The ecotoxicological aspects of using the marine benthic invertebrates skeleton in the production of active calcium substances

Abstract

Abstract Marine benthic invertebrates are susceptible to the accumulation of heavy metals and other pollutants from the environment, leading to the impossibility of their use as raw materials in the food production and pharmaceutical industry. In this paper, the accumulation of heavy metals in the shells and needles of Strongylocentrotus sea urchins was studied to assess the safety of the use of this raw material in the production of active calcium substances for food and medical purposes with the use of voltammetry analysis and capillary electrophoresis. High levels of strontium accumulation in the studied samples were revealed, indicating the unfavorable situation of commercial waters with respect to the presence of mobile forms of strontium.
