Abstract	Maternal transfer is a notable contaminant source for elasmobranchs during the embryonic development. The maternal offloading of several compounds has been evaluated, especially concerning legacy contaminants. However, information on pharmaceuticals and personal care products (PPCPs) offload and, consequently, embryonic exposure in elasmobranchs is still unknown. Despite this, previous detection of PPCPs in pregnant females suggested the maternal offloading of these compounds in the Brazilian guitarfish Pseudobatos horkelii, yet progeny levels were not investigated. For this reason, our goal was to estimate and describe the maternal transfer of four PPCPs in P. horkelii. Diclofenac, methylparaben, octocrylene and triclosan were determined in liver and uterine content samples of five pregnant females using gas chromatography coupled to mass spectrometry. Diclofenac and methylparaben were detected in maternal and uterine content samples, whereas octocrylene and triclosan were only detected in maternal livers. This suggests that diclofenac and methylparaben are transferred to the offspring, at maximum transfer capacities of 27% and 6%, respectively. The lack of detection of other analytes in uterine content suggests that these contaminants might not be transferred. The concentrations observed for diclofenac and methylparaben are similar to those reported in adult elasmobranchs and teleosts, showing that embryos are exposed to considerable levels during their development. In addition, maternal diclofenac concentrations were not influenced by maternal size, suggesting that this species is continuously exposed in the studied area. These results are important for understanding the maternal offloading process and predicting PPCPs impacts throughout this species life cycle.

Abstract	Background: In 2015, Brazil had its most notorious ecological disaster due to an iron mine dam collapse. It was considered the world's largest environmental disaster associated with mining industry. The tailings composed mostly of iron ore and silica, but with high levels of heavy metals reached the Atlantic Ocean, through the Doce River, sixteen days after the rupture. The region where the mud ran into the ocean is an important nesting area for loggerhead turtles (Caretta caretta) in Brazil (Povoação, Espírito Santo state). The aim of this study is to evaluate the heavy metal effects on the health parameters of loggerhead turtles that nest in the exposed area (Povoação, Doce river estuary) and compare them with turtles from another coastal area that was not affected by the tailings (Praia do Forte, Bahia state). Methods: Animals’ health status was determined by a physical examination during which blood samples used to perform biochemical and hematological analysis were also obtained. Heavy metal concentrations were evaluated in the blood and carapace scutes. Results: Sea turtles from Povoação had a worse body condition with higher ectoparasitic and epibiont loads compared to Praia do Forte animals. They also showed eye lesions and more frequent fibropapillomatosis suggestive tumors. Several correlations between the contaminants and hematological and plasma biochemical analytes were found in loggerhead sea turtles from Povoação. Blood metal concentrations were distinct between nesting areas, with higher As, Cd, Cr, Fe, Pb, and Zn levels in animals from the affected area. In the carapace scute, the heavy metal levels were similar between sites. Conclusion: The occurrence of eye lesions, suggestive fibropapillomatosis tumors, worse body condition, higher ectoparasite count, greater epibiont loads, large number of correlations between health parameters and heavy metal levels, and higher levels of some metals in the blood of PV turtles indicates that the tailings could have a negative impact on the health and ...

Abstract: Cells rich in mitochondria were isolated from gills of the seawater clam Mesodesma mactroides, incubated in isosmotic saline solution (840 mOsmol/kg H2O), and exposed (3 h) to environmentally realistic Cu concentrations (nominally: 0, 5, 9 and 20 μg/L). ... ...

Abstract	Cells rich in mitochondria were isolated from gills of the seawater clam Mesodesma mactroides, incubated in isosmotic saline solution (840 mOsmol/kg H2O), and exposed (3 h) to environmentally realistic Cu concentrations (nominally: 0, 5, 9 and 20 μg/L). In cells exposed to 20 μg Cu/L, Cu accumulation, Na+ content reduction and carbonic anhydrase (CA) activity inhibition were observed, without significant changes in cell viability and Na+,K+-ATPase (NKA) activity. In the absence of Cu, cell viability and Cu content were reduced in hyposmotic media respect with the control, without changes in Na+ content and enzyme (CA and NKA) activities. In the presence of 5 or 9 μg/L Cu, cell Cu content was increased, especially at 670 mOsmol/kg H2O. Cell Na+ content and NKA activity were reduced after exposure to 20 μg/L Cu at 670 mOsmol/kg H2O. In turn, CA activity was dependent on Cu concentration, being significantly reduced in cells exposed to 9 and 20 μg/L Cu in both hyposmotic conditions. These findings indicate that Cu also negatively affects Na+ regulation in gill cells of the seawater clam M. mactroides, with Cu toxicity increasing at hyposmotic conditions. Also, they indicate that physiology is more important than water chemistry in predicting Cu toxicity in environments of changing salinity, pointing out CA activity as a potential biomarker of Cu exposure.

