摘要：

Chloromethane (CH3Cl or methyl chloride) is a trace gas in the atmosphere that is a characteristic emission of vegetative biomass burning. Measurements of chloromethane emissions from laboratory-scale fires in forest fuels show that CH3Cl emission factors vary considerably between flaming and smoldering combustion. Regression analysis indicates that CH3Cl emission factors can be predicted from three fire and fuel parameters: combustion efficiency, rate of heat release, and fuel chloride content. The percentage of chlorine in the fine particle emissions from burning forest fuels also varies with combustion conditions. A combustion reaction mechanism is proposed to explain the observed variation in chlorinated emissions.
