Due to industrialization and environmental effects the drinking water quality has been greatly affected in Pakistan. A number of industries are draining their waste containing heavy metals without any treatment in effluents. As a result of this practice almost all of the fresh water resources are getting contaminated, although the deep aquifer in most of the countries is still safe from contami...

This study investigated simultaneous heavy metals removal and anthracene biodegradation by Rhodococcus opacus at different initial anthracene concentrations in the range 50-200 mg L-1. The heavy metals tested were Fe(III), Cu(II), Zn(II), Cd(II), Ni(II), and Pb(II) at 10 mg L-1 initial concentration: The organism was found to be well capable of removing the heavy metals along with high anthrace...

Rapid growth in urbanization and industrialization has increased the levels of heavy metals in the environment and consequently in the food chain. Consumption of contaminated food by human beings and other animals may pose a serious threat to their health. Vegetables are a major portion of the human diet, providing microand macronutrients, fibers, antioxidants, vitamins, etc. Vegetables are oft...

Other laboratories have reported biphasic effects of heavy metals on protein kinase C activity: stimulation followed by inhibition at higher concentrations. We demonstrate that these earlier findings most likely resulted from a combination of the effect of the heavy metals to liberate Ca2+ from Ca2+-EGTA buffer systems and the direct inhibitory effects of the metals on protein kinase C. Simulat...

Lead, cadmium, mercury and arsenic are the most important heavy metals which may cause health risks following consumption of contaminated foods. Table salt is one the mostly used food additive with unique place in food consumption. Although purified table salt is expected to have lower level of contamination, some Iranians still prefer to use rock salt. Use of rock salt for food purposes has be...

iron (in zero-valent and oxide forms) is used to remove numerous organic and inorganic contaminants in environment. however, there are few reports, especially in nano scale, on the remediation of heavy metals contaminated soils using zero-valent iron in the literature. in this study, the effect of iron on the availability of heavy metals was evaluated in a calcareous soil spiked with cadmium, z...

background: developmental activities especially the establishment of more than 20 industrial units in semnan province caused the officers worries about increased concentration of heavy metals in drinking water supplies and probably increasing of health risk at consumers. the aim of the study was to investigate the effect of semnan province industrial development on the health risk level caused ...
