This study aims at assessing non-carcinogenic and carcinogenic risks of trace elements (Pb, As, Cd, Hg, Mo, Cu, Fe) through the consumption of tap water and black coffee in Yerevan. The obtained results indicate that the estimated daily intake and non-carcinogenic risk values of the studied elements do not exceed the acceptable level. Nonetheless, the carcinogenic risk values of Pb exceed the risk limit of 1× 10-6 in case of black coffee consumption.
