The intensive industrial and technological development results in an appaerance of a large amount of pollutants and harmful substances in the biosphere including large quantities of heavy metals. Some heavy metals are biogenic (Cu, Zn, Se etc.) and essential for proper maintaining of the metabolism in the human body. The main dangers to the human health are associated with the exposure to toxic elements such as Pb, Cd, Hg and As. Emission of Cd in the environment has increased during the 20th century mainly due to the recycling of the products containing this element. Cadmium accumulates in the human body with a biological half-life from 10 to 30 years and could cause very serious toxic effects. Cosmetic products are potentially a source of cadmium as well as some other heavy metals mostly due to the frequent and uncontrolled usage of cosmetics of poor and/or suspicious quality. The goal of the study is to determinate the cadmium content in various cosmetic products (lipsticks, eyeshadows and blushes) present in the markets of the Republic of Srpska. The content of Cd was determined with atomic absorption spectrophotometry (AAS) after the extraction with diluted HCl and aqua regia. The results of the research show that the cadmium concentrations in the investigated products are in accordance with the regulations of the Republic of Srpska (Regulations on safety of consumer goods; „Official Gazette RS“ – No.17/15). Acknowledgments: This work was done within the framework of the research project No. 19/06-020/961-26/15 supported by the Ministry of Science and Technology of Republic of Srpska.
