Investigators believe the toxic pesticide ethyl bromide is to blame. The pesticide was banned for indoor residential use in the U.S. more than 30 years ago. An EPA official told ABC , "It can ...
Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group. It is abbreviated by chemists as EtBr (which is also used as an abbreviation for ethidium bromide ). This volatile compound has an ether-like odor.
High levels of bromide chronically impair the membrane of neurons, which progressively impairs neuronal transmission, leading to toxicity, known as bromism. Bromide has an elimination half-life of 9 to 12 days, which can lead to excessive accumulation. Doses of 0.5 to 1 gram per day of bromide can lead to bromism.
Bromide salts are used in hot tubs as mild germicidal agents to generate in situ hypobromite. The bromide ion is antiepileptic and as bromide salt, is used in veterinary medicine in the US. The kidneys excrete bromide ions. The half-life of bromide in the human body (12 days) is long compared with many pharmaceuticals, making dosing challenging ...
Toxicology tests on the ingredients of drinks consumed by seven tourists who fell ill in Fiji showed “no methanol or illicit substances,” authorities on the South Pacific island said Wednesday.
Most use of ethidium bromide in the laboratory (0.25–1 μg/mL) is below the LD50 dosage, making acute toxicity unlikely. Testing in humans and longer studies in a mammalian system would be required to fully understand the long-term risk ethidium bromide poses to lab workers, but it is clear that ethidium bromide can cause mutations in ...
This is the list of extremely hazardous substances defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. § 11002).The list can be found as an appendix to 40 CFR 355. [1]
