“…Several trace metals with high concentrations in fish muscle including Cu, Zn, Cd, and Hg were also observed at high concentrations in the mine tailings deposited in the estuary (Gabriel et al, 2020). The transfer of bioavailable metals from contaminated sediments in coastal ecosystems has been widely reported (Zhu et al, 2015;Hauser-Davis et al, 2016;Gusso-Choueri et al, 2018, Mason et al, 2019 and support that tailings in the Rio Doce estuary were the source of the observed sublethal effects and statistical correlations observed between metal and protein concentrations in fish.…”

AbstractThe Rio Doce estuary in Brazil was impacted by the deposition of mine tailings caused by the collapse of a mining dam in 2015. Since the disaster, the estuary is experiencing chronic trace metal contamination effects, but potential trace metal accumulation in fishes has not been reported. Trace metals in aquatic ecosystems pose severe threats to the aquatic biota, so we hypothesized that the accumulation of trace metals in estuarine sediments nearly two years after the disaster would cause contaminant bioaccumulation, resulting in the biosynthesis of metal-responsive proteins in fishes. We determined trace metal concentrations in sediment samples, metal concentrations, and quantified stress protein concentrations in the liver and muscle tissue of five different fish species in the estuary. Our results revealed high concentrations of trace metals in estuarine sediments when compared to published baseline values for this estuary. The demersal fish species Cathorops spixii and Genidens genidens had the highest Hg, As, Se, Cr, and Mn concentrations in both hepatic and muscle tissues. Metal bioaccumulation in fish was statistically correlated with the biosynthesis of metallothionein and reduced glutathione in both fish liver and muscle tissue. The trace metals detected in fish tissues resemble those in the contaminated sediments present at the estuary at the time of this study and were also significantly correlated to protein levels. Trace metals in fish muscle were above the maximum permissible limits for human consumption, suggesting potential human health risks that require further determination. Our study supports the high biogeochemical mobility of trace metals between contaminated sediments and local biota in estuarine ecosystems.

“…This is a key advantage of the use of these biomarkers, as most contaminated areas lack baseline studies as in the studied estuary. Thus, the observed biomarker responses are an additional support for the indication of chronic trace metal contamination effects in this ecosystem (Gusso-Choueri et al, 2018;Bernardino et al 2019).…”

“…Arsenic, for example, at very small doses is a useful element because it seems to improve the activities of some CNS neurotransmitters. However, it is also a toxic and carcinogenic metal, it also has a genotoxic mechanism, therefore it increases cell proliferation with the release of growth factors, modifies DNA repair and finally participates in oxidative stress with the production of oxygen free radicals.…”

Faro Lake is a coastal meromictic lagoon with singular characteristics in the Mediterranean (Messina, Sicily - Italy). It is part of the Natural Oriented Reserve of Capo Peloro (38° 15' 57″ N; 15° 37' 50″ E). In this area, traditional mollusc farming activity persists, producing 'autochthonous' mussels. This study reports of the Mytilus galloprovincialis haemolymph chemical profile and water variables determination of 1 year-lasted survey (April 2016 - March 2017). The determinations of electrolytes (Na , Cl , K , Ca , Mg , P inorganic) and heavy metals in both Faro lake water and haemolymph have been carried out. Heavy metals are elements with high density and are quite toxic in low concentrations, such as Aluminum (Al), Arsenic (As), Cobalt (Co), Chrome (Cr), Copper (Cu), Iron (Fe), Magnesium (Mg), Manganese (Mn), Lead (Pb), Tin (Sn), Zinc (Zn). Heavy metals toxicity depends, principally, on bioaccumulation processes. M. galloprovincialis is a good bio-indicator, ideal for assess levels of environmental pollution thanks to its biological, ecological and physiological characteristics. The results of this study showed a typical fluctuation range in haemolymph and water parameters, related to the water ones; chemical-physical parameters affected the ions (electrolytes and metals) levels in some period of the year. The study reports the interactions between biotic (Mytilus galloprovincialis) and abiotic (water parameters) components of Faro Lake, and creates reference data for further future study on the same area or on similar ones.

“…Guimarães e Sígolo (2008b) observaram altos teores de metais (Zn, Cu e Pb) próximo a este centro urbano e afirmam que os baixos valores de pH e do potencial redox obtidos pela pesquisa, possivelmente, estejam contribuindo para liberação desses metais (mobilidade). Este fato pode ser a causa da aumentada biodisponibilidade na região, o que consequentemente aumentam as probabilidades destes elementos serem retidos pelos organismos aquáticos e participarem da cadeia alimentar SÍGOLO, 2008;BORAN;ALTINOK, 2010;GUSSO-CHOUERI et al, 2018).…”

“…Estes processos podem fazer com que estes elementos fiquem disponíveis para a biota (MALUF, 2009;BORAN;ALTINOK, 2010). Investigações com a biota local revelam a alta biodisponibilidade de metais em ambas as regiões, por meio da incorporação destes elementos por diferentes espécies de moluscos (MACHADO et al, 2002;SÍGOLO, 2008a) e peixes (CASTRO, 2012;FERNANDEZ et al, 2014;GUSSO-CHOUERI et al, 2018).…”

O Complexo Estuarino-Lagunar de Iguape-Cananéia (CELIC) apresenta condições ambientais distintas entre suas porções Norte e Sul e sofre com diferentes pressões antrópicas. Este estudo avaliou a variação espacial e temporal da biodisponibilidade dos metais Fe, Zn, Mn, Co, Cu, Cr, Cd, Pb and Ni, nos sedimentos em 8 pontos do CELIC em 2 períodos de 2013. A avaliação da biodisponibilidade dos metais deu-se através do método da extração simultânea de íons metálicos e sulfetos volatizados por acidificação (SEM/SVA). Foi vista ampla variabilidade espacial e temporal nos parâmetros analisados, onde a média dos metais fortemente biodisponíveis deu-se na ordem de Fe>Mn>Zn>Pb>Cu. Todos os pontos apresentaram razão SEM/SVA > 1 para os íons metálicos Pb, Cd, Ni, Cu e Zn, com maior toxicidade dos sedimentos a Norte, sugerindo a biodisponibilidade desses metais e destacando o potencial destes sedimentos de causar efeitos adversos à biota local. Estes resultados salientam as influências do aporte de resíduos urbanos, agrícolas e de atividades mineradoras pretéritas ao sistema, advindos especialmente do Rio Ribeira de Iguape.
