SISINNO, Cristina L. S.. Non-inert industrial solid waste disposal in landfill dumps: evaluation of toxicity and implications for the environment and human health. Cad. Saúde Pública [online]. 2003, vol.19, n.2, pp. 369-374. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2003000200003.
According to Brazilian recommended technical procedures (mainly NBR 10,004), solid waste must be previously classified in order to be disposed of adequately. Non-inert industrial solid waste is being dumped in landfill areas, most of which operate inefficiently and are located near the population and important ecosystems. In order to evaluate the potential toxicity of solid waste produced by various types of industries, 21 samples were analyzed according to NBR 10,004 procedures. Of these, 18 were classified as non-inert solid waste. The main substances contributing to the classification of these samples as non-inert waste were: aluminum, iron, manganese, phenol, and surfactants. Aluminum, manganese, and phenol are the main toxicologically relevant substances for human and environmental health because they can alter the quality of groundwater situated under solid waste disposal areas.
