Title: Determination of the Environmental Fate and Transport of Methyl Bromide
Description:
Abstract:
The primary objective of "Determination of the Environmental Fate and Transport of Methyl Bromide" is to determine soil reactions, the transport characteristics, volatile emissions and mass partitioning of methyl bromide to assess the environmental impacts of the agricultural use of methyl bromide. This research will provide the necessary information to determine, scientifically, the environmental effects from the agricultural use of methyl bromide. Collection Organization: University of California, Riverside Collection Methodology: Field experiments have been conducted to quantity methyl bromide emissions. The field studies were conducted on a 10-acre plot; the plot was covered with a tarp for the first experiment, and the soil left bare for the second experiment. The results of the first experiment, in which a mass balance was conducted, indicated that approximately 40% of the applied methyl bromide volatilized into the atmosphere. Very preliminary analyses of the data from the second (non-tarped) experiment indicate that approximately 30-40% of the applied methyl bromide volatilzed. Laboratory column studies have demonstrated that methyl bromide emissions can be siginificantly reduced by the addition of water to soil. Collection Frequency: Ongoing.
