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 ...

 The concentrations of Cd, Pb, Ni and Hg were determined in gill, liver and muscle of Barbus xanthopterus in down streams of Karoon and Dez Rivers during summer 2009. Heavy metal concentrations varied significantly, depending on the types of the tissue in fish species. The levels of heavy metals such as Cd, Pb, Ni and Hg in the Barbus xanthopterus of Karoon River were higher than in Barbus xant...

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...

Introduction: Hydrochemical properties of waters used in balneotherapy are very important, as they play a key role in success or failure of this kind of treatment. There are 30 mineral and hot spas in Hormozgan Province, Southern Iran, which are traditionally used for treating diseases. In this study, hydrochemical properties of Fotoyeh and Sanguyeh Springs, in western Hormozgan Province, are d...

the contamination of riverbed sediments by heavy metals has assumedserious problems due to their toxicity and accumulative behavior. the present studyinvestigated the concentrations of heavy metals from the bottom sediments of shitalakhyariver to understand the level of contamination and their distribution. the averageconcentrations of heavy metals al, k, ca, mg, fe, as, cu, co, cr, and zn are ...

heavy metal contamination has been and continues to be a worldwide phenomenon that heavy metals in the soil have an effect on environment and food quality, and may threaten human health. no information is currently available on the distribution pattern of heavy metals concentration in soils of golestan province. the objective of this research was to determine the spatial distribution of cd, as,...

background: soil pollution and accumulation of heavy metals in crops in industrial areas is one of the most important environmental issues threatening the life of plants, animals, and humans. the aim of this study was to determine the concentration of cr and cd in the soil and barberry plants in farms surrounding the qayen cement company, south khorasan province, iran. materials and methods: in...
