Total concentrations of trace elements can provide fundamental information on the sediment contamination levels of the pollution indexes and the quality guidelines for sediment risk assessment. However, this information alone is insufficient to under

Mining is one of the most important industrial activities in Chile and there is growing concern on pollution by some mining and metallurgical processes. We have studied the contents of heavy metals in sediments from three river basins in Chile. Sampl
