Melamine movin' on up the food chain

The tale is told from the pig’s viewpoint. Of course, as I have mentioned before, hog factories are evil and affect the people (mostly poor and black) who live around them in very many horrible ways.

Pig Out – NY Times

Of the 60 million pigs in the United States, over 95 percent are continuously confined in metal buildings, including the almost five million sows in crates. In such setups, feed is automatically delivered to animals who are forced to urinate and defecate where they eat and sleep. Their waste festers in large pits a few feet below their hooves. Intense ammonia and hydrogen sulfide fumes from these pits fill pigs’ lungs and sensitive nostrils. No straw is provided to the animals because that would gum up the works (as it would if you tossed straw into your toilet).

In my work as an environmental lawyer, I’ve toured a dozen hog confinement operations and seen hundreds from the outside. My task was to evaluate their polluting potential, which was considerable. But what haunted me was the miserable creatures inside.

They were crowded into pens and cages, never allowed outdoors, and never even provided a soft place to lie down. Their tails had been cut off without anesthetic. Regardless of how well the operations are managed, the pigs subsist in inherently hostile settings. (Disclosure: my husband founded a network of farms that raise pigs using traditional, non-confinement methods.)

The stress, crowding and contamination inside confinement buildings foster disease, especially respiratory illnesses. In addition to toxic fumes, bacteria, yeast and molds have been recorded in swine buildings at a level more than 1,000 times higher than in normal air. To prevent disease outbreaks (and to stimulate faster growth), the hog industry adds more than 10 million pounds of antibiotics to its feed, the Union of Concerned Scientists estimates. This mountain of drugs — a staggering three times more than all antibiotics used to treat human illnesses — is a grim yardstick of the wretchedness of these facilities.

ES&T Online News: E-waste recycling spews dioxins into the air

When computers, televisions, music systems, and other electronic products reach the ends of their lives, they often end up in China or other developing countries as e-waste. Such waste is a serious environmental threat in these parts of the world because of the poorly regulated conditions under which the waste is dismantled. A new study published in ES&T (DOI 10.1021/es0702925) shows that Guiyu, a major e-waste recycling center in China, has the highest documented levels of atmospheric polychlorodibenzo-p-dioxins (PCDDs) and polychlorodibenzofurans (PCDFs) in the world.

In e-waste recycling centers in China, discarded products are dipped into open pits of acid and heated over grills fueled with coal blocks to extract precious metals, such as gold. These processes often release toxic metals, such as lead, and organic compounds, such as dioxins. The emissions are not regulated, and occupational exposure is high because of the poor working conditions for e-waste recycling laborers.

In March 2007, researchers at Hong Kong Baptist University showed that soil at e-waste recycling sites in China has high levels of dioxins and polybrominated diphenyl ether (PBDE) flame retardants. (Read the paper at ES&T‘s ASAP website.) More recently, another study published in ES&T showed that the workers at these sites have blood levels of the heavy PBDE, BDE–209, 50–200 times higher than those previously reported. Whereas dioxins are potentially carcinogenic for humans, PBDEs affect thyroid metabolism and brain development.

In the current study, Ping’an Peng of the Guangzhou Institute of Geochemistry (China) and his colleagues sampled the air from Guiyu for a week in both the summer and the winter and analyzed the samples for 2,3,7,8-PCDD/Fs. The levels varied between 64.9 and 2765 picogram per cubic meter (pg/m³). The toxic equivalents (TEQ)—a value used to account for the different levels of toxicity of the individual dioxins—was 0.909–48.9 pg TEQ/m³. Given that Guiyu has no municipal or medical solid-waste incinerators, which are known to be major sources of dioxins, the authors attributed the elevated dioxin levels to e-waste recycling.

The team also found that the dioxin concentrations in the air around Guiyu were 12–18 times higher than those in Chendian, a town 9 kilometers (km) from Guiyu, and 37–133 times higher than those in Guangzhou, which is 450 km from the e-waste site. The results suggest that dioxin pollution from e-waste recycling is spreading to nearby areas.

When they calculated the exposure of adults to dioxins through inhalation, the researchers found that it (68.9 and 126 pg TEQ per kilogram per day in the summer and winter, respectively) was a whopping 15–56 times higher than the World Health Organization recommended maximum of 1–4 pg TEQ/kg/day.

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.

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.

Canada is expected to formally declare on Saturday that the controversial chemical bisphenol A (BPA) is a hazardous substance.

The move will make Canada the first country in the world to put the chemical on a list of toxic substances that will ban the material from being used in such products as baby bottles.

Good for Canada. Timing of when cans (the biggest potential source of adult exposure) will be BPA free is up in the air.
