Photochemical degradation of persitent organic pollutants

Original language description

Persistence, bioaccumulation potential, and toxicity are important characteristics of many organic compounds. They are the subjects of long-range atmospheric transport, and deposition in cold ecosystems at high elevations and latitudes, where they can undergo various chemical and photochemical reactions. The study of possible phototransformations of the persistent organic pollutants (POPs) in ice and snow have been in the centre of our attention in recent years. Methodology for laboratory modelling of environmental photochemistry in the rigid matrices, with the special focus on the water ice, was developed, and several papers based on this topic were published. Now we established a new technique for simulation of processes occuring in natural snow in laboratory conditions. It includes the study of evaporation, migration, primary and secondary photochemical transformations of POPs. The first results from those experiments, and a comparison with the similar studies in natural conditions
