Considering ChE, significant reduction in activity was observed following C. xanthus exposure to parathion and cadmium (48 and 96 h, respectively). Inhibition of ChE activity (IC50) related to parathion seemed to be a more consistent and sensitive effect criteria than the LC50. For GST, there was significant reduction in activity following parathion exposure (48 h). Copper did not elicit any change in ChE or GST activities in C. xanthus. The findings of this paper show the two biomarkers as promising tools for assessing exposure to contaminats in tropical regions.","PeriodicalId":163251,"journal":{"name":"Journal of The Brazilian Society of Ecotoxicology","volume":"359 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125649387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biochemical measurements were: lipid peroxidation (LPO), activity of glutathioneS-transferase (GST), alanine aminotransferase (ALT) and aspartate aminotransferase (AST). No variation of crab biochemical parameters and MC content (mean value = 32 μg kg) was verified during the depuration period. MC content of the lyophilized bloom sample was determined by HPLC (0.129 μg mg). MC concentration in water at the sampling site was 1.92 μg L. Experimental assays were also performed via oral exposure (by gavage), in doses and time exposure varying between 0 and 55 μg kg and 48 and 96 h. Analyzed variables were: GST activity (remained unaltered in all experimental conditions), LPO (augmented after 48 h in doses higher than 5.5 μg kg but the opposite was observed after 96 h at the same doses) and oxygen consumption (increased in all doses and times of exposure). We conclude that (1) there is an absent or low depuration rate of MC; (2) oxidative damage should be attenuated by antioxidant defenses other than GST; (3) higher oxygen consumption should favor reactive oxygen species generation.","PeriodicalId":163251,"journal":{"name":"Journal of The Brazilian Society of Ecotoxicology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130014160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study it was verified the feasibility of the use of the diplopod Rhinocricus padbergi as bioindicator of impacted soils by their exposition to substrates containing different concentrations of sewage sludge from different Sewage Treatment Stations (STSs). It was observed animals’ behavior and the survival rate was analyzed by log-rank test (p=0,05). The analysis showed that the animals exposed to pure sewage sludge presented higher mortality index than the specimens exposed to different concentrations of the sludge mixed with soil.

The use of certified reference materials, CRMs, is a simple and efficient way to validate analytical methods and to keep them under control. However, CRMs are expensive and usually obtained abroad, which makes their use prohibitive for a large number of Brazilian chemical laboratories. This paper presents a proposal for the preparation of a mussel reference material using the Perna perna species. This material will be used in biomonitoring studies of the Brazilian Seashore. The various aspects of the preparation such as sampling, processing, physical and chemical characterization are presented.

The differences in sensitivity were considered expressive when the ratio between 96 h-LC50s was > 2. The normalized 96 h-LC50s allowed to order the sensitivity of fish species, indicating that native species [Hemigrammus marginatus (bandeirinha) and Serrapinnus notomelas (piabinha)] are as sensitivity as traditional species [(Danio rerio (zebrafish) and Poecilia reticulata (guppy)]. Other exotic species, such as Cyprinus carpio (common carp) and Tilapia rendalli (tilapia), showed less sensitivity than other species studied.