Abstract	Abstract Mass coral bleaching represents one of the greatest threats to coral reefs and has mainly been attributed to seawater warming. However, reduced water quality can also interact with warming to increase coral bleaching, but this interaction depends on nutrient ratios and forms. In particular, nitrate (NO3 −) enrichment reduces thermal tolerance while ammonium (NH4 +) enrichment tends to benefit coral health. The biochemical mechanisms underpinning the different bleaching responses of corals exposed to DIN enrichment still need to be investigated. Here, we demonstrated that the coral Stylophora pistillata underwent a severe oxidative stress condition and reduced aerobic scope when exposed to NO3 − enrichment combined with thermal stress. Such condition resulted in increased bleaching intensity compared to a low-nitrogen condition. On the contrary, NH4 + enrichment was able to amend the deleterious effects of thermal stress by favoring the oxidative status and energy metabolism of the coral holobiont. Overall, our results demonstrate that the opposite effects of nitrate and ammonium enrichment on coral bleaching are related to the effects on corals’ energy/redox status. As nitrate loading in coastal waters is predicted to significantly increase in the future due to agriculture and land-based pollution, there is the need for urgent management actions to prevent increases in nitrate levels in seawater. In addition, the maintenance of important fish stocks, which provide corals with recycled nitrogen such as ammonium, should be favoured.

Abstract	The emission of greenhouse gases has grown in unprecedented levels since the beginning of the industrial era. As a result, global climate changes, such as heightened global temperature and ocean acidification, are expected to negatively impact populations. Similarly, industrial and urban unsustainable development are also expected to impose local impacts of their own, such as environmental pollution with organic and inorganic chemicals. As an answer, biomarkers can be used in environmental programs to assess these impacts. These tools are based in the quantification of biochemical and cellular responses of target species that are known to respond in a sensitive and specific way to such stresses. In this context, carbonic anhydrase has shown to be a promising biomarker candidate for the assessment of global and local impacts in biomonitoring programs, especially in marine zones, such as coral reefs, considering the pivotal role of this enzyme in the calcification process. Therefore, the aim of this review is to show the recent advances in the carbonic anhydrase research and the reasons why it can be considered as a promising biomarker to be used for calcifying organisms.

Abstract	Coral reefs are subjected to climate change and are severely impacted by human activities, with copper (Cu) being a relevant physiological stressor for corals at local scale. The ecological relevance of parameters measured at biochemical or cellular level is now considered an extremely important feature in environmental studies, and can be used as early warning signs of environmental degradation. In this context, the effects of acute exposure (96 h) to Cu were assessed on the maximum photochemical efficiency of zooxanthellae (Fv/Fm) and on the activity of key enzymes [carbonic anhydrase (CA) and Ca-ATPase] involved in coral physiology using the scleractinian coral Mussismilia harttii as a biological model. Corals were exposed to different concentrations of dissolved Cu (4.6–19.4 μg/L) using two different experimental approaches: a laboratory closed system and a marine mesocosm system. Fv/Fm values and Ca - ATPase activity were not affect by exposure to Cu in any of the exposure systems. However, a significant reduction in CA activity was observed in corals exposed to 11.9 and 19.4 μg Cu/L in the laboratory and at all concentrations of Cu tested in the mesocosm system (4.6, 6.0 and 8.5 μg/L). Based on the sensitivity of this enzyme to the short period of exposure to sublethal concentrations of Cu in both experimental approaches, the present study suggests the use of CA activity as a potential biomarker to be used in biomarker-based environmental monitoring programs in coral reefs.

