Effects of Fluoride Emissions on Snow Cover Pollution in Bratsk in the Winter of 2016/2017

Data on the fluoride fallout to the snow cover in Bratsk (the Irkutsk oblast) are analyzed to enhance the snow cover pollution presentation and monitoring data interpretation. The simulation of the fallout of fluorides emitted by the aluminum plant in Bratsk in the winter of 2016/2017 was carried out using the MRR-2017 approach. The comparison of the calculated fluoride fallout density fields with the data provided by the local Administration for Hydrometeorology and Environmental Monitoring demonstrated that the calculated values of long-period concentrations and fallout densities of fluorides at the individual observation points in the Bratsk area are in good agreement. The results support the applicability of the MRR-2017 approach for evaluating and generalizing measurements of snow cover chemistry.
