The tropical coastal lagoon of San Ignacio-Navachiste-Macacupe, receive a remarcable inputs of antropogenic remains derived from the main catchement agricultural area in Mexico. In order to assess their influence over the ecosystem, trace elements including rare earths were determined in suspended particulate matter (SPM). Polycarbonate filters were used for seawater filtration, previously washed and weighted. They were totally digested and the determination was using an ICP-MS. Results on metal concentratios showed values of Cd, Co, Cu, Mn, Pb and U including rare earth elements (REE), severely enriched if they are compard with the Earth´s crust average, and with NASC. The spatial distributions showed puntual enrichments of metals. The highest value for potentially toxic elements in the SPM are anomalous and have significant correlation with the catchment agricultural, aquicultural, urban effluents.
Palabras clave: San Ignacio-Navachiste-Macacupe; tropical coastal lagoon; potentially toxic elements
