SISINNO, Cristina L. S.; PEREIRA NETTO, Annibal D.; REGO, Eliane Cristina P. do  and  LIMA, Guilherme dos Santos V.. Polycyclic aromatic hydrocarbons in industrial solid waste: a preliminary evaluation of the potential risk of environmental and human contamination in waste disposal areas. Cad. Saúde Pública [online]. 2003, vol.19, n.2, pp.671-676. ISSN 1678-4464.

Proper solid waste disposal is important to avoid human and environmental contamination. The NBR 10,004 Waste Classification lists several polycyclic aromatic hydrocarbons (PAHs) and indicates that the presence of at least one PAH in a waste sample is enough to classify it as hazardous. The aim of this study was a preliminary evaluation of PAHs in solid waste samples from selected industries to obtain a preliminary overview of their potential for contamination in case of improper disposal. One or more PAHs listed in NBR 10,004 (benzo[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene, benzo[k]fluoranthene, indene[1,2,3-c,d]pyrene, chrysene, or fluoranthene) were found in all samples, thus leading to their classification as hazardous waste. Our results showed that toxicologically relevant PAHs were found in all the samples, indicating that their final disposal must be performed in appropriate areas in order to minimize human health risks and environmental contamination from waste disposal areas.
