background: heavy metals contaminated environment constitutes a serious problem for human and other organisms. moreover, metals such as cd, pb, and cr are toxic metals. therefore, the purpose of this study was to evaluation of cd, pb, and cr in the muscle of cow, calf, and sheep slaughtered in sanandaj city from iran. methods: this was a descriptive cross-sectional study in sanandaj city in nov...

A detailed study has been conducted to determine the contamination of Thohoyandou roadside soils, vegetation, sewage and river waters by Zn, Cu, Cr, Pb, Cd, Fe, Pt and Pd. The study further investigated the correlation between these trace metals in roadside soils and vegetation in order to infer the potential impacts of roadside trace metals contamination of vegetation. Collected surface soil a...

Tobacco (Nicotiana tabacum L.) is a commercial plant. Tobacco leaves naturally accumulate and concentrate relatively high levels of heavy metals and particular cadmium in leaves. Tobacco is one of the basic agricultural products, in Ethiopia, with social and economic importance. However, there is no report in the literature on the determination of levels of heavy metals in Ethiopian tobacco lea...

Impacts of metals to the growth and enzyme production of fungi were tested with Cd(0-10 mg kg–1), Co(0-100 mg kg–1), Cr(0-100 mg kg–1), Li(0-100 mg kg–1) or Mn(0-400 mg kg–1) containing media with ABTS [2,2’-azino-bis (3-ethylbentzthiazoline6-sulfonicacid)] as indicator of oxidative enzymes, laccase and/ or peroxidases. All ascomycetes Alternaria sp., Chaetomium sp., Epicoccum sp., Fusarium sp....

The presence of heavy metals in the environment could constitute a hazard to food security and public health. These can be accumulated in aquatic animals such as fish. Samples of four popular brands of canned fish in the Iranian market (yellowfin tuna, common Kilka, Kawakawa and longtail tuna) were analyzed for level of Cr after wet digestion with acids using graphite furnace atomic absorption ...

background: heavy metals tend to bioaccumulate in living organisms, and their accumulation has been a major concern. as mammals are known to excrete heavy metals via their bile, it seems to be very promising to analyse metal burdens of par-asites that infect the biliary tree such as liver flukes of the genus fasciola . the pre-sent study was carried out to evaluate f. hepatica and f. gigantica ...

To reveal the impact of irrigation management on the release and leaching of soil metals (Cu, Zn, Pb, Cr, and Cd), deep percolation rate and metals contents in soil solutions were observed in rice fields with nonflooding controlled irrigation (NFI) and flooding irrigation (FI) treatments. The contents of Cu and Cr in the deep solutions were safe according to the environmental quality standard f...

street dusts are suspended particle matters in the air from different natural and anthropogenic sources that may fall out because of their size and density. forty nine street dust samples were collected from some main streets of eastern and southern parts of tehran. one other sample was also collected from iran university of science and technology central campus for comparisons during summer un...

ANOVA-Analysis of variance; BISBureau of Indian standards; RTRelative toxicity; LAILeaf area index; HIHarvest index This investigation studies the enrichment and translocation of heavy metals in soil and plan of V. faba (Faba bean, var. Pusa Sumit) after fertigation with distillery effluent. A field experiment was conducted in the experimental garden of Gurukula Kangri University, Haridwar, dur...
