Abstract: The concentrations of Potential Toxic Elements (Zn, Cd, Ni, Cr, As, V, Cu, Pb, Ba, and Hg) in air at Omoku, Obrikom and Elele-Alimini communities in Rivers State were determined using Shimadzu AA-6650 Atomic Absorption Spectrophotometer following ASTM D1971/4691 method after collection on glass fibre filters. Potential health risk assessment of children and adults exposed to the metals were estimated using United States Environmental Protection Agency (USEPA) standards; assessment of non-carcinogenic risks was done by estimating the hazard quotient (HQ) while Carcinogenic risk was evaluated by target cancer risk (TCR). Non-carcinogenic risks assessment of the metals evaluated in the three main pathways of ingestion, inhalation and dermal contact respectively showed that Total Hazard Quotient (THQ) and Total Hazard......
