... contamination caused by heavy metals (Cd, Cr and Ni). Soil samples were collected from both orchard and non-orchard fields and were extracted with Aqua-regia and Mehlich-3 extracting solutions for total and available metals respectively. Wheat crops from both fields (orchard and non-orchard) were collected and analyzed with aqua-regia for heavy metals contents. Results showed that the average concentrations of metals in soi...

The concentration of heavy metals (Pb, Cd, Cr, Fe, Mn and Zn) present in poultry egg and meat were determined in the following three districts; Peshawar, Dir Lower and Malakand of Khyber Pakhtunkhwa by using atomic absorption spectrophotometer. In all the three districts the egg albumen was found to contain significantly higher levels of Pb, C...

GSH: GSSG ratio declined after As, Pb and Cr treatment, whereas non-protein thiol levels were higher after Cd and As treatment followed by those of Pb, Cr and Cu treatment. Candida sp. PS33 was able to remove 78% (Cd), 70% (As), 82% (Cu), 65% (Cr) and 87% (Pb) from the medium ...

The level of Pb was found to exceed the maximum permissible limit (0.02 µg/g) set by Codex Alimentarius Commission in 53% milk samples. In 44% milk samples the level of Cd was found to exceed the permissible limit (0.0026 µg/g) set by International Dairy Federation (1979). The mean levels of Ni, Cu and Co were found in the normal ranges. The data for e...

Biofilm formation is one such resistance mechanism for bacterial survival. This paper provides the basis for use of bacteria isolated from saline environment and to check their biofilm forming ability under nickel stress. Our previous results showed that these bacteria are capable of producing proline, g...
