Due to the tendency to an increase in industrial emissions into the environment and pollution of flora and fauna with various ecotoxicants, we studied the samples of vegetable oils for the content of heavy metals (Pb, Cd, Cu, Fe) by the method of atomic absorption spectroscopy (AAS). We established that the content of the determined elements was in the range from 0.037–1.474 mg/kg, we also found that in 20 % of the samples the lead content was below the method’s detection limit. Based on the obtained data, we calculated the possible intake of heavy metals into the human body with these oils and we evaluated the safety of their use.
