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...

Treated sewage sludge (Defective) has been identified to increase heavy metals in the soil which are in turn transferred to plants. In view of this, the study is aimed at assessing the effects of treated sewage sludge on the quality parameters of okra fruits. The randomized block design was employed in raising okra plants with three treatments (0t/ha, 10t/ha, and 20t/ha sewage sludge amendment) over a land area of 56.3m2. Soil analysis was used to determine the level of nitrogen, phosphorus, and potassium in the soil. After 2months, the okra fruits were harvested by cutting the pods off, slicing, oven drying, milling, and labeled correctly prior to laboratory analysis. The heavy metal content in the okra fruit were analysed using atomic absorption...

ABSTRACT This study was conducted in the River Panjkora, Pakistan, in order to assess the level of heavy metals accumulated in the liver, kidneys, gills and muscle tissues of three highly consumed fish species by the local community, Garra gotyla, Cyprinus carpio and Cyprinion watsoni. The heavy metals including manganese (Mn), iron (Fe), chromium (Cr), zinc (Zn), lead (Pb), cadmium (Cd) and nickel (Ni) were determined in the collected fish specimens through an atomic absorption spectrophotometer. Level of heavy metals significantly varied depending upon tissues type and fish species. Cyprinus carpio accumulated highest concentration of heavy metals, followed by Garra gotyla while Cyprinion watsoni accumulated least concentration of heavy metals. All the...
