Cu, Pb AND Zn DISTRIBUTION IN NEARSHORE WATERS IN SAN JORGE BAY, NORTHERN CHILE

An extensive spatial survey metal content to study the spatial distribution of Cu, Pb and Zn concentration in nearshore waters of San Jorge Bay, along the coast of Antofagasta City, Chile was carried out located near the Atacama desert, which represent the largest populated urban settlement in north...
