Flame Retardants and Hyperthyroidism in Cats

Caveat Emptor: They found a correlation, not a causative mechanism. But Polybrominated Diphenyl Ethers (PBDEs, yum!) have structures that can mimic endocrine hormones. Because hormones signal at very low doses and continuously, our whole toxicological risk testing structure of looking for acute effects at high doses and trying to extrapolate those effects to low doses is flawed for endocrine disrupting compounds. We are finally beginning to see some new research, especially with other toxics such as Bisphenol A, which test for chronic conditions and subtle gene and hormonal signalling effects at low doses. After all, small changes in hormone regulation especially at childbirth and a young age can have very serious effects later on in life.

Inside Bay Area – NEW: Flame retardants linked to thyroid disease in cats

A mysterious epidemic of thyroid disease in cats may be linked to flame retardants common in carpets, foam furniture and mattresses, according to U.S. Environmental Protection Agency researchers, who suggest that scientists have underestimated the damaging health risk the chemicals pose to humans.

The research, published Wednesday in the journal Environmental Science and Technology, does not prove these compounds, known as PBDEs, caused the rash of hyperthyroidism in the nation’s household cats over the past 30 years.

Rather, it lays out a hypothesis, showing that cats are heavily contaminated by these compounds, which leach from household products and are found everywhere, particularly household dust. Cats, meticulous cleaners, ingest PBDE-contaminated dust daily.

The case of fire retardants is especially difficult because they save many lives, so manufacturers can always point to that fact and resist change. The logical fallacy, however is as follows:

  1. Fire retardants save lives (therefore good)
  2. PBDEs are fire retardants
  3. Therefore, PBDEs are good!!

The search for a safer fire retardant needs to continue, and will not happen unless the old ones are under pressure of being phased out.

    Melamine Adulteration investigation gets cracking

    FDA agents raid pet food plant, offices – Yahoo! News

    WASHINGTON – Federal agents searched facilities of a dog and cat food manufacturer and one of its suppliers as part of an investigation into the widening recall of pet products, the companies disclosed Friday. Food and Drug Administration officials searched an Emporia, Kan., pet food plant operated by Menu Foods and the Las Vegas offices of ChemNutra Inc., according to the companies. Menu Foods made many of the more than 100 brands of pet food recalled since March 16 because of contamination by the chemical melamine. ChemNutra supplied the manufacturer with wheat gluten, one of the two ingredients tainted by melamine used in recalled pet products. Both companies said they were cooperating with the investigation.

    The initial “let’s blame China for everything” drumbeat is subsiding a little as the FDA finally begins its inspections, and we find the tangled web of the food import business unraveling just a little bit. At this point in time, the charges are flying like crazy.

    The origin within China of the wheat gluten and rice protein concentrate remains murky. For example, ChemNutra’s source for the twovegetable proteins, Suzhou Textile Import and Export Co., told The AP that food ingredients aren’t part of its business — but that employees often take on side deals. Stern said ChemNutra dealt with the company’s president.

    Side deals? How quaint? The solution is simple: Quarantine every food item from China until it has been tested for melamine. You do not know the extent of the problem yet. It only seems to get worse everyday. Make the manufacturers pay for the testing.  Tighten up the paperwork, exercise tighter control over where the ingredients come from, get everything in writing.

    Meanwhile, the manufacturers are getting their press releases out. From Blue Buffalo foods…

    We at the Blue Buffalo Company have just learned that American Nutrition Inc. (ANI), the manufacturer of all our cans and biscuits, has been adding rice protein concentrate to our can formulas without our knowledge and without our approval. This is product tampering, and it apparently has been going on for some time. The can formulas that we developed, and trusted them to produce, never contained any rice protein concentrate. It appears that only an FDA investigation of ANI’s rice protein concentrate supplies forced them to reveal this product tampering to us.

    While this activity by ANI is in itself unlawful, the situation is further clouded by the fact that ANI has been receiving rice protein concentrate from Wilber-Ellis, some of which the FDA has determined to be contaminated with melamine.

    If this is true (and we don’t know that for a fact), it’s plain ol’ cheating and food adulteration. What does American Nutrition have to say?

    The FDA has urged American Nutrition to issue a voluntary recall of pet foods manufactured using Wilbur-Ellis rice protein. None of these products is sold under an American Nutrition brand, but are sold through other independent companies. No American Nutrition brands or other products they manufacture for other businesses are affected by this recall.

    Why would I trust the word of anyone who’s accused of adding ingredients off the label? This story gets curiouser and curiouser, and it is pretty clear that between the “side dealers” in China and some greedy middlemen suppliers here, we have plenty of blame to go around.

