Sedimentos de fondo, Tapiracuai, Cuarepoti, contaminantes, serie 3d, Corteza superior, valores de referencia en sedimentosResumen
Los sedimentos de fondo de los cuerpos de agua constituyen un reservorio para los cationes metálicos, moléculas y otros productos que a lo largo de lapsos, cortos o largos, pueden constituirse en contaminantes, con efectos deletéreos para la biota; el conocimiento de su contenido es pues muy importante. En este trabajo se investigan en los sedimentos de los arroyos Tapiracuai y Cuarepoti los tenores de elementos de la serie 3d que por la presencia/acción de electrones desapareados pueden originar reacciones de radicales libres, así como otros tales como el Cd y el Pb de conocida toxicidad. Los valores registrados son más bien bajos. En el examen de sus posibles efectos indeseables, se utilizan con fines de comparación y análisis, los diagramas multielementales (aracnogramas) referidos a los valores recomendados para la corteza superior así como a los valores guías de calidad de sedimentos. Los mismos indican la actual ausencia de riesgo potencial debido a tales elementos; señalan así mismo su utilidad para inferir expeditivamente, la existencia de niveles de efectos indeseables para la biota.
