CANCEROGENIC RISK OF ARSENIC CONTAMINATION OF WATER ECOSYSTEMS
Journal Title: Научно-практический журнал "Проблемы анализа риска" - Year 2016, Vol 13, Issue 3
Abstract
The geoecology of Chelyabinsk is characterized and assessment of arsenic contamination of its water ecosystems by content analysis of this substance by nuclear-absorbing speсtrophotometer method in rain and surface water, hydrophyte and bottom sediments is carried out. Results of the analysis showed that arsenic content in rain and surface water was though is lower than its maximum permissible concentration, but one order of magnitude that unambiguously points on significant contribution of atmospheric precipitations in contamination of river and lake water by this element. In the given case arsenic content increased on current course of the Miass river in water by 1.5 times, in common reed grass by 1.3 times, and bottom sediments by 2.1 times that testifies about increase of technogenic load on this water ecosystem.
