CHEMICAL ELEMENTS ANALYSIS OF THE SOIL AT AN URBANIZATION GRADIENT IN THE ATLANTIC FOREST

ABSTRACT The Atlantic Forest is home to the largest urban centers in Brazil, which modify various aspects of the natural quality of this forest. Soil chemical elements from three different sites in the Atlantic Forest in the state of Rio de Janeiro were analyzed: (1) the best-preserved remnant of Atlantic Forest in the state; (2) the largest urban forest in the world; and (3) an arboretum along the main vehicle route in the second-largest city in Brazil. Energy dispersive X-ray fluorescence (EDXRF) analysis detected sixteen chemical elements including nutrient components and potentially toxic elements. The urban soil had a higher concentration of heavy metals. There was a significant concentration gradient of copper and lead from the urban site to the furthest forest site. We emphasize that the results indicate potential negative consequences for the conservation of forests and wildlife of state of Rio de Janeiro.
