Photodegradation of Organophosphorus Pesticides in Water, Ice and Snow
Original language description
Organophosphorus pesticides (OPs) represent more polar compounds with better water solubility and higher degradation rates than organochlorine pesticides which made them attractive for a wide application in agriculture. OPs can be degraded both in abiotic and biotic compartments but they still belong to the group of compounds capable of the long-range transport. In the cold regions, snow and ice affect the processes of OPs deposition, accumulation and transformation and they can significantly alter their life times, degradation and elimination rates. However, our knowledge on photodegradation processes of OPs in the matrices of ice and snow is still very limited. Filling this gap is crucial for an enhancement of our understanding to the fate of the organic compounds in pristine arctic environments. This study is focused on the photochemical behaviour of fenitrothion and methyl-parathion as two currently used organophosphorus pesticides in the cold environments.
