The BP Oil Spill’s Toxic Effects Are Beginning To Be Seen, Scientist Frustrated By Lack Of Data
Oil/Water samples from Gulf…VERY TOXIC

Oil/Water samples from Gulf... VERY  TOXIC

This is a very compelling video from a concerned citizen who decided to take his own samples of oil found on the beach in Grand Isle, La and have them tested at a laboratory. In the water portion of the sample the lab found propylene glycol, an ingredient in Corexit 9500 and Corexit 9527A, at an estimated concentration of  430 parts per million. Propylene glycol only makes up 1-5% of the Corexit products, so, if this is indeed propylene glycol from Corexit then the concentration of Corexit as a whole is far higher.

According to EPA’s latest analysis of dispersant toxicity released in the document Comparative Toxicity of Eight Oil Dispersant Products on Two Gulf of Mexico Aquatic Test Species Corexit 9500 at a concentration of 42 parts per million killed 50% of the mysid shrimp tested and at a concentration of 130 parts per  million killed 50% of the silverside fish tested. Remember the lab found 430 parts per million of a material that makes up only 1-5% of the Corexit products.  This also does not include the toxicity of the oil itself or an oil/dispersant mix.

Researchers find evidence of oil spill in Gulf’s food chain

Yellow oil droplets can  been seen in a post-larval blue crab.

Oil droplets have been found beneath the shells of tiny post-larval blue crabs drifting into Mississippi coastal marshes from offshore waters.

The finding represents one of the first examples of how oil from the Deepwater Horizon spill is moving into the Gulf of Mexico’s food chain. The larval crabs are eaten by all kinds of fish, from speckled trout to whale sharks, as well as by shore birds.

The tiny droplets are visible under the transparent shells of the 2-millimeter-sized crabs collected in Davis Bayou, said Harriet Perry, director for the University of Southern Mississippi Gulf Coast Research Laboratory’s Center for Fisheries Research and Development.


Spill’s extent and the effects surprising those studying it

Scientists knew weeks ago that much of the oil gushing from a blown-out oil well deep in the Gulf of Mexico remained below the surface, suspended in deep, cold water.

But research they are doing now has surprised them at the extent of the spill and effects on marine life, University of Georgia oceanographer Samantha Joye said Tuesday in UGA’s Marine Sciences Building. Joye, one of the leading scientists tracking the spill, spoke at a weekly update on her research team’s findings.

Seawater samples the team took during a June research voyage had to be diluted before analytical machines could accurately measure the oil levels in them, she said Tuesday.

Other scientists analyzing the samples still haven’t told Joye the precise concentrations of oil they’ve found in the water. But they’ve seen enough to know the levels are much higher than what was found in an earlier research cruise in May, when they measured oil contamination in parts per million or parts per billion in areas close to the spill.

The more recent water samples, many taken hundreds of feet deep in the Gulf, contain much more oil, she said.

The water samples come from in and around vast plumes of oil, methane and other chemicals mixed with sea water that have been pouring out of a broken oil well since a BP-owned drilling rig, the Deepwater Horizon, exploded April 20 and sank four days later.

Gulf Oil Spill: Scientists Beg For A Chance To Take Basic Measurements

By Dan Froomkin

A group of independent scientists, frustrated and dumbfounded by the continued lack of the most basic data about the 77-day-old BP oil disaster, has put together a crash project intended to definitively measure how much oil has spilled and where and how it is spreading throughout the waters of the Gulf of Mexico.

An all-star team of top oceanographers, chemists, engineers and other scientists could be ready to head out to the well site on two fully-equipped research vessels on about a week’s notice. But they need to get the go-ahead — and about $8.4 million — from BP or the federal government or both. And that does not appear imminent.

The test is designed to provide responders to future deep-sea oil catastrophes with valuable information. But, to be blunt, it would also fill an enormous gap in the response to this one.