  • Voluntary Priority and Toxic Chemical Reduction – US EPA

    Priority and Toxic Chemical Reduction | Resource Conservation Challenge | US EPA

    Priority and toxic chemicals make up a fairly limited volume, yet potentially hazardous portion of the nation’s waste stream. We are working to eliminate or reduce priority chemicals and other chemicals of national concern from commercial products, waste streams, and industrial releases through pollution prevention, waste minimization, and recycling/reuse.The 31 priority chemicals are federal priorities because they are persistent, bioaccumulative, and highly toxic. We’re focusing on reducing priority and toxic chemicals to better protect human health and the environment.

    By substituting or eliminating certain chemicals in their manufacturing processes, companies produce less waste and thus lower their waste disposal costs. Our goal is to substantially reduce the volume and toxicity of priority chemicals in waste by asking companies to voluntarily:

    • Substitute safer alternatives when they can;
    • Minimize the amount of priority chemicals they use, if they can’t substitute for them;
    • Maximize their recycling efforts;
    • Practice cradle-to-cradle chemical management; and
    • Design products to minimize exposure to, and release of, priority chemicals during manufacturing and use.

    Sounds good, and Worldchanging has more:

    But nowhere near the progress some companies are making on their own in cleaning up toxic emissions — not simply to be good guys, but to reduce their costs, liabilities, and exposure to activist and shareholder pressures. And, in some cases, to meet their customers’ growing demands for less-toxic or nontoxic alternatives to business as usual.

    Read the whole post, which sounds ambivalent about the scheme. The idea is Environmental Good Sense 101, use less, or none at all, practice cradle to grave economics and minimize exposure. Simple stuff, huh. The biggest problem, however, is that by setting limits on a voluntary basis, you always run the risk of setting the bar too low, and then indulging in relentless and pointless self congratulation about how the “market” solved everything, and how rules are so, well, 1970s?

    you need a good mix of

    1. Regulation, which sets a minimum, health based bar
    2. Flexibility to the business on how to achieve their targets
    3. Market systems to trade emission credits, etc
    4. Voluntary industry-government initiatives like the one above
    5. Relentless citizen activism that forces governments/business to act
    6. Community outreach and education so consumers can make informed choices
    7. Costing mechanisms that actually reflect free market efficiencies (no stupid subsidies, accurate costing of “externalities”, etc. )

    Yeah, this does not fit neatly into the Mano a Mano, you’re with us/you’re against us false dichotomy of choice that seems to beset almost every policy debate (environmental or otherwise). It seems that you never have to do one or the other, but a bit of both, or all of them at the same time.

    In the meanwhile, the voluntary program will work, but only in areas in specific instances where it is to a company’s advantage.

    BTW, I think that good old fashioned regulation in Europe – See Reach and many many more existing regulations, such as this one for PCBs and Dioxins which I know a little too much about, have a little more to do with American companies reducing POP levels that they care to admit!

  • BC Carbon Tax regressive?

    British Columbians with low incomes will benefit from the carbon tax in its first year, but will pay more by the scheme’s third year, a new study concludes.

    The impact of the tax and its offsetting income tax cuts will become increasingly unequal unless the provincial government increases payments to low-income earners, the study says.

    The study, by Marc Lee, senior economist with the Canadian Centre for Policy Alternatives, and Toby Sanger, senior economist with the Canadian Union of Public Employees, takes a detailed look at the fairness of the controversial tax.

    via Carbon Tax Whacks the Poor, Later :: News :: thetyee.ca

    The report makes some good points. Revenue neutrality (the offsetting of carbon taxes with income/corporate tax cuts) has nothing to do with reducing carbon emissions. If I were to redesign this tax, I would do as the report says, increase rebates to lower income people, reduce corporate tax cuts so that the resulting revenue can be used to fund more transit infrastructure, energy efficiency infrastructure and the building of a low carbon economy.

    A carbon tax in itself is not sufficient to reduce emissions. It does its part, but building an energy efficient, low carbon infrastructure will do a lot more and the money’s there, just use it.

  • Sethusamudram – A typical Indian development project

    The Sethusamudram (bridge sea – for the transliterators) project has the classic development plot lines that I’ve seen play out many times in India. Here’s a rationale from the official site…

    Currently the ships coming from the west coast of India and other western countries with destination in the east coast of India and also in Bangladesh, China etc have to navigate around Srilankan coast. The existing water way is shallow and not sufficient for the movement of ships. This is due to the presence of a shallow region known as Adam’s bridge, located southeast of Rameswaram near Pamban, which connects the Talimannar Coast of Srilanka

    What? They are going to destroy the bridge that rama and the vanaras built? Look at that picture, (thanks Manitham), can’t you see all the “Vanaras” (this has always struck me as racist – folks showing up from the North and calling the darker skinned Southerners Monkeys! But that is a different rant) running across the very clearly delineated land bridge – It’s fascinating, almost makes me believe that the Ramayana happened as narrated!

