Keywords: contamination, roadside area, heavy metals, leaded fuel, soil-plant relationship, hhpn-icp introduction highway and motorway systems in western countries are more developed than in the eastern part of europe, there- fore studies of heavy metal- especially lead- contami- nation has started earlier, in the.
Key words: bio-accessibility, lead, pollution indexes, soil contamination, urban roadside original article several studies have been carried out on roadside soils because they contain heavy metals these heavy metals have adverse environmental and health effects (23,24) neutral to slightly alkaline the average. Soil nutrient status on degradation of roadside vegetation in western australia, found that vegetation on the road verges in that area was severely affected by nutrient input from adjacent agricultural lands latif et al (2008) studied the heavy metal contamination of different water sources, soil and vegetables in rawalpindi. Pollution (10) in urban soils and road dusts, the anthropogenic sources of heavy metals are include traffic emission (vehicle exhaust a-r-t-i-c-l-ei-n-f-o aims of the study: the main objective of this study is to investigate the concentrations of cadmium (cd) and lead (pb) in the surface soils of urban parks throughout the.
From the results of this study, the ph of the roadside soils from all the sampling points ranged from 456 to 771, which enhances increased of heavy metals probably the most important natural sources of air pollution are dust storms for desert areas and volcanic activity which sometimes pour large amount of ash and toxic. The study of heavy metals in environmental niches is essential, especially with their potential toxicity to human life to identify heavy metals in roadside environment, samples of roadside soils and vegetation were collected from ten ( 10) towns along the mubi - michika the main sources of roadside contaminants are the.
850, huanghe road, shahekou district, dalian 116029, china [email protected] 163com 2 cas key this study was carried out in dawa county of the liaohe river delta, with the aim of exploring the sources of heavy metals and assessing heavy metal pollution in soils of different land use intensities. Study, performed the statistical analysis, wrote the protocol, and wrote the first draft of the manuscript the high mean value of the concentrations affirms the overall high level of the contamination of the roadside soil by this metal this observed result is in are alkaline, an indication that zn and other. Keywords: roadside soil dust heavy metals contamination enrichment factor contamination although there have been a considerable number of studies of heavy metals in roadside dust, the vast majority of in the soil that could increase the ph (jim, 1998), this could also be attributed to the alkali components in the.
Heavy metal contaminations were assessed through a detailed soil survey in roadside soils along the shenyang-dalian highway of liaoning province, china pb, cu, cd, ni, and zn were analyzed using atomic absorption spectrophotometry the average concentrations of pb, cu, cd, ni, and zn in roadside soils were. The present research was conducted to study heavy metal contamination in roadside soils of northern england roadside soil samples were collected from 35 sites in some counties of northern england and analysed for four heavy metals (cadmium, copper, lead, zinc) their concentrations and distributions in different road. In this work x-ray fluorescence(xrf) technology was used to evaluate the soil pollution with heavy metals (k, ti, cr, mn, fe, cu, zr) in rain run-off deposited metal sediment of road side soil in ado ekiti, nigeria studied area was ado ekiti city which his at 70031' n and 505' e fifty sediment sample were.
Heavy metal concentration in the roadside soil collected from the four directions was determined by x-ray fluorescence spectroscope the results indicated that the average copper concentration is higher than the soil background value of anhui province and cu was highly enriched and accumulated the order of copper. (2015) evaluation of heavy metal and total petroleum hydrocarbon contamination of roadside surface soil the present study was conducted along three major highways namely state highway (sh49), national highway (nh66 and 45a) connecting puducherry (india) for assessing heavy metals and total. 22 design of study locations along roadsides density and penetration resistance), (2) inherent fertility and presence of contamination of heavy metals, ( 3) ph, (4) texture as related to moisture imported soil and gravel substrate are often used as roadside soils after road construction, however they lack the stratified. While many workers have utilized various reagents for sequential extraction of soil trace metals, few studies have examined the order of extraction for key steps in the sequential procedure in this study, several sequences involving both adsorbed and structural (occluded) metal extractants were evaluated to determine the.
