The heavy metals concentrations including Zinc, Copper, Lead and Cadmium (Zn, Cu, Pb and Cd) in water and sediments in Gorgan Bay and their accumulation in Rutilus frisii kutum, Acipenser persicus, Rutilus rutilus caspicus and Cyprinus carpio organs (gills, muscle, kidney and liver) were investigated. There was substantial increase in concentration of heavy m...

the increasing need for water in the arid areas of the world has resulted in the emergence of wastewater application for agriculture and landscape. using treated wastewater in agricultural irrigation can provide more adequate supply of high quality water for human consumption, but their heavy metal applications effect must be regulated to ensure no physiological problems for both the plant and ...

background: industrial development has caused the release of various pollutants including heavy metals into the environment. these toxic compounds are extremely dangerous to living beings and the environment due to their non-biodegradability, severe toxicity, carcinogenicity, the ability to be accumulated in nature and the ability to contaminate groundwater and surface water. the aim of the pre...

Fly ashes are usually contaminated with toxic heavy metals. These metals are leaching out aftercontact with water during wet disposal system, thus polluting the soil, surface and groundwater. In the present study, a hydroponics experiment was conducted to examine the removalof heavy metals Cd, Pb and Zn by Eichhornia crassipes grown at various concentration of fly ash ranging from 10, 20 and 40...

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...

aims: in the past few decades, more attention has been paid to clean up soils polluted with heavy metals by plants. a serious problem in this way is the amount of heavy metals uptake by plants. this study was conducted to evaluate the effectiveness of 3 local plants of mazandaran province, iran, in reducing and controlling the soil’s heavy metals. instrument & methods: the removal amount of thr...

during recent years there has been increasing consciousness of, and concern about, groundwater water pollution and monitoring in iran. in this context, a comprehensive review of the trace elements and heavy metals in groundwater of oshtorinan plain in northern part of boroujerd has carried out to investigate the effects of weathering minerals, agricultural and industrial activities. groundwater...