    Manitham has a good rundown of the project from an activist standpoint.

    A few points

    • The secrecy and lack of transparency are classic government techniques to control the flow of information and discourse. Every government does it, and the Indian government is no exception.
    • Environmental Impact Assessments are bought and paid for by the funding agency, and are hence essentially unreliable and untrustworthy. I had first hand experience of this when I was a student at IIT Bombay 10 years back.
    • There is a lot of politics involved, the port of Tuthukudi (Tuticorin as the damn Brits say) in Tamil Nadu is a clear winner and Colombo in SriLanka stands to lose revenue. There is also a great deal of Tamil Pride involved
    • Read this excellent article from the climate.lk clearinghouse of articles : There is a security dimension here for India that may have been the actual motivation.
    • The area, due to its sheltering and shallow waters, has a lot of marine life. From a 2004 Deccan Herald Article

    The series of meetings called by the Tuticorin Port Trust chairman in the coastal districts have turned out to be stormy with representatives of political parties shouting down objections from fishermen, who fear the loss of livelihood, and environmentalists who say the project threatens to destroy the Gulf of Mannar Marine Reserve. This reserve is one of India’s most biologically diverse coastal regions.
    Over 3,600 species of plants and animals are found here. It is the first marine biosphere reserve in the South and South-East Asia and is believed to have the highest concentration of seagrass species along India’s coast. It is also among the largest remaining feeding grounds for the globally endangered species dugong. Five different species of endangered marine turtles, innumerable fish, molluscs and crustaceans are also found here. The Bombay Natural History Society (BNHS), the largest NGO working in the field of bio-diversity and environmental conservation, has said the rapid Environmental Impact Assessment (EIA) report prepared by the National Environmental Engineering Research Institute (NEERI) is insufficient and a detailed study should be conducted in all seasons for at least a year.

    • The EIA actually says that since the seaway is 20 km away from the reserve, there will be no effect on the reserve, um, that seems highly unlikely to me…
    • The other major dimension is the usual utter lack of care for the people displaced. previous instances like the Sardar Sarovar project indicate that there will be no fair compensation for the displaced people, or for lost livelihood, which I guess is perfectly fine because it serves the greater good of the country?

    Most of these big projects have resulted in overstated gains, understated losses, and huge wastes of taxpayer money. I don’t trust this to be any different. The facts look fudged, the project seems unnecessary (where’s my tamil pride?) and the effect on the wildlife and the crazy complex current system around Sri Lanka may change significantly leading to unforseen micro climate effects.

    Two thumbs down…

    Gaping Reminders of Aging and Crumbling Pipes – New York Times

    Gaping Reminders of Aging and Crumbling Pipes – New York Times

    Local and state officials across the country say thousands of miles of century-old underground water and sewer lines are springing leaks, eroding and — in extreme cases — causing the ground above them to collapse. Though there is no master tally of sinkholes, there is consensus among civil engineers and water experts that things are getting worse.

    The Environmental Protection Agency has projected that unless cities invest more to repair and replace their water and sewer systems, nearly half of the water system pipes in the United States will be in poor, very poor or “life elapsed” status by 2020.

    Yes, sewers are unsexy, there’s no new fancy science involved. But water and sewer systems are the very basis of public health, and the biggest reason why Americans don’t die of sleeping sickness and dengue fever (or their subtropical equivalents) in large numbers evey year. People who want to cut taxes and limit government need to keep this in mind. There’s no money to be made out of building and maintaining sewers, it’s a dirty job and government has to do it, or else nobody will, and money is required. We produce the waste, we need to be taxed appropriately for it. It’s that simple.

    Endocrine Disrupting Chemicals – A new Resource

    Critical Windows of Development is a timeline of how the human body develops in the womb, with animal research showing when low-dose exposure to endocrine disrupting chemicals during development results in altered health outcomes.

    Critical Windows of Development

    This promises to be an easy to use database showing development timelines of infants, and the documented effects of endocrine disrupting chemicals at these timelines. The prime focus is bisphenol A and phthalates at this point in time. The Environmental Health News has more about the program here. It is not out for public consumption yet, so stay tuned…
