A study was established to measure the total Hg concentration in the foot of Taqelus dombeii, a bivalve mollusc of nutritive and economic importance, with the last purpose of determining hazards for human health or for the export business of this product. Also, as a mean to evaluated the impact of the anthropic influence in the total levels of Hg in the organisms, the concentration of this element was measured in the chemist effluent of Oxy Chile Industry, which contributes to Hg drainage in the area. Fifteen samples of pedal muscle form T. dombeii were analyzed, collected in an area of the coast trimmings of San Vicente Bay (Chile, VIII Region) between January and December of 1991. The analytical method used for determining total Hg concentration, was atomic absorption spectrophotometry by cold vapor with a previous liofilization and acid digestion of the samples. Results indicated high concentrations of total Hg in the samples, without overcoming the national and international standards. Likewise, an important influence of environment in the levels of this element was found
