Pine Needles as a Biomonitor for Estimation of the Regional-Scale Distribution of Organic Pollutants

摘要

Classic methods of the monitoring of pollutants to determine areas of their distribution from the sources have many limitations. The direct regular sampling of atmospheric air with a required number of sites in the study area is not an easy task. Results of modeling of the transport of polluted air masses often contradict experimental data. As a natural accumulative pattern, snow cover pollution characterizes the atmospheric state only during winter. Moreover, due to a distinct anticyclonic pattern of atmospheric circulation in winter, some areas of East Siberia are characterized by the localization of emission nearby the sources. Therefore, we can use the data on snow cover pollution, primarily, to estimate the source capacity rather than the boundaries of polluted area. In this case, the application of biomonitors makes it possible to estimate atmospheric pollution based on results of the long-term communicative action of pollutants on the environment.
