“…As previous mentioned, metals in eggs also came from females, being transferred during eggs production (Beltrame et al 2010;Simonetti et al 2012;Lavradas et al 2014). The hepatopancreas plays an important role in this process, due to the storage of lipid reserves (Kyomo 1988).…”

“…In another study, Simonetti et al (2012) found increase of one order of magnitude of Cu in crab female (N. granulata) in comparison to eggs in a moderate polluted estuary. Lavradas et al (2014) found higher concentrations of Cu and Cd in hepatopancreas of Callinects sp. females in comparison to eggs while Cd and Zn were higher in eggs compared to the hepatopancreas of females.…”

“…Previous works with South Atlantic crabs Neohelice granulata (Beltrame et al 2010;Simonetti et al 2012) and Callinectes sp. (Lavradas et al 2014) proposed transfer of trace metal between females and eggs and environment and eggs. Unfortunately, there was few data about crab eggs and larvae contamination, including in different developmental stages.…”

The mangrove crab Ucides cordatus is widespread in the Brazilian coast, which has an important role in nutrient cycling. This species reproduces in summer and females carry eggs about a month, when they maintain contact with water and sediments. It remains unclear if trace metals can be absorbed or adsorbed by the eggs during development. The present study aims to investigate, for the first time, trace metal concentrations in ovigerous female tissues and eggs of U. cordatus in two areas with different metal pollution levels in the Southeastern Brazil. Samples were collected in two different mangroves, Guanabara Bay (GB) highly polluted environment and Paraíba do Sul River (PSR). In both populations, we observed significant increase of V, Cr, and Mn concentrations along eggs maturation. The higher metals averages were found in PSR population. This trend was reported since the 1990s and lower concentrations in GB marine organisms were attributed to reducing conditions, high organic load, and the presence of sulfide ions. These conditions restrict the bioavailability of metals in the bay, with exception of Mn. No significant differences were observed in gills and muscles. In both populations of the present study, V, Zn, As, and Pb were higher in eggs of initial stage, whereas Mn, Ni, Cu, and Cd were higher in hepatopancreas. Beside this, V, Cr, Mn, As, and Pb showed an increase concerning egg development. Thus, V, As, and Pb in eggs come from two sources previous discussed: females and environment. Zinc came mainly from females due to essential function. Those new information should be considered as one of the mechanisms of trace metal transfer to the trophic chain, between benthonic and pelagic environment.

“…These effects include metabolism depression, diseases and genotoxic damage, and as a result fishes are important bioindicators of metal contamination (Carrola et al, 2014;Lavradas et al 2014;Ahmed et al, 2015;Gusso-Choueri et al, 2016;Gu et al, 2018). Contamination effects can be immediately detected by sensitive biochemical indicators that are efficient applied to environmental monitoring programs (Van Der Oost, Beyer & Vermeulen, 2003;Hauser-Davis, Campos & Ziolli, 2012).…”

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.

“…A espectrofotometria na região UV-Vis é considerada uma técnica analítica robusta e de baixo custo apresentando, também, alta sensibilidade e podendo ser empregada para os mais variados tipos de amostras e/ou análilses (Rocha e Teixeira, 2004). Dessa forma, essa técnica vem sendo bastante utilizada na quantificação de proteínas e atividades enzimáticas, sendo assim uma ferramenta importante nos estudos de contaminação ambiental (Bastos et al, 2013;Lavradas et al, 2014).…”
