Cadmium and Lead content in Liver and Kidney tissues of Wild Turkey Vulture Cathartes aura (Linneo, 1758) from Chañaral, Atacama desert, Chile

The Atacama region, Chile, presents one of the highest levels of mining exploitation of the country, which leads to high levels of contamination from mine tailings and other related environmental liabilities. One of the most complex situations occurred in the Chañaral city, north of Chile, where for...
