Acute Environmental Toxicity and Persistence of a Chemical Agent Simulant: 2-Chloroethyl Ethyl Sulfide (CEES)

摘要

This report provides detailed information regarding a series of laboratory environmental fate and effects tests that were performed with the chemical agent simulant, 2-chloro-ethyl ethyl sulfide (CEES). Aerosols of CEES were generated within a Henderson chamber to allow exposure of plants, soils, and soil microbial communities. Additionally, aerosols were generated for exposure of freshwater aquatic organisms. Aerosols were characterized for mass concentration and particle size with chemical content of the aerosols being determined by GC/MS. Results for both aerosolized and surface-deposited CEES indicate that its vapor pressure is high enough to result in mixed gas and liquid phases. These affect the overall rate of deposition to surfaces. Environmental persistence, Vegetation surfaces, Soil surface, Environmental effects, Plants. (JES)
