The model showed that the deep-sea dispersant
injection had a profound effect on air quality at the sea surface.
Given the lack of epidemiologic research into the effects of dispersant
exposure on human health, our study used data from a large cohort of workers participating in the Deepwater Horizon OSRC to assess two related objectives.
20], found that increase of amino groups in polar anchoring part of succinimide dispersant
increase the adsorption affinity of dispersant
onto the adsorbing surface which plays an important role in the stability of the suspensions.
High Energy Water-Accommodated Fraction, Chemically Enhanced Water-Accommodated Fraction, and Dispersant
Both the dispersant
and surfactant continuums share similarities and, in particular, they overlap significantly on the ends of the continuums where nonionic dispersants
and high-HLB ethoxylated surfactants serve very similar functions.
During the study, scientists tested lame from two coral species widespread in the Florida Keys in water containing the dissolved components of Deepwater Horizon oil, weathered oil, the dispersant
Corexite 9500 and the combination of oil and dispersant
Pedigo has aggressively challenged the EPA for, as he alleges, "not adhering to the spirit of the very Clean Water Act that the EPA is there to enforce by pre approving toxic Corexit dispersants
DOW Coating Materials says it will produce more dispersants
to meet fast growing demand from customers across the world.
Researchers from Utrecht University in the Netherlands and Florida State University examined the effects of the Corexit 9500A - a chemical dispersant
BP pumped into surface waters and at the wellhead in response to the spill.
He said, however, that Nigeria was better prepared this time, with some 210 tonnes of dispersant
being prepared to attack the spill, which has spread to an area between 35 and 45 miles (about 55-70km) in size.
Concerns about the toxicity and unprecedented amounts of Corexit being released into the environment prompted the EPA to request that BP consider safer alternatives to Corexit or state why it could not find a less toxic dispersant
Another benefit is the system's ability to allow for the full truck capacity to be used in high slump mixes, by enabling the truck to travel with low slump concrete and then automatically dose dispersant
to high target slump upon job site arrival.
Nearly 3 million liters (some 771,000 gallons) of a chemical dispersant
ejected into oil and gas from the Deepwater Horizon oil spill last spring and summer lingered until at least September, a new study shows.
He said the region already had strict dispersant
guidelines in place for the last 12 years.
In Part II the study is extended to survey most appropriate dispersant
and its optimal dose.
