Grain-size distribution and chemical speciation of heavy metals in chinese street dust
In order to assess the grain-size distribution and chemical speciation of heavy metals, 34 dust samples were collected in the city of Wuhu. Heavy metals concentrations in street dust of different districts varied greatly. Zn concentration in the traffic district, for example, is more than two times that of other districts, and Cu concentration in the industrial district is more than three times...
متن کاملEnvironmental Investigation and Spatial Distribution of Heavy Metals in the Street Dust of Ahvaz City
Dusts contain heavy metals such as Pb, Zn, Cu, Cr, Cd and As that can threat humanchr('39')s health and environment. Therefore, the spatial distribution of heavy metals concentration and soil pollution monitoring and environmental quality protection seem to be essential. To assess heavy metals pollution level in Ahvaz street dust, 115 street dust samples were collected from main pedestrians. Th...
متن کاملStatus, Source and Environmental Pollution Assessment of Some Heavy Metals in Street Dust of Dezful City
Heavy metals in street dust, as one of the most important environmental consequences of human activities, have attracted many researchers' attention in recent years due to their toxicity and sustainability. Therefore, this study aimed to investigate the hazard of heavy metals (lead, zinc, copper, chrome, cadmium, nickel, vanadium, arsenic and cobalt) on human health in street dust in Dezful. To...
متن کاملDistribution of metals in particle size fractions from street dust of Murcia (Spain)
Many studies on concentration of heavy metals in street dusts have been conducted. However, the distribution of metals in the different particle size fractions, which compose the dust, has been much less studied. Some authors have showed the effect of particle size in heavy metal distribution and have indicated that concentration of metals in soils increases with decreasing particle size. Fine ...
