Recovery of the biodiversity of na area of Atlantic Rainforest contaminated by heavy metals: a proposal for bioremediation

Abstract

The purpose of this project is the development of bioremediation strategies and recomposition of a contaminated (heavy metals) Atlantic Forest using methalophytes plants microorganisms associated with rysosphere. The area choose for this study -Nagib Najar Park ¬is located in hydrographic basin of Tietê river, one of the most complex of in Brazil, due the forest reminiscent that exhibit the major taxes of endemism in Brazil Biota. Therefore, this work to allow, at the end, the development of strategies for biorecuperation, not only for this area, but also another's sites with similar problems. In the first step, the better experimental area that represents the contamination gradient will be choose and different samples from soil Park will be physicochemical analyzed. The fauna, flora and microbiote biodiversity will be evaluated and, the results compared to the no impacted Atlantic Forest, or with another's studies realized on this biome. Also, the bioaccumulation in fauna and flora of the heavy metals will be quantified, allowing choose the native plants that could be used in depolution of the contaminated Park area. Finally, this project will allow the organization of a data bank containing all results obtained by the multidisciplinary equip and, also a new strategy for site monitoring. This study offers opportunities to surgiment of the news researches to this region, prioritary in the programs conservation, mainly due to mananciales richest. (AU)
