The Environmental Safety of Fish Products
Abstract The anthropogenic pollution of the environment leads to the discharge of various pollutants into water ecosystems, which further accumulate in fish and other hydrobionts. Fish is a valuable traditional food source for humans, and the quality assessment for fish products is therefore a relev...

The highest relative content of heavy metals was observed in the livers of the whitefish. The content of cesium 137 is insignificant and below the allowed level of radionuclide activity. Conclusion: The analysis of the research results shows that the contents of heavy metals and cesium 137 in the fish caught in the lower reaches of the Lena do not exceed the standard levels. The on-going pollution of lakes and rivers within the Lena watershed calls for regular monitoring of heavy metal and radionuclide content and accumulation in game fish.
