Heavy Metal Pollution Assesment in Urban Road Network; a Case Study of Chattogram
Road surfaces generate a significant level of pollution derived from the road traffic environment influenced by the surrounding land uses. Among may different pollutants associated with road deposited sediment, selected heavy metals are commonly found in elevated concentrations and found to be varied with site-specific characteristics, and hence, it’s assessment towards human and aquatic health is deemed necessary. The present investigation was conducted at five different locations with different land uses pattern in Chattogram city to assess pollution potential of road dust at present time frame. Upon collection of road dust from selected sites, the concentrations of Cu, Cd, Pb, Ni and Cr were determined using atomic absorption spectroscopy (AAS) following strong nitric acid digestion of sediment for heavy metal extraction from solid to liquid form. To assess the pollution potentials, degree of contamination, ecological risk index, integrated pollution index, the geo-accumulation index, were computed and evaluated. Among the five study locations, named as Bahaddarhat, Patenga, Bayazid, Didar Market and Kaptai Rastar Matha, the maximum concentration of Cu, Pb, Cd, and Cr are at Patenga sampling site with 121, 164, 2, 92 mg/kg, respectively, while the maximum concentration of Ni was found as 54 mg/kg at Didar Market site. The Pb concentration was found as high as 13 times of its background concentration, indicating strong anthropogenic inputs. Among sites, Didar Market and Patenga sampling sites standing at top exhibiting the highest levels of contamination, whereas Bahaddarhat and Kaptai Rastar Matha indicating moderate pollution and Bayazid site was found with bottom standing levels. The high level of metal contamination in urban soil enriched with the pollution indices illustrates that a significant human and aquatic health hazards are associated with road dust that needs appropriate control measures.
