一般說明

Bromomethane (methyl bromide) is the most effective soil fumigant for killing plant pests, its use is being phased out because its emissions from soil can lead to stratospheric ozone depletion. The bimolecular nucleophilic substitution (S(N)2) reaction of methyl bromide and OH- in aqueous solution has been investigated using a multilayered-representation quantum mechanical and molecular mechanics methodology.

Following the increasing international phasing out of methyl bromide for quarantine purposes, the development of alternative treatments for timber pests becomes imperative. The international accreditation of new quarantine treatments requires verification standards that give confidence in the effectiveness of a

Methyl bromide is a halogenated aliphatic hydrocarbon that exists as a colorless gas or a volatile liquid. Methyl bromide historically had been used in fire extinguishers but is more commonly used as a gas fumigant for soil-borne diseases and pests.

Although ozone-depleting methyl bromide was destined for phase-out by 2005, it is still widely applied as a consequence of various critical-use-exemptions and mandatory international regulations aiming to restrict the spread of pests and alien species (e.g. in globalized transport and
