    MARINE ENVIRONMENTAL-IMPACT DUE TO MINING ACTIVITIES OF EL-SALVADOR COPPER MINE, CHILE
    (1978) CASTILLA, JC; NEALLER, E
    Marine environmental impact as a result of Cu mine tailing dumping in the sea is studied at Chanaral (North Chile). These dumpings, from the Cu mine El Salvador, hindered harbor activities, caused geomorphological coastal modifications and seriously affected marine coastal ecosystems and recreational activities. At the old dumping site, Chanaral Bay (1938-1974), nearly 150 million tons of fine sediments were accumulated. Tailing discharges at the new dumping site, Caleta Palito, about 8 km north of Chanaral Bay are accumulating approximately at the rate of 25,000 tons of fine sediments/day, plus unknown quantities of chemicals (Cu, As, CN-). From Jan., 1975-July, 1976, this site received over 13 million tons of sediments, which caused deterioration of the marine coastal environment, reduction in light penetration and high mortalities among marine invertebrates, fishes and algae.
