| Outline of Final Research Achievements |
Methyl chloride (CH3Cl), a volatile organic compound emitted primarily from natural sources, is the major carrier of chlorine to the stratosphere, where it contributes to chlorine-induced destruction of ozone. Among a variety of natural sources, tropical forest ecosystems are considered the single largest source of CH3Cl. However, little is known about what controls the emission rates. In this study, we screened ~15 species of trees for CH3Cl emission by using a canopy crane to gain access to the canopy in a lowland tropical rainforest at Lambir Hills National Park, Malaysian Borneo. We found that chloride concentrations in leaf water might be a factor controlling emissions of CH3Cl from tropical trees.
