“…From this assertion, the input of Cd and Pb to the environmental soil should be given a thorough check since the metals are very mobile in soil. Contaminated soils may constitute very serious health hazards if the metals are transferred to other reservoirs such as underground water, aquatic habitats, plants and the entire ecosystem (Stones and Marsalek 1996;Turer and Maynard 2003).…”

The optimized BCR sequential extraction procedure was applied to nine roadside soil samples for the determination of Cd, Cr, Pb and Ni. The extractable metals were isolated into three operationally defined fractions viz: acid extractable, reducible and oxidizable. The residue was treated with aqua regia solution. Metal analysis was done using flame atomic absorption spectrophotometry with airacetylene flame. Results obtained showed the concentrations of the metals as relative abundance in the mobile phases of the samples (based on the sum of the first three fractions) are in the following order: Cd(91.9) [ Pb(82.8) [ Ni(49.5) [ Cr(39.0). The most non-mobilizable metals were Cr and Ni which are generally lithogenic, associated with the silicate matrix, and the order is as follows: Cr(61.0) [ Ni(50.5) [ Pb(17.2) [ Cd(8.1). The recovery of all the metals expressed as the ratio of total metal concentration to fractional sum of the optimized BCR sequential extraction procedure was of the order: Cr(95.6) [ Pb(95.0) [ Ni(94.8) [ Cd(92.4).

“…In the last decades, much attention has been directed towards lead in the roadside environments as a result of its widespread use as an anti-knocking agent in gasoline (DAVIES & HOLMES 1972;WHEELER & ROLFE 1979;HAFEN & BRINKMANN 1996;TURER & MAYNARD 2003). In the recent years, however, the lead content in gasoline was markedly decreased in the UK after the introduction of the regulations requiring the reduction in the lead content from 0.64 g/l in 1966 to 0.14 g/l in 1986.…”

“…The heavy metals can impair important biochemical processes posing a threat to human health, plant growth and animal life (JARUP 2003;MICHALKE 2003;SILVA et al 2005). Studies have shown that such pollutants can be harmful to the roadside vegetation, wildlife, and the neighbouring human settlements (MUSKETT & JONES 1980;KHAN & FRANKLAND 1983;NDIOKWERE 1984;IQBAL et al 1994;FERRETTI et al 1995;CASELLES 1998;TURER & MAYNARD 2003). The distribution of these metals in the roadside soils is strongly but inversely correlated with the increase in the distance from road (WARREN & BIRCH 1987; BHA-TIA & ChOUDHRI 1991;AKSOY 1996).…”

The pollution of soils by heavy metals from automobile sources is a serious environmental issue. These metals are released during different operations of the road transport such as combustion, component wear, fluid leakage and corrosion of metals. Lead, cadmium, copper, and zinc are the major metal pollutants of the roadside environments and are released from fuel burning, wear out of tyres, leakage of oils, and corrosion of batteries and metallic parts such as radiators etc. (DOLAN et al. 2006).The majority of the heavy metals are toxic to the living organisms and even those considered as essential can be toxic if present in excess. The heavy metals can impair important biochemical processes posing a threat to human health, plant growth and animal life (JARUP 2003;MICHALKE 2003;SILVA et al. 2005). Studies have shown that such pollutants can be harmful to the roadside vegetation, wildlife, and the neighbouring human settlements (MUSKETT & JONES 1980;KHAN & FRANKLAND 1983;NDIOKWERE 1984;IQBAL et al. 1994;FERRETTI et al. 1995;CASELLES 1998;TURER & MAYNARD 2003). The distribution of these metals in the roadside soils is strongly but inversely correlated with the increase in the distance from road (WARREN & BIRCH 1987; BHA-TIA & ChOUDHRI 1991;AKSOY 1996). This study constitutes a part of a broader research project on the ecology and conservation of the roadside Abstract: Environmental pollution of heavy metals from automobiles has attained much attention in the recent past. 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 verge zones (border, verge, slope, ditch) were determined. Lead concentration was the highest in the soil and ranged from 25.0 to 1198.0 µg/g (mean, 232.7 µg/g). Zinc concentration ranged from 56.7 to 480.0 µg/g (mean, 174.6 µg/g) and copper concentration ranged from 15.5 to 240.0 µg/g (mean, 87.3 µg/g). Cadmium concentration was the lowest in the soil and varied from 0.3 to 3.8 µg/g (mean, 1.4 µg/g). Though the levels of heavy metals in roadside soils were higher as compared to their natural background levels in British soils, their concentrations in general, however, were below the 'critical trigger concentrations' for the contaminated soils. All the four heavy metals exhibited a significant decrease in the roadside soils with the increasing distance from the road. The border zone had the highest mean concentration of the four metals whereas the ditch zone exhibited the lowest mean concentration.

“…The road transports mainly contribute in polluting nearer soils by pollutant transfer through the atmospheric fallouts [60][61] or road runoff [60][61][62]. Most of the researchers mentioned that the impact of the traffic load on heavy metal contents in top soils and their inconsistency with distance [63][64][65][66][67][68]. The highest concentrations for lead was recorded in soil (0.1931 ppm) and in plants (0.1358 ppm) for highway on road at 0m distance.…”

Abstract:Heavy metal, one of the most hazardous pollutant that can pose serious threat to human and environment. The concentrations of metals are increasing at an alarming rate due to boost of unplanned industrialization and urbanization. Though some metals are playing crucial role as micronutrients but the excessive amount exert negative impact at great extent. The existence of toxic heavy metals in the air, water and sediment can cause severe problems to all organisms because of their long persistence nature and bioaccumulation in the food chain. The present study reviews the various area of Bangladesh to make information on the sources of metal pollution, dissemination of metals in the environment and their possible effects on atmosphere, water, sediment, fishes and vegetables (plants).
