Puzzle persists for 'degradeable' plastics
Eco-friendly plastics disintegrate, but might just linger in the environment. The environmentally friendly version of polythene might not be so friendly after all.
Polyethylene is one of the most widely used materials in the world, and the discarded plastic bag has become one of the most potent symbols of human impact on the environment. As worries over the vast scale of waste from this plastic has grown, so has the use of purportedly 'degradable' forms of it... Although it is clear that 'degradable' plastic bags, for example, will fall apart in the environment, the resulting fragments can persist for a long time, and there are no long-term studies on these pieces. A key issue is that products can be described as biodegradable without reference to the timescale it takes them to fully biodegrade. ...

In terms of how long it takes to biodegrade, are we talking Newtonian or relativistic timescapes?

GOP Begins New Push to Delay EPA Rules on Toxic Power Plant Emissions
Under pressure from industry, Congressional Republicans are urging the U.S. EPA to further delay long-overdue rules that would limit more than 80 air toxics emitted by coal-burning power plants, barely a month after the agency announced them.
At least one lawmaker, Rep. Edward Whitfield of Kentucky -- a state which gets more than 90 percent of its power from coal -- has said he will soon introduce legislation to postpone implementation of the regulations... According to EPA, the mercury and air toxics standards alone would prevent up to 17,000 premature deaths and 11,000 heart attacks each year.
Utilities and business groups say the anti-pollution rules would be too costly to implement and would force early shutdowns of power plants, threatening jobs and economic recovery. ...

Drilling fluid gushes from northern Pa. gas well
A blowout at a natural gas well in rural northern Pennsylvania spilled thousands of gallons of chemical-laced water Wednesday, contaminating a stream and leading officials to ask seven families who live nearby to evacuate as crews struggled to stop the gusher.
Chesapeake Energy Corp. lost control of the well site near Canton, in Bradford County, around 11:45 p.m. Tuesday, officials said. Tainted water flowed from the site all day Wednesday, though by the mid-afternoon, workers had managed to divert the extremely salty water away from the stream. ...

Seafood At Risk: Dispersed Oil Poses a Long-Term Threat
After the Deepwater Horizon oil rig exploded on April 20, 2010, more than 200 million gallons of oil flowed out of the Macondo well and into the Gulf of Mexico before the leak was finally plugged. Add to that the nearly 2 million gallons of the dispersant Corexit subsequently applied to the spill and it's no wonder that the government, scientists and the public alike are wondering what sort of effects this chemical cocktail will have on the Gulf ecosystem, and especially seafood. While the mainstream media has widely covered the debate over seafood safety, these stories do not delve into the science behind the issue, nor do they highlight the dangers that chemically dispersed oil poses to the marine food web. Not only is there concern about the current safety of Gulf seafood, but there are concerns about the long-term effects dispersed oil may have on fish populations, further jeopardizing Gulf fisheries in the future....
The current FDA risk assessment protocol is based on a 176-pound man eating four shrimp a week. That doesn't account for women or children, whose body weights are lower, let alone local seafood consumption along the Gulf coast. "Nobody in the Gulf really eats four shrimp a week, so it's unrealistic the way they are assessing risk of consumption," says Shaw....
Solomon reports that many people she talked to on the Gulf coast told her, "Four shrimp?! That's not even one po' boy!" ...

Long-term threats are tomorrow's problem.

Fossil fuel firms use 'biased' study in massive gas lobbying push
Senior executives in the fossil fuel industry have launched an all-out assault on renewable energy, lobbying governments and business groups to reject wind and solar power in favour of gas, in a move that could choke the fledgling green energy industry.
Multinational companies including Shell, GDF Suez and Statoil are promoting gas as an alternative "green" fuel. These companies are among dozens around the world investing in new technologies to exploit shale gas, a controversial form of the fuel that has rejuvenated the gas industry because it is plentiful in supply and newly accessible due to technical advances in gas extraction known as "fracking"....
Burning gas in power stations releases about half the carbon emissions of coal, allowing gas companies to claim it is a "green" source of fuel.
Central to the lobbying effort is a report claiming that the EU could meet its 2050 carbon targets 900 billion euros more cheaply by using gas than by investing in renewables. But the Guardian has established that the analysis is based on a previous report that came to the opposite conclusion - that renewables should play a much larger role. The report being pushed by the fossil fuel industry has been disowned by its original authors who referred to it as "biased" in favour of gas....
For the last two months, company lobbyists have been besieging government officials in Europe, the US and elsewhere to push the report. Their efforts are being boosted through alliances with energy-intensive industries, which are joining in the pressure on government in the hope of securing cheap energy. ...

It ain't biased if I agree with it, and it makes me more money.

AP Enterprise: BP is looking strong a year later
It's hard to tell that just a year ago BP was reeling from financial havoc and an American public out for blood.
The oil giant at the center of one of the world's biggest environmental crises is making strong profits again, its stock has largely rebounded, and it is paying dividends to shareholders once more. It is also pursuing new ventures from the Arctic to India. It is even angling to explore again in the deep waters of the Gulf of Mexico, where it holds more leases than any competitor. ...

