Background and purpose: There is an increasing interest towards consumption of aquatic products, therefore, the health of aqua ecosystems is highly important. Heavy metal pollution in fish is a global concern due to its bioaccumulation potential, toxicity and persistence in food chain. This study investigated the concentration of heavy metals (cadmium, lead, chromium, copper, and zinc) in the g...

The accumulation of iron, zinc, copper and cobalt in the muscles of three freshwater fish (Cyprinus carpio, Squalius cephalus and Capoeta umbla) from Keban Dam Lake (Turkey) were investigated between September 2009 and April 2010. The concentration of heavy metals were found as Zn>Fe>Cu>Cd respectively. A positive relationship was found between heavy metal levels and fish size. The levels of al...

Anthropogenic pollution with heavy metals is an on-going concern throughout the world, and methods to monitor release and impact of heavy metals are of high importance. With a view to probe its suitability as molecular biomarker of metal pollution, this study has determined a coding sequence for metallothionein of the African sharptooth catfish Clarias gariepinus. The gene product was recombina...

Heavy metals are considered as the most important pollutants of the aquatic environment. In the present study, acute toxicity test was used for the determination of lethal toxicity of Nickel in adult fish, Channa gachua as the test organism. Toxicity test is most reliable for accessing the adverse effect of pollutants on aquatic life. The LC50 values were determined and observed that the values...
