Abstract

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.

2016/2017年冬季氟排放对布拉茨克积雪污染的影响

摘要

分析了布拉茨克（伊尔库茨克州）积雪覆盖的氟化物沉降数据，以加强积雪污染的呈现和监测数据解释。使用 MRR-2017 方法对 2016/2017 年冬季布拉茨克铝厂排放的氟化物沉降进行了模拟。将计算出的氟化物沉降密度场与当地水文气象和环境监测局提供的数据进行比较表明，布拉茨克地区各个观测点的氟化物长期浓度和沉降密度计算值吻合良好. 结果支持 MRR-2017 方法在评估和推广积雪化学测量方面的适用性。
