PRELIMINARY PHYSICAL CHEMICAL CHARACTERIZATION OF RIVER WATERS AND SEDIMENTS AFFECTED BY COPPER MINING ACTIVITY IN CENTRAL CHILE: APPLICATION OF MULTIVARIATE ANALYSIS

The concentration of trace elements and other analytes of environmental interest was determined in waters and sediments of the Coya and Cachapoal rivers (VI Region, Central Chile), which corresponds to a location highly polluted by copper mining activity. Analysis showed the highest pollution at the...
