Zusammenfassung

Concentrations of Al, Co, Cr, Cu, Fe, Mn, Ni, Pb, Ti, and Zn in sediments from San Pedro River were deter-mined to assess the anthropogenic effects. Temporal and spatial variation studies of metal concentrations allowed to identify aquaculture activities as the main metals source. Additionally, Mn was also related with a wastewater treatment plant and Pb with the use of leaded additives in gasolines and its banishment after 2001. Nevertheless, San Pedro River can be considered, in general, as a minor contaminated area, although sampling stations related with aquaculture activities showed a moderate pollution by Cu, Co and Ni. In spite of this, metal concentrations in sediments from San Pedro River presented a low risk for the biota. Only Ni and Cr concentrations were above the probable effect range within which adverse effects frequently occur. In fact, a poor chemical status of San Pedro River was observed for these elements.
