"A TLV–TWA of 1 ppm (3.89 mg/m3) is recommended for occupational exposure to methyl bromide"-ACGIH 8 hour time weighted average. Immediately Dangerous To Life or Health Concentration by NIOSH: "The revised IDLH for methyl bromide is 250 ppm based on acute inhalation toxicity data in humans [Clarke et al. 1945].
A bromide ion is the negatively charged form (Br −) of the element bromine, a member of the halogens group on the periodic table.Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [3]
Other bromine isotopes are all radioactive, with half-lives too short to occur in nature. Of these, the most important are 80 Br (t 1/2 = 17.7 min), 80m Br (t 1/2 = 4.421 h), and 82 Br (t 1/2 = 35.28 h), which may be produced from the neutron activation of natural bromine. [32] The most stable bromine radioisotope is 77 Br (t 1/2 = 57.04 h).
The music video for "Dangerous" premiered on S-X's YouTube channel on 18 September 2020. [12] The video was co-directed by Troy Roscoe and Danyl Goodall. 1883 Magazine wrote, "In the music video, S-X finds himself in a multi-dimensional world of haunted mansions with a witchy -like cult, a dinner gathering full of deranged guests, and a spider ...
A 25-foot (7.6 m) wall of coal fly ash from the release of 5.4 million cubic yards ash slurry into the Emory River, Tennessee, in 2008. [1] The river water was contaminated with toxic metals including arsenic, copper, barium, cadmium, chromium, lead, mercury, nickel, and thallium. [2] Cleanup costs may exceed $1.2 billion. [3]

"Dangerous" was composed in 4 4 time and the key of B-minor, with a tempo of 103 beats per minute. It has a duration time of three minutes and thirty-seven seconds. [2] The chorus of the song (This is serious/We could make you delirious/You should have a healthy fear of us/'Cause too much of us is dangerous) was taken from a 1980s PSA produced by Kids Corner Ltd of Colorado Springs, Colorado ...
1,1,2,2-Tetrabromoethane, or simply tetrabromoethane (TBE), is a halogenated hydrocarbon, chemical formula C 2 H 2 Br 4.Although three bromine atoms may bind to one of the carbon atoms creating 1,1,1,2-tetrabromoethane this is not thermodynamically favorable, so in practice tetrabromoethane is equal to 1,1,2,2-tetrabromoethane, where each carbon atom binds two bromine atoms.
