Pesticides Fate Assessment
人们不断努力了解农药在农业实践中的应用对环境的影响。 科学家们一直在研究农药在土壤、水和大气之间的运动及其在运输过程中的转化。 农药从施用地点的运输经过几个过程,包括径流、向地下水的移动、挥发和风蚀。 监管界最近的努力集中在对挥发过程和喷雾漂移造成的偏离目标浓度进行量化。
The Center for Air Quality provides detailed investigation of fate and transport of pesticides subsequent to spray applications to the soil and plant surfaces. Novel laboratory assessments, and field monitoring evaluations and the development of modeling tools are designed and implemented to evaluate the impact of airborne contaminants. As part of this program the research team at Ohio University in collaboration with industry developed a robust emissions model to evaluate the volatilization of active ingredients from soil and plants following application. A hybrid platform was developed to provide realistic assessments of aerosolization, transport and deposition of pesticides by integrating volatilization and dispersion modeling. This modeling platform supports the industry and regulatory agencies to accurately evaluate the exposure risks of airborne species for a wide range of environmental conditions and pesticides.
