In juvenile tilapia the effects of waterborne Cu, Cd, and combinations of these metals on whole-body Ca fluxes were studied, using 45Ca as tracer. The maintenance of Ca homeostasis in fish is crucial throughout life but is especially important in young fish; Ca is also critical for growth. Single metal exposure had no effect on Ca fluxes after 6 d of exposure. In fish coexposed to 200 p.g Cu L“...

  The Kor River (Fars province) was divided into three parts and water and fish specimens were collected monthly and the concentrations of four heavy metals were determined using the Induction Coupled Plasma Method. As middle sampling zone was the main entrance and discharges of industries into the River, the concentrations of heavy metals in tissue of fish from this zone were significantly hig...

determination of metal levels in muscle, liver and gill of common carp ( cyprinus carpio ) species caught from shirinsu wetland was done using icp-oes. the mean level of cu, pb and zn in muscle, liver and gill of fish were 0.01±0.002, 0.015±0.003, 0.007±0.001; 0.13±0.005, 0.006±0.001, 0.62±0.11 and 0.26±0.008, 0.009±0.002, 0.53±0.10 μg g −1 , respectively. metal levels in muscle were generally ...

Aim: Three species of fish, Notoptrus notoptrus, Channa punctatus and Glossogobius giuris, were shown to accumulate heavy metals like Zn,Fe,Ni,Pb,Cd, Cu in their gut-free bodies, liver, gills. Methodology: These fish inhabit the Kapila River Nanjangud area Mysore district. Result: Fish tissues (muscle, gills liver) sediments found contain Fe, Pb, Ni, Zn pollution. It was also determined that th...

aim: this study was conducted to investigate the accumulation of three heavy metals including lead, tin and zinc in the liver and muscle tissues of 60 silver carp (hypophthalmichthys molitrix) collected from different stations of the anzali wetland (located at the west south of caspian sea): pirbazar, anzali, khazarvila, beshman, sangachin and abkenar, in april 2011. materials and methods: samp...

this study has been carried out to determine the accumulation of heavy metals (arsenic, copper, lead, tin and zinc) in fish samples collected from former tin mining catchment. total eight types of fish family having fifteen different species are identified. cyperinidae is the most abundant family with eight different species found in the catchment. fish samples were analysed by using inductive...

In-situ caged rainbow trout (Oncorhynchus mykiss) studies reveal significant fish toxicity and fish stress in a river impacted by headwater acid rock drainage (ARD). Stocked trout survival and aqueous water chemistry were monitored for 10 days at 3 study sites in the Snake River watershed, Colorado, U.S.A. Trout mortality was positively correlated with concentrations of metals calculated to be ...

Many industrial and agricultural chemicals (including heavy metals and alkylphenols) present in the environment have adverse effects on the reproductive function in fish. Three studies were conducted to assess toxicity of these chemicals towards reproduction of freshwater fish. It was shown that heavy metals added to the diets accumulate in brain tissue of carp, and this accumulation results in...
