Another Reason to Fear Hog Factories

Buried in this abstract from the Environmental Science and Technology Journal is a little titbit about the origin and fate of 90% of all natural estrogens found in water bodies.

Fate, Transport, and Biodegradation of Natural Estrogens in the Environment and Engineered Systems

Another major source, which accounts for 90% of the estrogen load, is animal manure from concentrated animal-feeding operations (CAFOs). Manure is not required to be treated in the United States as long as it is not discharged directly into water bodies. Thus, there is an urgent need to study the fate of animal-borne estrogens from these facilities into the environment. A number of studies have reported the feminization of male aquatic species in water bodies receiving the effluents from wastewater treatment plants (WWTPs) or surface runoff from fields amended with livestock manure and municipal biosolids.

I am not a big fan of hog factories. Clean them up!

  • Industry flacks to write new EPA rules

    Greater Role for Nonscientists in E.P.A. Pollution Decisions – New York Times

    The Environmental Protection Agency has changed the way it sets standards to control dangerous air pollutants like lead, ozone and tiny particles of soot, enhancing the role of the agency’s political appointees in scientific assessments and postponing the required review by independent scientific experts.

    Now let’s see which famous “Industry advocacy group” may be behind this one…

    The change, which largely tracks the suggestions of the American Petroleum Institute but also adopts some recommendations of the agency’s independent scientific advisers, was announced yesterday afternoon by the agency’s deputy administrator, Marcus Peacock. Mr. Peacock said it would streamline a cumbersome process and bring it “into the 21st century.”

    Ah, the 21st century, where scientists know nothing and it is best for groups that will gain most from a weakening of legislation actually write the rules. This way, there’s no pesky “scientist” using “knowledge” to shape policy, only rules written for the short term gain of a few.

    It gets worse

    For one thing, agency scientists will no longer produce their own independent review of the latest science to start the process of deciding whether a pollution standard — for lead, say, or ozone — is tough enough to protect public health. Instead, initial reviews will now involve both agency scientists and their political bosses and will produce a synopsis of “policy-relevant” science, agency officials said.

    “They are using this idea of streamlined and expedited decision-making as a Trojan horse to infect the most important decisions the administrator makes with politics,” Ms. Patton said.

    In addition, she said, the role of the independent panel of scientific advisers — who act as auditors, reviewing the document produced by agency scientists and advising top management — has been diminished. The panel, the Clean Air Scientific Advisory Committee, will now comment on the agency’s proposed actions after the public has been notified of them, giving the scientists essentially the same kind of participation as industry lobbyists and environmental groups.

    (Emphasis mine). And they wonder why morale at the EPA is low. There are hordes of good (not great, but good!) scientists at the EPA who spend all their lives working on each of their scientific niches, and to take away any decision making or policy input from them is dehumanizing their work. Wonder why the EPA has a lot of trouble attracting talent.

  • Trade Agreements Create Pollution Havens

    Interesting paper out of the Berkeley Global Economy Journal
    Trade Agreements and the Environment: An Industry Level Study for NAFTA
    Raymond MacDermott. Global Economy Journal Volume 6, Issue 3 2006 Article 3

    We find strong evidence of both the pollution-haven hypothesis and the positive impact of the NAFTA on FDI.  In addition, we find the trade agreement exacerbates the pollution-haven effect.  That is, the incentive to invest in countries with weak environmental regulations is greater under a trade agreement such as the NAFTA.  Surprisingly, stronger evidence of this effect is found in lower polluting industries than in higher polluting industries.

    Chemical agency ties under review – Los Angeles Times

    As I mentioned a couple of days back, Sciences International has some conflicts of interests in this bisphenol A issue. I am glad that NIEHS is taking note.

    Chemical agency ties under review – Los Angeles Times

    The National Institute of Environmental Health Sciences has begun a review of ties between a federal health center that evaluates the risks of chemicals to reproductive health and a consulting firm funded by companies that produce chemicals linked to reproductive disorders.

    The investigation follows a Times report on Sunday that Sciences International, an Alexandria, Va., firm funded by more than 50 industrial companies, helps manage the federal Center for the Evaluation of Risks to Human Reproduction.

    Among the firms with financial ties to Sciences International are two that produce bisphenol A, a chemical in polycarbonate plastic bottles that has been linked in animal testing to prostate and breast cancer and reduced fertility.

    Since 1998, Sciences International has helped manage the federal reproductive health center and prepared draft reports analyzing bisphenol A and 16 other chemicals. The company has a $5-million contract with the center.

