Prediction of outdoor air concentrations and implied exposure of 1,3-dichloro-propene following its agricultural use as a soil fumigant
- DowElanco, Indianapolis, IN (United States); and others
Off-field air concentrations of 1,3-Dichloro-propene associated with the agricultural use of TELONE II soil fumigant can be predicted by integrating the use of the Industrial Source Complex Short Term (ISCST) air dispersion model and a field-source strength term derived from aerodynamic field volatilization flux evaluations. The predicted air concentration distributions associated with single field and regional TELONE II soil fumigant use scenarios have been tested and validated with ambient air sampling under various environmental and edaphic conditions. An understanding of the temporal and spatial distributions of air concentrations allows refined exposure and risk estimates for populations that reside in areas of soil fumigation activity to be determined. In addition, the impact of various residential exposure mitigation measures can be evaluated.
