Mugil cephalus; bioaccumulation; biochemical oxygen demand; biomarkers; brackish water; chemical oxygen demand; dissolved oxygen; enzyme activity; estuaries; fish; heavy metals; hepatocytes; hydrochemistry; oxidation; oxidative stress; pollutants; salinity; temperature; wastewater; India
Abstract:
... The aim of the study was to evaluate the impact of environmental contaminants on oxidative stress biomarkers in hepatocytes of Indian estuarine water grey mullet, Mugil cephalus collected from unpolluted Kovalam and polluted Ennore estuaries. Initially, a comparison was made between the general water chemistry and environmental pollutants like heavy metals to identify the ecotype of the estuaries. ...

Abstract:
... Old Fort Lake, a small (1.6 ha), shallow, and recreational water body in Delhi (India) was studied through monthly surveys in two consecutive years (January, 2000-December, 2001). Precipitation is the major source of water for this closed basin lake. In addition, ground water is used for replenishing the lake regularly. This alkaline, hyposaline hard water lake contains very high ionic concentrati ...

Abstract:
... The seasonal effects of untreated and treated municipal sewage on the nutrients--nitrate (NO₃), phosphate (PO₄), sulphate (SO₄), and the biochemical oxygen demand (BOD), chemical oxygen demand (COD) and dissolved oxygen (DO) of the receiving urban canal, the Buckingham canal at Kalpakkam (Tamil Nadu, India) was monitored monthly during pre- monsoon--2005 to post-monsoon--2006. The NO₃, PO₄ and SO₄ ...

Abstract:
... The study illustrates the utility of STREAM II as a modeling package to determine the pollution load due to organic matter in the River Yamuna during its course through the National Capital Territory that is Delhi, India. The study was done for a period from 1995-2005. Model simulates the dissolved oxygen and biochemical oxygen demand parameters in a two-dimensional fashion by performing the numer ...
