the  present study was aimed  at comparing the ability of three crop plants for phytoremediation of zinc (zn) and nickel (zn) from soils. a factorial (3×2×3) experiment based on rcbd was  used to compare the treatments,  and was repeated three times. the first factor was crop type (wheat, clover and rapeseed), the second factor was heavy metal types (zinc (zn) and nickel (ni)) and the third fac...

bioaccumulation of heavy metals in the skulls of black-striped field mice (apodemusagrarius) was compared for two localities in serbia differing in the level of pollution. eight heavy metals: fe, mn, co, cd, zn, ni, pb and cu, were quantitatively analyzed by atomic absorption spectrophotometry.four of them (mn, cd, fe and ni) showed significantly higher concentrations at the polluted location t...

The heavy metal is not easily degradable, the heavy metal pollution of water is the most harmful pollution for the environment, so, to evaluate the pollution grade is very important for pollution controlling. The fuzzy evaluation method is the most important way to evaluate the degree of pollution today. But in some case, one key factor of heavy metal will decide the pollution level, but the cl...

background: due to the increasing pollution of water resources, this study was carried out for evaluation of water quality pollution indices for monitoring of heavy metals (as, zn, pb and cu) contamination in ghahavand plain, hamadan province, western iran during spring and summer 2012. methods: totally, 20 ground water wells were chosen randomly. the samples were filtered (0.45 μm) and maintai...

background: iran is located within the dry and semi dry regions, thus almost 90% of the required water is secured via the use of groundwater. owing to the increasing pollution of water resources, this study was performed to evaluate water quality pollution indices for heavy metals (as, zn, pb and cu) contamination monitoring in toyserkan plain during spring and summer in 2012. methods: a total ...

Heavy metal pollution in farmlands is a serious threat to sustainable agricultural development and has become a major agro-ecological problem that has attracted public concern in China. This study proposes a soil–crop collaborative risk assessment model that aims to assess the potential safety risks of heavy metal pollution in farmland soils by considering the concentrations of heavy metals in ...

present survey studies intensity of heavy metals pollution (ca, fe, ni, cd, pb, zn, as, hg) in the sediments of bamdezh wetland. the main objective of the study is to quantify heavy metal pollution intensity in the wetland. other objectives of the study are separation of natural and anthropogenic heavy metal pollution and identification of the origin of heavy metals. results of this study shows...

soil can register environmental pollution in itself, so the pollution of an area can be studied through the chemical analysis of its soil. in the present study, the soil ofmellatparkintehranwas sampled. in total, 15 soil samples were collected. using laboratory methods, the mean concentration of pb, zn, and ni were obtained to be 145, 33, and 62 mg/kg, respectively. the results show that the co...

this research was done in hydroponic environment in greenhouse at 3 stages (vegetative, flowering and full product) in 5 concentrations of cd (0.1, 0.3, 0.9, 2.7, and 10 mm) for investigating physiological and biological effects. this study revealed that the increase of cd concentration in understudy treatments causes the 49% reduction of sugar solution in 10 mm treatment. on the other hand, th...
