Abstract: Toxic metals contamination is an important environmental problem that was mainly manifested in the growing industrial cities where the levels in toxic metals exceeded the recommended levels leading to the increase of several health problems varying from memory disorder to carcinogenic diseases. The study was aimed at evaluating heavy metal contamination from selected alcoholic and non-alcoholic drinks sold in Nigeria. Ten (10) alcoholic and non-alcoholic drinks were purchased in Yenagoa and standard wet digestion procedure was adopted in the sample preparation. Heavy metals were analyzed using the Atomic Absorption Spectrophotometer technique and the results were compared with World Health Organization (WHO) standards. The result shows the contamination of heavy metals for non-alcoholic drinks were PBC>PBCM >PBO >PCC >PF while Alcoholic drinks were BH > BL > BE > BS > BB. When compared to WHO standards, the levels of Cd, Ni, Pb were above the permissible limits. These results suggest that both alcoholic and non-alcoholic drinks sold in Nigeria may be contaminated with heavy metals which constitute a major public health problem. Thus, quality control is recommended during the production process especially at the stages of sterilization and purification.
