NASCIMENTO, Silvia Cremonez; HYPOLITO, Raphael e RIBEIRO, André Afonso. Availability of heavy metals in landfill of stainless steel. Eng. Sanit. Ambient. [online]. 2006, vol.11, n.3, pp. 196-202. ISSN 1413-4152. http://dx.doi.org/10.1590/S1413-41522006000300002.
This study was conducted by the detailed survey of the polluting source. Several samples of superficial and groundwater, effluents and industrial waste associated to the Industrial Landfill were collected. The results allowed to understand that the heavy metals behavior are strongly dependent on the physic chemical parameters as pH and Eh. High manganese and lead concentrations have been found, mainly in groundwater, demonstrating the great ions mobility, indicating theirs direct action in the pollutant process. Systematic monitoring of the polluting agents is recommended, alerting for the risk of bioaccumulation in the trophic web.
