Avaliação da contaminação por elementos metálicos dos sedimentos do Estuário Santos - São Vicente

Abstract: Recebido em 4/7/06; aceito em 25/5/07; publicado na web em 3/12/07 ASSESSMENT OF METALLIC ELEMENT CONTAMINATION IN SEDIMENTS FROM THE SANTOS -SÃO VICENTE ESTUARINE SYSTEM.Three approaches were applied to evaluate metal contamination in 41 sediment samples from the SantosSão Vicente Estuarine System: normalization to Al, statistical analysis and sediment quality guidelines (SQGs). The results showed increases in the concentrations of Zn, Ni, Pb, Cd, Cr and Hg, which seemed to be associated with human activities… Show more

“…High levels of contamination have been reported for the sediment of the Santos region (CETESB, 2001;HORTELLANI et al 2008), including of that by heavy metals, which can interfere with many metabolic processes, preventing the full development of the plant (SIEDLECKA, 1995). On this basis, it is possible to attribute the poor development of some mangrove stands in the Santos region to stressors of anthropogenic origin that overlap with the natural forcings, as reported by OLIVER AND LARSON (1990).…”

“…6 Since sediments are transported by rivers to other bodies of water or the sea, analyses of sediments are useful for tracking and managing the control of contaminant dispersal routes. 7 Most of the contaminants that enter aquatic systems accumulate in the bottom sediment. As such, sediments are the ultimate destination for all processes occurring in the air, water and soil, with the ability to accumulate low concentrations of the elements present in water.…”

“…Importantes fontes de poluição para a região de estudo no Ponto 1 e no Ponto 2 são provenientes das atividades do complexo industrial de Cubatão, com o despejo irregular de resíduos sólidos industriais, dragagens do canal do porto e atividades portuárias (Hortellani et al, 2008). Adicionalmente a descarga de esgoto doméstico de Santos, São Vicente e Cubatão, o emissário submarino, localizado na orla de Santos, e os aterros sanitários (lixão), representam ainda uma substancial contribuição para a degradação dos Estuários de Santos e São Vicente podendo levar à eutrofização do ambiente aquático e o comprometimento da qualidade das águas para atividades de lazer com contato direto na orla marítima.…”
