Toxicologist and marine biologist Riki Ott has also spoken on the toxicity of the spilled crude oil and of the dispersant Corexit, "The dispersants used in BP's draconian experiment contain solvents, such as petroleum distillates and 2-butoxyethanol. Solvents dissolve oil, grease, and rubber.
Corexit 9500 was designed to replace Corexit 9527. In 2002, Corexit 9527 and Corexit 9500 were the only two chemical dispersants stockpiled in large quantities in the U.S.A. [ 15 ] An estimated 2.5 million gallons of chemicals were used in response to the supertanker SS Torrey Canyon oil spill in the United Kingdom in 1967 . [ 16 ]
An oiled gannet seabird getting the oil washed off.. Most of the impact was on the marine species. Eight U.S. national parks were threatened [4] and more than 400 species that live in the Gulf islands and marshlands are at risk, including the endangered Kemp's ridley turtle, the green turtle, the loggerhead turtle, the hawksbill turtle, and the leatherback turtle.
Sign protesting use of toxic Corexit chemical dispersant in the Deepwater Horizon oil spill, at the Bastille Day Tumble, French Quarter, New Orleans Environmental scientists say the dispersants, which can cause genetic mutations and cancer, add to the toxicity of a spill, and expose sea turtles and bluefin tuna to an even greater risk than ...
Health effects of pesticides may be acute or delayed in those who are exposed. [1] Acute effects can include pesticide poisoning, which may be a medical emergency. [2] Strong evidence exists for other, long-term negative health outcomes from pesticide exposure including birth defects, fetal death, [3] neurodevelopmental disorder, [4] cancer, and neurologic illness including Parkinson's disease ...
Alternative sign Class 3 Flammable solids, self-reactive substances and solid desensitized explosives – Solids which, under conditions encountered in transport, are readily combustible or may cause or contribute to fire through friction; self-reactive substances which are liable to undergo a strongly exothermic reaction; solid desensitized ...
Negative values of the decimal logarithm of the median lethal dose LD 50 (−log 10 (LD 50)) on a linearized toxicity scale encompassing 11 orders of magnitude. Water occupies the lowest toxicity position (1) while the toxicity scale is dominated by the botulinum toxin (12). [107] The LD 50 values have a very wide range.
The sign is commonly referred to as a radioactivity warning sign, but it is actually a warning sign of ionizing radiation. Ionizing radiation is a much broader category than radioactivity alone, as many non-radioactive sources also emit potentially dangerous levels of ionizing radiation.
