The potentials of carbon storage by the sediments of fish ponds of Ganjam, Keonjhargarh, and Puri districts of Odisha, Krishna district of Andhra Pradesh, Moyna and Tamluk of East Medinipur, Purulia, Bankura, Murshidabad, South and North 24 Parganas districts of West Bengal, India were estimated. It is evident from the results that with an increase in fish production, the C storage decreased. The production per crop in the present study increased from 1815±376 kg/ha to 8351±1882 kg/ha and accordingly, the C storage/kg fish decreased from 1.44±0.73 to 0.62±0.21. The three types of combined humus carbon (loosely, stably and tightly combined humus carbon) were also analyzed for some sediment in the present study. The loosely combined humus varied from 36 to 43 per cent, stably combined humus varied from 4 to 6 per cent, and tightly combined humus varied from 53 to 58 per cent, respectively. Among the three combined humus, loosely combined form constitute about 40 percent of the total soil organic carbon, and thus, carbon sequestration could be 60 percent of the total soil carbon storage.","PeriodicalId":91210,"journal":{"name":"Austin journal of environmental toxicology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84065056","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}

A detailed comprehensive study of the toxicity of these materials is required in context with the prospective use in biological setting. We investigated toxicity of Graphene Oxide (GO) in rats following exposure with respect to hepatotoxicity and oxidative stress biomarkers. Four groups of five male rats were orally administered GOs, once a day for five days, with doses of 10, 20 and 40mg/Kg GO. A control group consisted of five rats. Blood and liver were collected 24h after the last treatment following standard protocols. GO's exposure increased induction of Reactive Oxygen Species (ROS), activities of liver enzymes (Alanine ALT, Aspartate AST, Alkaline Phosphates ALP), concentration of Lipid Hydro Peroxide (LHP) and morphological alterations of liver tissue in exposed groups compared to control. The highest two doses, 20 and 40mg/kg, showed statistically significant (p<0.05) increases in the induction of ROS, activities of ALT, ALP, LHP concentration, and morphological alterations of liver tissue compared to control. However, AST activity showed no effect. The results of this study demonstrate that GO may be hepatotoxic, and its toxicity might be mediated through oxidative stress.","PeriodicalId":91210,"journal":{"name":"Austin journal of environmental toxicology","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5831506/pdf/nihms925587.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35882458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
