The study of the mercury content in fish and non-fishery objects by methods of atomic absorption spectrometry
Abstract
Mercury is one of the most dangerous and high toxic element which has ability to accumulate in plants, animal and human body. Fish and sea products in different degree are capable to accumulate mercury compounds. The content of mercury and harmful substances depends on the specie, size and lifetime. There are presented the results of research of the total content of mercury in fish samples according to species, as well as the non-fishery objects presented for tests in 2016. After the results analysis all the samples were divided into 3 groups. The level of accumulation of mercury in sea and river fish was determined. The research allowed identifying fish species potentially unsafe due to high level of mercury content. The control of mercury content was carried out by the method of cold vapor atomic absorption spectrometry with preliminary mineralization of the sample under pressure.
