“…The wastewater discharged from industrial sources into the surrounding rivers which runs into the Laizhou Bay could be responsible for this [18], [19], [20]. It has been reported that the deposition of fine grained materials and organic matter physically controls the abundance and distribution of metals in sediments [51]. The concentrations of Cu, Ni, Pb, and Zn appeared to be influenced by both the sediment grain size composition and the amount of organic matter; the concentration of Cr appeared to be more influenced by the sediment grain size composition than by the amount of organic matter; the concentration of Cd appeared to be influenced by neither the sediment grain size composition nor the amount of organic matter, perhaps because it is a typical anthropogenic element.…”

The total concentrations and chemical forms of heavy metals (Cd, Cr, Cu, Ni, Pb and Zn) in the surface sediments of the Laizhou Bay and the surrounding marine area of the Zhangzi Island (hereafter referred to as Zhangzi Island for short) were obtained and multiple indices and guidelines were applied to assess their contamination and ecological risks. The sedimentary conditions were fine in both of the two studied areas according to the marine sediment quality of China. Whereas the probable effects level guideline suggested that Ni might cause adverse biological effects to occur frequently in some sites. All indices used suggested that Cd posed the highest environmental risk in both the Laizhou Bay and the Zhangzi Island, though Cd may unlikely be harmful to human and ecological health due to the very low total concentrations. The enrichment factor (EF) showed that a substantial portion of Cr was delivered from anthropogenic sources, whereas the risk assessment code (RAC) indicated that most Cr was in an inactive state that it may not have any adverse effect either. Moreover, the results of EF and geoaccumulation index were consistent with the trend of the total metal concentrations except for Cd, while the results of RAC and potential ecological risk factor did not follow the same trend of their corresponding total metal concentrations. We also evaluated the effects of using different indices to assess the environmental impact of these heavy metals.

“…These authors reported Cr concentrations of 25.2 µg/g and 7.7 µg/g, respectively. Lacerda et al (1987) observed Cu values of 38.8 µg/g for Sepetiba Bay, Gomes et al (2009) of 31.9 µg/g for the Eastern sector of Sepetiba Bay and Freret-Meurer et al (2010), of 11.64 µg/g for Ribeira Bay. The values reported for Cu in these studies are lower than that recorded in the Western Sector do Sepetiba Bay (in those survey, 62 µg/g).…”

“…Average values of essential trace elemental concentrations (As, Cr, Cu, Mn, Zn, Al and Fe) in the analyzed samples were compared with values considered natural obtained through core analyses and in surface sediments in areas under reduced anthropogenic influence, such as Praia do Sul and Ribeira Bay, adjacent to Ilha Grande Bay (Silva-Filho et al, 1996;DePaula and Mozeto, 2001;Wasserman et al, 2001;Marques Jr. et al, 2006;Gomes et al, 2009). This comparison allowed to verify that in the Western sector of Sepetiba Bay these elements concentrations were above the local background values.…”

“…The Mercantile Company Ingá (Fig. 1), disabled in 2008, was one of the industries that most contributed to the addition of contaminants in Sepetiba Bay, especially Cd and Zn (Gomes et al, 2009). Its installation occurred in the decade of 60, in the region of Madeira Island, in the Itaguaí town, beginning the electroplating process and evolving to zinc processing in 1966, and later, in 1974, for the processing of cadmium (Barcellos, 1995).…”

