Estudio exploratorio de evaluación de riesgo en la salud de madres lactantes por consumo de pescado contaminado del río Cauca, en el Valle del Cauca (Colombia)

Cadmium (Cd), mercury (Hg) and lead (Pb) concentration was quantified in the fish Prochilodus magdalenae (bocachico) and Chaetostoma spp. (corroncho). The health risk due to consuming this fish was estimated in lactating mother living in three locations along the Cauca River. Carcinogenic and non-carcinogenic risk was quantified by using probabilistic modeling with Crystal Ball 11.0O and applying the Monte Carlo simulation model for 100,000 iterations. The average concentration was measured for the following metals: Cd = 46 μg/kg-1, Hg = 235 μg/kg-1, and Pb = 35 μg/kg-1. Regarding the mercury, in two locations in Cali, it was found that the values for non-carcinogenic risk and tolerable weekly consumption are above maximum limits allowed by the USEPA.
