Abstract

Temperature, salinity, turbidity, total suspended solids (TSS), pH, and dissolved oxygen were measured in the surface water of the Pom-Atasta Lagoon at 15 stations during 5 sampling events fi om September 1996-May 1997. Concentrations of Cu, Cd, Ni, Zn, Pb, Cr, Ag, Fe, Co, and Ba were also determined in the water and sediments at 15 stations during the study period. The values of salinity, turbidity, and TSS were related to the inputs of river water into the lagoon. Metals in the water and sediments showed no spatial variation. Seasonality in the concentrations of Cu, Zn, Ag, and Ba in the water was found and may be related to the resuspension of sediments in the lagoon. The concentrations of metals in sediments did not give significant seasonal variation. Metals in sediments were not correlated with the iron, suggesting an anthropogenic source of metals in the Pom-Atasta Lagoon. The concentrations of dissolved Pb were above the value recommended by the National Water Commission of Mexico. (C) 1999 Elsevier Science Ltd.