    The center’s scientific advisory panel was scheduled to decide today whether bisphenol A endangers reproductive health in humans.

    But on Tuesday, director Michael Shelby announced that the panel, after two days of reviewing the 372-page report that Sciences International prepared on bisphenol A, known as BPA, still had too many unresolved questions and was postponing its decision for six weeks.

    Good investigative journalism still makes a big difference.

    As always, as I was writing this post, I noticed that the ever excellent folks at the pump handle read my mind and posted about it (2nd time in 3 days!), so I will stop writing (and thinking about Bisphenol A) and direct your attention to their post!

    Coffee Roasting and Popcorn Lung

    Cross-posted from Interrobang

    Who among us coffee drinkers don’t love the smell of freshly roasted coffee? I am sure some of us imagine how much fun it would be to smell freshly roasting coffee more often. I don’t, because smell for me is an instant jolt of pleasure/pain followed by a rather rapid decline into the background.

    Caution, though. New measurements from the US Centres for Disease Control warn of high exposure to some pretty nasty chemicals that can cause your lungs to be destroyed irreversibly, the unfortunately named “popcorn lung” or bronchitis obliterans:

    Investigators with the National Institute of Occupational Safety and Health, a research arm of the CDC, spent several days at Madison-based Just Coffee in July. Investigators tested personal air space and took air samples to measure the concentration of the chemicals diacetyl and 2,3-pentanedione… NIOSH researchers found levels in three breathing-zone samples that exceeded the safety levels recommended by the CDC.

    Coffee Roasting Plants and Exposure

    The test results show a marginal exceedance in this case, but noted that ventilation is a big factor and these tests were done under well ventilated conditions on a warm and dry day when doors were open. So, exposure can be higher in other circumstances.

    Worker exposures are to higher levels, and are more sustained, so they deserve the most attention.

    So, local coffee roasters, it may make sense to confirm that your roasting environments are not exposing your workers to harmful, lung obliterating chemicals. Remember, organic, shade grown, fair pay, artisanal roasting aside, chemical exposures to workers don’t change. And, everything that smells good isn’t good for you.

    One of my frequent points of emphasis (rants, some might say) is on the relative risk vs. media attention to exposures of people to ambient, day to day concentrations of potential harmful chemicals vs. those faced by workers everywhere. The last time diacetyl and bronchitis obliterans were in the news, it was around the use of diacetyl to produce that buttery smell so beloved in microwave bag popcorn (I don’t like it myself, olive oil all the way!). Despite reports of many workers facing severe lung issues, it took the detection of the disease of one person eating multiple bags of microwave popcorn over many years to actually move government regulators into action on diacetyl. People who work in factories, in the fields, and make things are exposed to thousands of times higher concentrations of harmful chemicals for longer periods of time, but their concerns are often de-emphasized.

    This doesn’t mean ambient exposures in the general population are to be ignored, but worker exposures are to higher levels, and more sustained, so they deserve the most attention.

    16-May-2016 Update

    This US Centers for Disease Control page is a good collection of information and further readings. They recommend facility tests to measure diacetyl and its cousin 2,3-pentanedione, and better ventilation, worker safeguards and personal protective equipment as necessary. They also note that at least five workers in large scale coffee processing plants have been diagnosed with bronchitis obliterans.

    A Company that Specializes in Profiting from Harm

    The LA Times has an interesting investigation on the activities of Amvac.

    Pesticide maker sees profit when others see risks – Los Angeles Times

    Amvac is a leading maker of organophosphates, a class of older, highly toxic pesticides that has been under regulatory scrutiny since the late 1980s. As larger firms have stopped manufacturing some of their organophosphates, Amvac has bought the rights to make or sell 10 of them since 1989, according to company records and interviews. One of them, mevinphos, was banned in the U.S. in 1994 after a study by the U.S. Environmental Protection Agency found that it was responsible for poisoning more field workers in California than any other agricultural chemical. Amvac continues selling the product overseas, according to company officials. Amvac is by no means the largest producer of pesticides that have attracted regulatory scrutiny, but the company stands out for its willingness to embrace chemicals that other firms have abandoned.

    Amvac Slogan

    Love that slogan, don’t ya’! There are so many loopholes in pesticide regulation that a company like Amvac can post impressive profits by using these loopholes, having a significant say in the writing of the regulation, and effortlessly denying and delaying action. It’s a well researched piece, read in full.
