Prospecção de plantas para fitorremediar áreas de mineração contaminadas com metais pesados na região de Caçapava do Sul (RS)

Abstract

The mining activity presents importance for the economic growth of Brazil. More specifically, in the state of Rio Grande do Sul, there are several mining companies, some of which are focused on the exploitation of metallic minerals, which are raw materials used in metallurgical processes. Copper mining in Caçapava do Sul-RS lasted about 100 years and was highlighted for supplying the national consumption of this metal. However, this type of anthropic activity becomes a problem for society by exposing heavy metals to soil and water without proper intervention causing environmental contamination. Thus, this project has the objective of identifying plants capable of phytoremediate mining tailing areas contaminated by heavy metals, in Camaquã Mines, Caçapava do Sul-RS. The methodology to be used consists of ICP analysis of heavy metals found in tailings and plants in the mining region of Camaquã Mines. The results showing there are adapted plants with phytoremediation potential in the area in question, thus, studies of the application of phytoremediation in areas contaminated by mining will assist in the technical knowledge to solve the impacts of the mining activities whose wastes are heavy metals.
