Technical Abstract: Atmospheric processes have been shown to be an effective means of transport for persistent organic pollutants, including some crop protection chemicals. Volatile components and residues bound to dusts can travel long distances in the atmosphere and be deposited far from the point of origin posing contamination risks to sensitive ecosystems. These processes depend on the pollutant's physical and chemical properties which govern partitioning between the air and different surfaces (i.e., water, plant surfaces, soil) and how quickly the pollutant will degrade. Agricultural and environmental management practices can also influence the fate of agrochemicals. A summary of these will be presented.
