Infobox references. Bromomethane, commonly known as methyl bromide, is an organobromine compound with formula C H 3 Br. This colorless, odorless, nonflammable gas is produced both industrially and biologically. It is a recognized ozone-depleting chemical.
Bromoacetone is available commercially, sometimes stabilized with magnesium oxide. It was first described in the 19th century, attributed to N. Sokolowsky. [3] Acetone and bromine form bromoacetone. Bromoacetone is prepared by combining bromine and acetone, [4] with catalytic acid. As with all ketones, acetone enolizes in the presence of acids ...

International Standards For Phytosanitary Measures No. 15 (ISPM 15) is an International Phytosanitary Measure developed by the International Plant Protection Convention (IPPC) that directly addresses the need to treat wood materials of a thickness greater than 6mm, used to ship products between countries.
The term immediately dangerous to life or health (IDLH) is defined by the US National Institute for Occupational Safety and Health (NIOSH) as exposure to airborne contaminants that is "likely to cause death or immediate or delayed permanent adverse health effects or prevent escape from such an environment."
Chemical cartridge. A respirator cartridge or gas mask canister is a type of filter that removes gases, volatile organic compounds (VOCs), and other vapors from air through adsorption, absorption, or chemisorption. It is one of two basic types of filters used by air-purifying respirators.
Argentometry. In analytical chemistry, argentometry is a type of titration involving the silver (I) ion. Typically, it is used to determine the amount of chloride present in a sample. The sample solution is titrated against a solution of silver nitrate of known concentration. Chloride ions react with silver (I) ions to give the insoluble silver ...

The most efficient control method is preplant soil fumigation with methyl bromide (Mbr). That can reduce the M. incognita reproduction by almost 100%. [10] However, the soil fumigant methyl bromide has been phased out in 2005 because of its negative effects on the ozone layer.
