“…However, in this study, a short-term exposure to sanitary sewage did not change the activity of these enzymes in both tissues analyzed. Similar results were observed in oysters Crassostrea brasiliana exposed for 36 h to PAHs (Lüchmann et al 2011). Zanette et al (2008 observed higher CAT activity in gills and digestive gland of oysters Crassostrea rhizophorae after 14 days of in situ exposure to a sanitary sewage contaminated site, but the same was not observed in C. gigas exposed simultaneously at the same location.…”

Urban effluents are rich in nutrients, organic matter, pharmaceuticals and personal care products (PPCPs), pesticides, hydrocarbons, surfactants, and others. Previous studies have shown that oysters Crassostrea gigas accumulate significant levels of linear alkylbenzenes (LABs) in sanitary sewage contaminated sites, but there is little information about its toxicological effects in marine bivalves. The aim of this study was to analyze the transcription of genes in two tissues of C. gigas exposed for 12, 24, and 36 h to LABs or sanitary sewage. Likewise, the activity of antioxidant and biotransformation enzymes was measured in oysters exposed for 36 h in all groups. Oysters exposed to LABs and oysters exposed to sanitary sewage showed different patterns of transcriptional responses. LAB-exposed oysters showed lower level of biological responses than the oysters exposed to sanitary sewage. Despite the ability of the oyster C. gigas to accumulate LABs (28-fold), the data indicate that these contaminants are not the cause for the transcriptional responses observed in oysters exposed to sanitary sewage. Possibly, the biological changes observed in the sanitary sewage-exposed oysters are associated with the presence of other contaminants, which might have caused synergistic, additive, or antagonistic effects. The results show that FABP-like and GST-ω-like messenger RNAs (mRNAs) have a rapid response in tissues of oyster C. gigas exposed to sanitary sewage, suggesting a possible protective response and a role in maintaining homeostasis of these organisms.

“…As such, they are important sentinels of chemical stress. Luchmann et al (2011) reported that Hsp60 was upregulated and Hsp90 was repressed in the gills and digestive gland of Crassostrea brasiliana oysters after exposure to diesel fuel, with Hsp60 being the most prominent biomarker in gills. Similarly, Hsp90 was down regulated in Tanichthys albonubes by exposure to cadmium (Liu et al, 2012).…”

“…Previous studies have reported that various stressors (e.g., temperature, metal toxicity and infection) affect the expression of Hsp60, Hsp70, and Hsp90 transcript and protein levels (Luchmann et al, 2011;Liu et al, 2012;Zhang and Zhang, 2012;Jing et al, 2013). Likewise, Kim et al (2011) reported that low doses of UV-B radiation (2 and 4 kJ/m 2 ) increased the expression of Hsp10, Hsp20, and Hsp27 mRNAs in Brachionus rotifers.…”

“…In this study, an increasing trend of SOD and CAT activities were observed in the tissues of zebrafish exposed to MAL, ATR and Cd, and a more pronounced increase was found in muscle with increased toxin concentration, especially at high concentration for all toxicants. It was supposed that the increase in SOD activity was primarily due to higher O 2 -production [37]. As the first defense mechanism against oxidative stress, antioxidant defense works to protect living organism from free radicals produced by oxidation and other stress, thus having great significance for fish [11].…”

Abstract-The acute toxicity of melathion (MAL), atrzine (ATR) and Cadmium (Cd) in zebrafish (Danio rerio) were investigated by acute toxicity (LC 50 ), and the results showed that the 96 h LC 50 followed the order: MAL>Cd>ATR. Furthermore, the accumulation of ecotoxicity in zebrafish body and correlated biochemical responses in brain and muscles were explored and it was found that MAL, ATR and Cd could be rapidly accumulated in fish body shortly after exposure. The activities of superoxide dismutase and catalase in fish body increased after 96h exposure. The acute toxicity caused protein reduction in brain and muscles, and elevation of total lipid dry weight in fish body. Besides, some dose-dependent inhibition of AChE activity was found in brain and muscles of zebrafish exposed to higher concentrations of acute toxins. These can be employed in biomonitoring programs because they showed good correlation with toxins and were sensitive to different concentration patterns.
