Assessment of heavy metal concentrations in the soil samples of urban parks and playgrounds is very important for the evaluation of potential risks for residents, especially children. Until recently, there has been very little data about urban parks pollution in Montenegro. To evaluate the sources of potential contamination and concentration of heavy metals, soil samples from coastal urban park...

eight selected heavy metals (cu, zn, pb, cd, cr, mn, fe and al) in surface and sub-surfacesediments in the northern coast of sfax (tunisia) were studied in order to assess the sediment quality and tohighlight the anthropogenic contributions to heavy metal distributions in the two study sediment levels.multiple chemometric approaches based on geographic information system (gis), enrichment facto...

this study at first level focused on definitions and descriptions of  some landfills and landfills sites all around the world and  survey on how important they are for regional governments and responsible in duty  as a very important responsibility for locals and their health. at the second level we had a look on heavy metals concentration which are by many definitions as follows: lead, nickel,...

The accumulation of heavy metals in agricultural soils is a serious environmental problem. The Campania region in southern Italy has higher levels of cancer risk, presumably due to the accumulation of geogenic and anthropogenic soil pollutants, some of which have been incorporated into organic matter. The aim of this study was to introduce and test an innovative, field-applicable methodology to...

Seasonal variation observations were conducted in the coastal waters of St. Martin's Island Bay Bengal to examine influence physical processes and distribution pattern nutrients ocean water. Pollution evaluation indices, health index statistical techniques incorporated assess heavy metal contamination. Two seasons, cool dry winter pre-monsoon hot, considered for sampling from 12 stations around...

Heavy metal pollution has become a serious health concern in recent years, because of industrial and agricultural development. Heavy metals of industrial bio-waste contaminate drinking water, food and air. The toxic heavy metals of great concern are Cd, Pb and Hg which are usually associated with harmful effects in men and animals. It is recognized that heavy metals may exercise a definite infl...

Heavy metals contamination in soil is one of the global issues, posing a threat not just to environment but also human health. Identifying source and distribution heavy metal pollutants around mining areas can provide scientific basis for future environmental control. Distributions (Cd, Cr, As, Ni) this study were evaluated using descriptive multivariate statistics further described geostatisti...

Over the last few decades, Anzali wetland has been at risk of pollutants, especially from heavy metals. The present research analyzes some physical and chemical properties and heavy metals concentration in 27 points in nine stations of Anzali wetland. The samples of each station have been mixed, acidic digested, and analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The mean con...

background: the most important factors and problems threatening the anzali wetland are the contaminant load and sediments entering the wetland, as well as lack of an integrated management plan for this wetland. the main objectives of the current research were to explore whether there are significant differences in concentrations of zn, cd, and pb in surface sediments among different sites (base...

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...
