title: Risk assessment on mixture toxicity of arsenic, zinc and copper intake from consumption of milkfish, Chanos chanos (Forsskål), cultured using contaminated groundwater in Southwest Taiwan.
abstract: Studies on bioaccumulation of arsenic, zinc, and copper in freshwater-cultured milkfish were carried out to assess the risks on human health. The arsenic, zinc, and copper levels in milkfish showed significant positive correlations to the arsenic, zinc, and copper concentrations in pond water. The hazard index of arsenic, zinc, and copper mixture for intake of milkfish (1.75 +/- 0.65) demonstrated that intake of in this way contaminated milkfish will result in non-carcinogenic risk. The target cancer risk of arsenic for intake of the milkfish (2.74 x 10(-4) +/- 1.18 x 10(-4)) indicated that the inhabitants were exposed to arsenic pollution with carcinogenic risk.
