was about 1600 names long. In North Texas, TXI, Holcim, Ash Grove, Exide, Magnablend, the GM plant, the Bell Helicopter plant, and over 100 other sites are included on this longer "high priority violator" list. There's a second, smaller "watch list" of 464 facility names of facilities nationwide with on-going violations, but which no administrative action has been taken to resolve. This is the list that only two North Texas sites are on - GE Engine in Ft. Worth and Ash Grove Cement in Midlothian.  National Map of the 1600 sites is here. State map of the Texas sites on the 1600 list is here.   Read More

Stung by criticism that it wasn't doing enough about cracking down on chronic polluters, and facing a tough re-election fight, the Bush Administration in 2004 established a secret "watch list" to help it identify the worst bad actors. If, after nine months of knowing about a critical environmental violation at a faclity, there still hadn't been any enforcement action, the facility took its place on the list. As of September of this year, that list had grown to 1,600 facilities. Thanks to NPR and the Center for Public Integrity, you can look at and investigate a map of the US identifying those 1600 plants, including over 100 in the DFW area when you use the Zoom tool the NPR website provides. Many names are familiar - TXI, Holcim, Ash Grove and the Ameristeel steel plant in Midltohian all make the list, as does the Exide lead smelter in Frisco, as does Magnablend, the Waxahachie plant that just blew up, as does places you might suspect like the GM plant in Arlington or the Bell plant in Ft. Worth, However, there are lots and lots of places that maybe you haven't suspected, like the Americhem plant in Mansfield, or Valley Solvents and Chemicals in North Ft. Worth. The sites on the list are rated 1 to 5 on a EPA "Risk Factor Scale," with 5 being the maximum risk. All of those sites we just listed are all rated at Risk Factor 5 - that is the combination and/or volume of chemicals released make them among the most dangerous sites on that "watch list." But wait, there's more. Within this larger watch list, there's a second, more selective list of REALLY bad actors that numbers 464. Almost 10% of those sites are in Texas, but only two are in DFW: GE Engine Services on FAA Blvd. in Ft. Worth and our good friends at Ash Grove Cement. You remember Ash Grove - the owners of the last obsolete wet kilns in Texas that refuse to modernize their cement plant just south of DFW. As we remarked on Monday when DFW officially replaced Houston as the "Smog Capital of Texas," DFW hasn't historically been associated with dirty air and dirty industries the way the Gulf Coast has been. Unfortunately, that's changing.   Read More
