Phytoremediation in Soil Contaminated with Mining Waste in Argentina
Short Introductive summary
Mining waste causes a plume of pollution generated by the release of metal(loid)s at a very acidic pH through erosion, runoff and leaching processes. This generates great concern due to the risks they present for human and environmental health. The aim of this study was restore an arid environment degraded by mining environmental liabilities through the implementation of phytoremediation strategies using four native species. The bioaccumulation values recorded in the field and under controlled conditions showed a higher bioaccumulation of Cu for the four species. The results obtained were scaled up to field conditions. Two in situ plots were installed and the four native species were transplanted. After three years of exposure of the four native phytoremediation species, not only the survival of the native species was achieved, with values between 67-83% survival. Regarding the growth pattern, these species presented a growth of 69% L. cuneifolia, 33% P. tetracantha, 86% P. flexuosa and 42% B. retama in relation to the initial height. The application of soil amendments not only increased the pH value and nutrient content, reaching optimal values for plant growth, but also decrease
