Concentrations of heavy metals (Cd, Ni and Pb) were determined in soft and hard tissues (three separated shell sections) of gastropod Bufonaria echinata as well as surficial sediments collected in October 2015 from two sampling sites located in the sub-littoral zone of Qeshm Island, Persian Gulf. There were significant differences between the sampling sites for concentrations of all the three e...

conclusions pine trees can be used as a worthy bio-indicator for hms pollution monitoring in the ambient air in areas with extensive vegetation of pine trees. results iron had the highest concentration (345.0053 mg/kg) in leaves when compared with other hms. the concentration of zn, cu, pb and cd were 26.1384, 5.5905, 2.9963 and 0.7383 mg/kg, respectively. spatial mapping indicated that industr...

background: soil and sediment serve as major reservoir for contaminants as they possess ability to bind various chemicals together. in this study the concentrations of heavy metals cd, cr and cu were analyzed in surface sediments of agh gel wetland in west of iran. methods: the sediment samples were taken from 10 stations. the samples were subjected to bulk digestion and chemical partitioning a...

Water pollution by anthropogenic activities is proving to be of critical concern as the heavy metals affect aquatic organisms and can quickly disperse to large distances. This poses a risk to both human health and the aquatic biota. Hence, there is a need to treat the wastewater containing toxic metals before they are discharged into the water bodies. During recent years, magnetic nanoparticles...

the physico-chemical parameters, nutrient status and heavy metal ions of huluka and alaltu rivers of ambo, ethiopia were studied. temperature, ph, electrical conductivity, co2 content, total dissolved solids, hardness, dissolved oxygen, ca2+, mg2+, cl-, nitrate, phosphate and sulphate have been determined along with selected heavy metals to assess the various water quality profiles along the ri...
