Abstract

The article reviews data on the mercury concentrations in coals of the South of Kuznetsk basin (Kuzbas) in Kemerovo region in Russia and in the surrounding soils. The Hg concentrations in the soil (30 samples) and coal (207 samples) were determined by the atomic absorption using RA-915+ mercury analyzer with pyrolytic attachment. The comparison with previous research showed that over the last 25 years the mean Hg concentration in the soils decreased by a factor of 2.8. Based on the dominating contribution of the coal dust and coal combustion products into the total Hg influx in the environment, it is possible to predict increase of the Hg background level in the city and the surrounding area along with the coal production growth in the area without using modern effective dust suppression.

煤矿区煤炭和土壤中的汞

摘要

本文回顾了俄罗斯克麦罗沃地区库兹涅茨克盆地南部（库兹巴斯）和周围土壤中汞含量的数据。土壤中的汞含量（30个样品）和煤中的汞含量（207个样品）是通过使用具有热解附件的RA-915 +汞分析仪通过原子吸收法测定的。与先前研究的比较表明，在过去25年中，土壤中的平均Hg浓度降低了2.8倍。根据煤尘和煤燃烧产物对环境中总Hg流入的主要贡献，可以预测城市和周边地区Hg背景水平的增加以及该地区煤炭产量的增长情况。使用现代有效的抑尘技术。
