... acute exposure to methylmercury. The toxicity of methylmercury of Nile tilapia was studied in a static renewal bioassay for 48 hours and 96 hours (96 hours L.C-50 0.22 mg/L). The study was conducted on 40 fish that weredivided into 4 groups A, B, C and D. Group A was considered as control group.Group B, C and D were exposed to sublethal concentrations of methylmercury 0.044 mg/L, 0.055 mg...

A study was conducted on total 216 fish specimens, comprised of 3 fish species (Catla catla (thaila), Labeo rohita (rohu) and Cirrhinus mrigala (mori)) from river Ravi during two flow seasons at four sampling locations including upstream Lahore Siphon = A, Shahdera = B, Sunder=C and downstream Balloki headworks = D. All the metal contents in fish scales were highly signif...

..., cadmium, nickel, lead, mercury and chromium parameters were evaluated. The experimental design was Complete Randomized Design (CRD). The data obtained was investigated at 1% probability and Least Significant Difference (LSD) test was used to segregate the significant means. The outcomes showed that percentages of EC, C:N ratio, heavy metals and organic matter decreased in vermicompost as compared to raw material while the proportion of pH, Ca, Mg, Fe, S, N, ...

Extensive histopathological variations in gills, liver, kidney and skin of different fishes were noticed when exposed to heavy metals, thus indicating severity of heavy metal toxicity. The current study was focused on the toxicological effect of Cr, Hg, Ni and Cd in different type of fishes and it would be ...

The objectives of the present study were to quantitatively estimate the residual levels of Pb, Cd, As, and Hg in camel meat and edible offal including round, liver, kidney, and tongue in samples collected from Zagazig slaughterhouse, Egypt and Al-Ahsa slaughterhouse, Saudi Arabia. Dietary intakes and potential health risks associated with the consumption of camel meat and edible of...

Hardness tests are carried out to determine surface hardness before and after the coatings. This study reveals that uniform composite coating of Ag-Sn-Cu can be achieved without Mercury using the cold spray. Hence cold spray technique can be used in the future for filling cavities and other dental app...
