FLUES, Marlene et al. Evaluation of the influence of a coal plant operation on metal and as concentrations in the soil of Figueira, PR-Brazil. Quím. Nova [online]. 2008, vol.31, n.1, pp.25-30. ISSN 0100-4042.

The aim of this work is to study metal and As concentrations in soil due to ash deposition from a coal plant at Figueira (PR), evaluating the macroelement (Al, Ca, Fe, Mg, Mn, Ti, V) and microelement (As, Cd, Co, Cr, Cu, Mo, Ni, Pb, Zn) concentrations in the soil around the coal plant. The plant operation caused a slight increase in the majority of the metal concentrations in the top soil close to the plant (up to 1 km) in the wind direction (NW). The elements As, Cd, Mo, Pb and Zn are considered likely soil pollutants, and As is considered the only critical element.

Keywords : metals; soil; coal plant.