Mother's diet during pregnancy alters baby's DNA
A mother's diet during pregnancy can alter the DNA of her child and increase the risk of obesity, according to researchers.
The study, to be published in the journal Diabetes, showed that eating low levels of carbohydrate changed bits of DNA.
It then showed children with these changes were fatter.
The British Heart Foundation called for better nutritional and lifestyle support for women.
It is thought that a developing baby tries to predict the environment it will be born into, taking cues from its mother and adjusting its DNA. ...

That developing baby might be best off just staying in the womb.

California's poor, Mexican American kids have among world's highest levels of flame retardants
Mexican American school children in California are contaminated with seven times more flame retardants than children in Mexico and three times more than their own mothers, according to a new study. The 7-year-olds in the Salinas Valley had more of the chemicals in their bodies than almost all other people tested worldwide. University of California scientists warn that the levels they found in the children "present a major public health challenge." Low income, rather than race or ethnicity, is probably the major factor in determining who is highly exposed to these chemicals. Household dust is likely the major source. ...

These kids may be poor but at least they won't catch on fire easily.

Methylmercury on the Rise in Endangered Pacific Seabirds
Using 120 years of feathers from natural history museums in the United States, Harvard University researchers have been able to track increases in the neurotoxin methylmercury in the black-footed albatross (Phoebastria nigripes), an endangered seabird that forages extensively throughout the Pacific.
The study shows that the observed increase in methylmercury levels, most likely from human-generated emissions, can be observed and tracked over broad time periods in organisms that live in the Pacific Ocean....
"Given both the high levels of methylmercury that we measured in our most recent samples and regional levels of emissions, mercury bioaccumulation and toxicity may undermine reproductive effort in this species and other long-lived, endangered seabirds."
They found increasing levels of methylmercury that were generally consistent with historical global and recent regional increases in anthropogenic mercury emissions. ...

USF study concludes that common fungicide is deadly to frogs
Two years ago some University of South Florida researchers began studying the effects of the most widely used fungicide in the country to see if it might kill more than just fungus.
Turns out it's also a pretty effective frog-icide.
"We were completely surprised to see it basically killed everything," said Taegan McMahon, the lead researcher on the study, which was published this week in a scientific journal called Environmental Health Perspectives. Frogs on farms with treated fields, frogs in ponds on golf courses, frogs in the back yard -- the fungicide could be lethal to any of them, the study suggests.
"We don't know what the effect on humans could be," she added. "And we use it heavily in Florida."
The fungicide, chlorothalonil, sold under such names as Bravo, Echo and Daconil, is used to treat farmers' fields, lawns and golf courses and is an ingredient in mold-suppressing paint.
It's part of the same chemical family, organochlorines, as the banned pesticide DDT. It is known to cause severe eye and skin irritation in humans if handled improperly.
Chlorothalonil kills mold and fungi by disrupting the respiratory functions of the cells, explained Jason Rohr, an assistant professor who co-authored the study and heads up USF's Rohr Ecology Lab. At this point the researchers don't know if that's how it kills frogs, too, he said. They just know it's lethal. ...

BP oil spill: Fishermen woes persist, one year on
He has brought me out on his boat, a couple kilometres from the Gulf of Mexico, to show me why.
He winches up a basket full of oysters and sifts through each one, shaking his head.
"This one's dead. This one's dead. All of them empty shells. All of them, beautiful oysters, and they're dead. And all because of BP's oil spill one year ago," he says.
Everything he has caught, he has to throw back.
"It's heartbreaking," he says. "This is the biggest oyster kill in Louisiana history, probably in the Gulf coast's history.
"I wish I wasn't part of it. I wish I wasn't here. It's heartbreaking."...
Back at the headquarters of Collins Oyster Company, Nick's father Wilbert stands in the driveway, taking a long drag on a cigarette.
At 73 years old, he is the head of the family business.
"We used to have some of the best oysters in the country," he says. "They used to line up here for three hours at a time to get a bag full."...
Now there are no cars lining up. Without any oysters, Wilbert has put up a sign on his front lawn.
It reads: "Collins Oyster Company - Out of Business After 90 Years Due to BP Oil Spill."

But the oysters that do survive will be that much stronger!

Potent new rat poisons killing California wildlife
Outside Palm Desert, a young bobcat dies mysteriously at a nature preserve. South of Nevada City, a farmer finds an owl dead near his decoy shed. In San Rafael, a red-shouldered hawk bleeds heavily from its mouth and nose before succumbing at an animal care center.
Each of those incidents shares a link to a widely used toxin that is turning up at dangerous levels in wildlife across California: rat poison.
Over the years, rat poison has spared state residents untold filth and disease. But a new generation of highly toxic, long-lasting poisons is killing not only rats, mice and ground squirrels, but whatever feeds on them, too....
"Rodenticides are the new DDT," said Maggie Sergio, director of advocacy at WildCare, a Bay Area wildlife rehabilitation center that has responded to dozens of poisoning cases. "It is an emergency, an environmental disaster. We are killing nature's own rodent control."...
Around Bakersfield, 79 percent of endangered San Joaquin kit foxes tested have turned up positive for rodenticide. Near Los Angeles, 90 percent of bobcats sampled had rat poison in their blood. "Basically, when we look for it, we find it," McMillin said....
Two tongue-twisting toxins turn up most often in wildlife: brodifacoum and bromadio-lone. On store shelves, they go by such names as D-Con, Havoc, Talon, Tomcat Ultra and Just One Bite.

"Killing nature's own rodent control" is just good business. Think of all those future rat poison sales!
