Risk Assessment of Heavy Metals upon the Consumption of Rice and Buckwheat

Abstract

The aim of this study is to assess the non-carcinogenic and carcinogenic risks of heavy metals (Cu, Fe, Mo, Ni, Pb, Cd, Hg) throughout the consumption of rice and buckwheat. Estimated Daily Intake of heavy metals (EDI), Target Hazard Quotient (THQ), and Carcinogenic Risk (CR) were estimated. According to the results, the daily intake of heavy metals and the consumption rate of rice and buckwheat do not exceed the established tolerable daily intakes. However, taking into consideration the consumption of the studied products, the chronic exposure of nickel can pose a carcinogenic risk.
