Huge oil plumes found under Gulf as BP struggles
Oil from a blown-out well is forming huge underwater plumes as much as 10 miles long below the visible slick in the Gulf of Mexico, scientists said as BP wrestled for a third day Sunday with its latest contraption for slowing the nearly month-old gusher.
BP, the largest oil and gas producer in the U.S., has been unable to thread a tube into the leak to siphon the crude to a tanker, its third approach to stopping or reducing the spill on the ocean floor. Engineers remotely steering robot submersibles were trying again Sunday to fit the tube into a breach nearly a mile below the surface, BP said. ...

Rivers closest to Toronto have highest concentrations of PCBs, other chemicals: study
A University of Toronto study of the concentrations of PCBs and other chemicals in the rivers running into Lake Ontario reveals significantly higher concentrations in areas closest to the centre of Toronto, an indication of the profound effects the city has on water quality.... The team looked specifically at concentrations of chemicals that have been strongly associated with human health problems: polychlorinated biphenyls (PCBs), a banned industrial chemical from the 1970s; polycyclic musks, a common fragrance compound used in a range of personal care products; polybrominated diphenyl ethers, a recently banned flame retardant; and polycyclic aromatic hydrocarbons, a toxic byproduct of fossil fuel combustion in the rivers. They also measured the concentration of these chemicals in air, soil and rain.
"In the Humber River watershed we saw an almost 100-fold increase in concentrations of polycyclic musks in the river water in the downtown area around Old Mill compared with parts of the river north of the city," said Matthew Robson, a research fellow in the Department of Geography and Program in Planning. "We saw similar increases in concentrations for all of the other chemicals in air, rain and soil...." ...

China scientists find use for cigarette butts
Chemical extracts from cigarette butts -- so toxic they kill fish -- can be used to protect steel pipes from rusting, a study in China has found.
In a paper published in the American Chemical Society's bi-weekly journal Industrial & Engineering Chemistry Research, the scientists in China said they identified nine chemicals after immersing cigarette butts in water.
They applied the extracts to N80, a type of steel used in oil pipes, and found that they protected the steel from rusting. ...

Feds: State pollution regulations too soft
MERRILLVILLE -- The state of Indiana is too lax in its proposed rules for when polluters can discharge more pollution into Lake Michigan and other lakes and rivers, the U.S. Environmental Protection Agency says.
In some circumstances, revamped state rules would allow up to 2.5 times more pollution than federal law allows, the EPA says.
By request from environmentalists, the agency has intervened to require the Indiana Department of Environmental Management to change the rules to make them acceptable. ...

BP's Hayward in 'battle' for hearts and minds
One man sits in a room surrounded by eight empty bottles of water as if he has not moved in hours. On a table in another room, name cards from Halliburton, Oceaneering and others who have offered assistance are scattered across a table spread with papers.... Yet, Tony Hayward, BP's chief executive, appears to be taking it all in his stride. He began at 6am on Wednesday in discussions with the US secretaries of energy and the interior, Steven Chu and Ken Salazar, as well as top scientists and engineers on BP's efforts to cap and contain the leak.
That ended close to noon, when he had a conference call with BP's board - something he has been doing every week to 10 days to update them on progress.... "We will only win this if we can win the hearts and minds of the local community," he said. "It's a big challenge."... "Apollo 13 did not stop the space programme. The Air France airplane that fell out of the sky off of Brazil did not stop the aviation industry,'' he said.... "I've actually got some good friends through this," he said, noting he had been dealing with people he would not ordinarily. "We are fighting a battle." ...

Baby vaccine contaminated with pig virus
Swine viruses are back - but this time they don't seem to be making anyone sick.
The US Food and Drug Administration (FDA) has reported that stocks of Merck's Rotateq vaccine against rotavirus are contaminated with the pig viruses PCV1 and PCV2. But the agency has not advised doctors to stop using it as the pig viruses aren't known to cause disease in humans, and rotavirus kills roughly half a million infants worldwide each year. An FDA advisory panel said the vaccine's benefits still outweigh its risks.
The FDA plans to monitor recipients for pig virus-related illness. "There will be quite careful monitoring of the people that have received the vaccine and I think that's entirely appropriate," says virologist Stephen Hughes, who advised the FDA on the issue.
Rotavirus vaccines are mainly given to infants in the developing world, where the virus is most likely to kill. ...

That way, when the pig virus mutates, these infants will be pre-vaccinated!

BP to try golf long shot to stop Gulf of Mexico oil leak
BP was last night considering a new plan of attack in its attempts to stop a massive oil leak in the Gulf of Mexico - blocking the ruptured well with golf balls and rubber tyres.
Forced back to the drawing board following the failure of a salvage effort on Saturday - when a 120-tonne steel box was lowered to the seabed to cover the leak, only to become blocked by icy sludge - it was looking into changing tack with an operation that its chief executive, Doug Suttles, likened to "stopping up a toilet."
Thad Allen, commandant of the US Coast Guard, explained: "The next tactic is going to be something they call a 'junk shot'.
They're actually going to take a bunch of debris - shredded up tyres, golf balls and things like that - and under very high pressure shoot it in...and see if they can clog it up and stop the leak." ...

Gosh, if that doesn't work, how about a giant piece of bubblegum?
