Caracterização da contaminação por metais pesados em área de mangüezal, Município de Santos (SP)

Abstract: REsuMOO presente trabalho teve como objetivo caracterizar a contaminação do solo e das águas subterrâneas e superficiais por metais pesados em uma área de manguezal em santos (sP), utilizada como local de descarte de resíduos das atividades portuárias por mais de 50 anos. Análises químicas do solo e das águas coletados no local de estudo indicaram que as concentrações de íons de metais pesados (Pb, Zn, Cu, Ni) encontram-se acima dos valores de referência de qualidade da CETEsB. O elevado teor de matéria orgâni… Show more

“…These values were much lower than the range from 34.71 to 650.90 mg dm -3 reported by Fortunato et al (2012), who studied mangrove areas used as areas of disposal of port activity residues. In addition, the values of Zn observed in the studied soil after the application of LFL are not worrying, since they are inferior to the limit of 300 mg dm -3 for the prevention of toxicity (Brasil, 2009).…”

“…Comparing the results of the present study with those of Fortunato et al (2012), Cu contents were much lower than the range of 12.89 to 828.67 mg dm -3 observed in mangroves contaminated with port wastes. According to the CONAMA resolution n o 420/2009 (Brasil, 2009), the Cu contents observed in the studied soil after the application of LFL do not represent environmental risk, because they are much lower than the value of 60 mg dm -3 , established for the prevention of toxicity.…”

“…These landfills, scattered around the estuary, consist of legal and illegal industrial and domestic wastes disposal sites and were installed along the mid and late 20 th century. They still represent a considerable source of contamination to the internal areas of the estuarine system (Fortunato et al, 2012;Schepis et al, 2016).…”

“…Durante esse período, o lixo do município foi descartado no lixão, sem tratamento, numa condição agravada devido à importância do manguezal e pequena profundidade do lençol freático. Sabe-se que lixões representam fontes de uma extensa gama de poluentes para solos, águas superficiais e subterrâneas, como por exemplo, mercúrio, cobre, manganês, arsênio, cianeto, compostos fenólicos, hidrocarbonetos policíclicos aromáticos (HPA), dioxinas e furanos, entre outros (Fortunato et al, 2012;Lamparelli et al, 2001).…”