Abstract	O estuário da Lagoa dos Patos (Rio Grande do Sul, Brasil) possui aproximadamente 1.000 km2 de águas com pequena profundidade, alta produtividade primária e secundária e sedimentos arenosos ricos em organismos bentônicos, que servem como alimento para o camarão-rosa Farfantepenaeus paulensis. Vários estudos têm sido realizados com objetivo de desenvolver as atividades de cultivo de camarões em cercados como alternativa para os pescadores artesanais. O trabalho teve como objetivo analisar a sobrevivência e crescimento do camarão-rosa F. paulensis cultivado em cercados no estuário da Lagoa dos Patos. Dois cercados circulares foram construídos com área total de fundo de 3.100 m2. Na parte interna dos cercados de engorda (1 e 2) foram construídos berçários de 120 e 40 m2, onde foram estocados 23.250 e 18.083 juvenis com peso médio inicial de 0,18 e 0,16 g, respectivamente, obtidos a partir da reprodução em laboratório. Os camarões foram mantidos no berçário até atingir o peso necessário para serem cultivados nos cercados de engorda (0,35 g). Durante os 100 dias de cultivo, os camarões foram alimentados com rejeito de pesca em uma proporção de 70% de peixe e 30% de siri. No final do experimento, as sobrevivências foram 82,6 e 90,3% e os pesos finais, 9,05 e 7,35 g, nos cercados 1 e 2 respectivamente. Com isto, a biomassa final nos cercado 1 e 2 atingiram 173,76 e 119,99 kg, respectivamente. Os resultados obtidos evidenciam que o cultivo do camarão-rosa em cercados é uma alternativa viável para comunidade de pescadores no estuário da Lagoa dos Patos.

Abstract	In the present study, metal (As, Cd, Cu, Fe, Mn, Pb and Zn) accumulation and expression of genes involved in metal metabolism (metallothioneins, ATP7A and CTR1) were evaluated in gills and muscle of the fish Hyphessobrycon luetkenii living in the João Dias creek, a site historically (~1870–1996) contaminated with a metal mixture associated with copper mining (Minas do Camaquã, southern Brazil). Fish were collected in a metal impacted site of the João Dias creek and kept in a cage at this site (PP fish) or translocated to a non-metal impacted reach of this creek (PC fish). Gill metal concentrations and metallothionein gene expression were lower in PC fish than in PP fish at any experimental time (24, 48 and 72 h). In muscle, no significant changes were observed. These findings indicate that metal accumulated in gills of wild fish chronically exposed to the metal mixture are more easily excreted than those accumulated in the muscle. In this case, expression of gene encoding for metallothionein is shown to play a key role in the regulation of metal accumulation in gills of H. luetkenii living in an area historically contaminated with a metal mixture associated with copper mining.

Abstract	The early life stages of freshwater mussels are particularly sensitive to copper (Cu) contamination. We measured the acute toxicity, bioaccumulation, and sublethal effects of Cu in glochidia. In addition, we used radiolabeled Cu (â¶â´Cu) to examine the timeâdependent kinetics of uptake over 24âh. Uptake of â¶â´Cu by live and dead glochidia exposed to 0.11âÎ¼mol/L exhibited similar hyperbolic patterns over the first 40âmin, indicating an adsorptive phase independent of larval metabolism. Thereafter, uptake was linear with time, with a 10âfold lower bioaccumulation rate in live than in dead animals, representing a close to steady state of Cu regulation. In contrast, dead glochidia exhibited a progressively increasing uptake, possibly attributable to the fact that metalâbinding sites become more accessible. Mortality was strongly correlated with bioaccumulation (48âh); live glochidia exposed to Cu concentrations >0.27âÎ¼mol/L lost their regulatory ability and accumulated Cu to an even greater extent than dead animals. Exposure to Cu induced significant decreases in wholeâbody Naâº and MgÂ²âº concentrations; increases in reactive oxygen species concentration, lipid peroxidation, and protein carbonylation; and a decrease in antioxidant capacity against peroxyl radicals. Overall, these results clarify the patterns of Cu uptake and regulation, emphasize the importance of distinguishing between live and dead larvae, and indicate that toxicity is associated with Cu bioaccumulation, involving both ionoregulatory disturbance and oxidative stress.

Abstract	Biochemical biomarkers were evaluated in the barnacle Balanus improvisus (Crustacea: Cirripedia) sampled from both polluted and reference sites in the Patos Lagoon Estuary, Southern Brazil. During winter, higher glutathione S-transferase (GST) activity was recorded in the barnacles from the polluted sites, indicating environmental exposure to contaminants. Relatively low lipid peroxide levels (LPO) were also observed in barnacles from polluted sites, indicating that oxidative stress by lipid peroxidation was not a major threat in barnacles from those sites. Seasonal differences in the GST and total oxyradical scavenging capacity (TOSC) could have contributed to the low LPO levels in the summer relative to the levels in the winter. Catalase activity and metallothionein levels were not affected by contamination or seasonality. The seasonal changes observed in biomarker responses were paralleled by the differences in temperature, which could have affected physiological responses, including the balance between pro-oxidants and antioxidants.
