Bioconcentration of Pesticides in Fish from Rivers and Lakes
Pesticide contamination of river and lake waters from agriculture use is a problem of worldwide importance. Many field data on the pesticide contamination of surface waters and aquatic organisms in rivers and lakes (Amaraneri & Pillala, 2001, Abdel-Halim et al., 2006; Agradi et al., 2000; California Environmental Protection Agency, 2002; California Regional Water Quality Control Board, 2002; Ca...
متن کاملOrganotin Compounds and the Environment
Organotin compound that have at least one Sn-C bond have wide commercial applications as PVC stabilizer, antifouling agent in paint and as agrochemicals. The general formula for organotin compounds is R4SnX4 - n where R is normally alkyl or aryl groups and X=Cl-, OH-, CH3COO- . If n=3, the compound has the highest toxicity, for example Et3SnOAC has LD 50 4mg/Kg ( rats ) and this is the m...
متن کاملResidue of DDT and HCH in Fish from Lakes and Rivers in the World
Organochlorine pesticides such as DDT and HCH had been abundantly produced and used since the around twentieth century in all over the world and environmental pollution, food contamination and human body pollution had developed into social problem because of their high bioconcentration potential and high persistency. The use and manufacturing of DDT and HCH were forbidden in many countries incl...

15 صفحه اولMercury trends in fish from rivers and lakes in the United States, 1969-2005.
A national dataset on concentrations of mercury in fish, compiled mainly from state and federal monitoring programs, was used to evaluate trends in mercury (Hg) in fish from US rivers and lakes. Trends were analyzed on data aggregated by site and by state, using samples of the same fish species and tissue type, and using fish of similar lengths. Site-based trends were evaluated from 1969 to 200...
