Distribution and availability of heavy metals to plants is important when assessing the environmental quality of an area. The objectives of this study conducted in 2002 were: a) determine the levels of the heavy metals cadmium (Cd), copper (Cu), lead (Pb), manganese (Mn), nickel (Ni) and zinc (Zn) in the agricultural soils of the Bursa plain so that the degree of pollution could be ascertained,...

concentrations of heavy metals were determined in muscles of kutum (rutilus frisii kutum) collected from the central part of the southern end of the caspian sea during february 2011. except for silver (ag) and nickel (ni) which were below the limits of detection, the average levels of arsenic (as), cadmium (cd), copper (co), chromium (cr), copper (cu), iron (fe), manganese (mn), lead (pb), sele...

abstract soil contamination with heavy metals is a serious problem in all over the world. soils are contaminated by many different sources of heavy metals. currently different methods are used by researchers for identifying heavy metal contamination. assessing soil metal toxicity with bacterial bioluminescence is one of the new techniques. in this study, different concentrations of zinc and cop...

soil contamination significantly reduces environmental quality and affects human health. to investigate and assess the effects of land use on the concentrations of some heavy metals in surface soils of golestan province, 227 soil samples (0-60 cm) were collected from three types of land uses including agricultural lands, natural, and industrial areas. the total metals and metalloids (cr, se, as...

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...

Current study was done to determine the concentration of heavy metals including Lead and Cadmium and nutrients element Copper and Zinc in a simple and whole wheat Macaroni in the valid different supermarkets in the city of Tehran. 254 samples from seven Iranian simple Macaroni , four foreign simple Macaroni and two Iranian whole wheat macaroni were purchased consecutively in 3 seasons of 2015. ...

this study has been carried out to determine the accumulation of heavy metals (arsenic, copper, lead, tin and zinc) in fish samples collected from former tin mining catchment. total eight types of fish family having fifteen different species are identified. cyperinidae is the most abundant family with eight different species found in the catchment. fish samples were analysed by using inductivel...
