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 over 50 years mine tailings were dumped on the coast, causing severe damage in the ecosystem. To evaluate the effects on terrestrial biota, we analyzed the concentration of cadmium and lead in tissues of Turkey Vulture (Cathartes aura). The results indicate that accumulation of cadmium in kidney was 10.31 &amp;#956;g/g (SD 8.00, range 0.27 to 20.73 &amp;#956;g/g) while in the liver was 5.24 &amp;#956;g/g (SD 8.00, range 0.49 to 19.70). There values are very...