Evaluation of the Environmental State of the Western Sector of Sepetiba Bay (Se Brazil): Trace Metal Contamination

et al. 2019

Sepetiba Bay located in Rio de Janeiro State (RJ), Southeast Brazil, is a region under heavy influence of seaports and mining. This feature puts at risk the quality of the local water system, especially due to the deposition of trace metals on the sediments. This work aimed to report the values of total concentrations of Ag, As, Cd, Co, Cr, Cu, Li, Mn, Ni, Pb, Sr, Zn and Hg obtained in bottom surface sediments collected in Nov/2010 in the Western sector of Sepetiba Bay, through the Plasma Spectrometer (ICP-OES). The average concentrations of Ag (0.40 µg/g), Cd (0.76 µg/g), Cu (62.59 µg/g), Li (43.29 µg/g), Ni (16.65 µg/g), Pb (20.08 µg/g), Sr (389.64 µg/g) and Zn (184.2 µg/g) exceeded the limits allowed by Brazilian legislation, and are, in addition, above the natural values found in Ribeira Bay (RJ), the considered control region. It is necessary to monitor this area, due to its economic and environmental importance. AVALIAÇÃO DO ESTADO AMBIENTAL DO SETOR OCIDENTAL DA BAÍA DE SEPETIBA (SE BRASIL): CONTAMINAÇÃO POR METAIS TRACEResumoA Baía de Sepetiba localizada no Estado do Rio de Janeiro (RJ), sudeste do Brasil, é uma região sob forte influência de portos marítimos e mineração. Esta característica coloca em risco a qualidade do sistema de água local, especialmente devido à deposição de metais traço nos sedimentos. Este trabalho tem como objetivo reportar os valores das concentrações totais de Ag, As, Cd, Co, Cr, Cu, Hg, Li, Mn, Ni, Pb, Sr, U e Zn obtidos em sedimentos de superfície de fundo coletados em Nov / 2010 no Setor Oeste da Baía de Sepetiba, através do Espectrômetro de Plasma (ICP-OES). As concentrações médias de Ag (0,40 µg / g), Cd (0,76 µg / g), Cu (62,59 µg / g), Li (43,29 µg / g), Ni (16,65 µg / g), Pb (20,08 µg / g ), Sr (389,64 µg / g) e Zn (184,2 µg / g) ultrapassaram os limites permitidos pela legislação brasileira, e estão, além disso, acima dos valores naturais encontrados na Baía da Ribeira (RJ), a região de controle considerada. É necessário monitorar esta área, devido à sua importância econômica e ambiental. Palavras-chave: Total Trace Metals. Sedimentos Litoral. Contaminação

“…Estima-se que ela tenha descarregado cerca de 24 ton ano -1 de cádmio e 3660 ton ano -1 de zinco para a Baía de Sepetiba até o fechamento de sua planta industrial, em 1997, sugerindo que essa tenha sido a principal fonte de contaminação deste corpo hídrico e de sua bacia. Tais dados vêm ao encontro aos apresentados por Gomes et al, 11 que mostraram que o fluxo de Cd e de Zn a partir do Rio Guandu para a baía nos últimos 50 anos aumentou em mais de uma ordem de magnitude (Cd: 1,6 x 10 -3 para 2,2 x 10 -2 g m -2 ano -1 ;…”

River Cabuçu-Piraquê, a tributary of Sepetiba Bay, has a history of pollution for decades, but without a systematic study of the origins and fate of trace elements such as cadmium and zinc, in its environmental compartments. The bioaccumulation of these elements can cause serious damage to the biota of mangroves in its estuary, and to human consumers of local fisheries. In this study, it was evaluated the current state of contamination of water and sediment from that river by means of various parameters (concentration of dissolved oxygen and ammonium and phosphate ions, among others), as well as the occurrence of the transport and accumulation of these metals in the estuary´s sediment fraction brought by the bay waters during high tides. Concentrations of cadmium and zinc above those considered safe by Brazilian law were found both in the fine fraction (< 63 µm) of sediment, averages of 5 and 1351 mg kg-1 , respectively, and at high tide waters, 0.09 and 0.31 mg dm-3 , respectively. Both metals were found only in the most bioavailable operating fractions of waters, while sediment average values of 92 % were found for Cd, and 97 % for Zn at same fractions. From the concentrations of these metals in water from the saline wedge generated by the bay, it was possible to infer such an influx into the estuary from the material present in the bay waters, and this transport process may be shipping a major contributor to contamination of the local mangroves.
