background: a pot experiment was conducted to determine the toxic effects of some heavy metals on the plant growth and seed yield of maize (zea mays l.). materials and metheds: heavy metals mn, pb, cd, cr and co individually and in combinations were added as chloride salts in solutions to the pots before sowing. the test plants for were harvested after 80 days of germination and evaluated for n...

background: the presence of heavy metals in dialysis water which enters patients’ body through haemodialysis can cause various problems such as acute poisoning, brain damage, osteoarthritis etc. therefore, applying the standards for dialysis water is indispensable. this study was carried out to determine the heavy metals of the enterence water of dialysis machines and its comparison with aami a...

background: the aim of this study was to determine bioavailability heavy metal concentrations of cu, cd, cr, co and zn and health risk assessment in different types of klang district, selangor (malaysia) urban surface soil using in physiologically based extraction test in vitro human digestion model. methods: a total of 76 urban surface soil was sampled based on seven different types of land us...

metal pollution has become one of the most serious environmental problems resulting from human activity. phytoremediation utilizes plants to uptake contaminants and can potentially be used to remediate metal-contaminated sites. the present study investigates heavy metal uptake (cd, cr, and ni) from soil by different organs of populus alba and morus alba. for this purpose, cd (40, 80, and 160 mg...

plant-based remediation (i.e. phytoremediation) is one of the most significant eco-sustainable techniques to cope with devastating consequences of pollutants. in the present study, the potential of a wetland macrophyt (i.e. potamogeton crispus ) for the phytoremediation of heavy metals (i.e. cu, cr, pb, as and cd) in the anzali wetland was evaluated. the results showed that p. crispus tends to ...

background: given the importance of vegetables in the food pyramid, their safety is very important from view point of public health. vegetable contamination by heavy metals can lead to bioaccumulation of these toxic and disease-causing elements in the body of consumers. therefore, in this study, the concentration of some heavy metals, including lead (pb), cadmium (cd), zinc (zn) and copper (cu)...

background and aims: nowadays heavy metals are the environmental priority pollutants and are becoming as the most serious environmental problems. in recent years removing those from diverse industrial effluents and metal cleaning have been studied. the aim of the present study was to investigate the different methods for cooper removal of cooper ions from industrial wastewater. methods: this st...

SUMMARY: The disposal of fly ashes from municipal solid waste incineration (MSWI) is becoming a growing environmental issue in Europe. In order to avoid landfilling and recycle MSWI fly ashes, initiatives aim to recycle them in cement production. While numerous studies have analyzed the impact of MSWI ashes application on the concrete quality and the leaching of potentially hazardous heavy meta...

Several electroplating industry including agricultural sector industries, sewage treatment and mining operations all combine to generate hazardous waste water containing enormous amounts of toxic heavy metals. The accumulation of toxic heavy metals in human beings and animals cause many metabolic disorders. Heavy metal concentration was estimated in sewage, sludge and electroplating wastewater ...

Introduction: Heavy metal pollution is one of the most serious environmental issues globally.In this research we were studied the heavy metal concentrations in sediment and fish in Persian gulf. Materials & Methods For determination of heavy metal concentrations in sediments 8 sampling stations were selected to measure Cd, Zn, Ni, Pb and Fe in the sediments and in the muscle tiss...
