“…RDS contaminated by metals is becoming an important threat because of the possible transmission of their pollutants to aquatic systems by urban runoff (Herngren et al, 2005;Kong et al, 2012). Excessive accumulation of metals in RDS also results in increased human exposure to metals due to their close proximity to anthropogenic activities (Christoforidis and Stamatis, 2009;Charlesworth et al, 2011). As point source pollution is reduced in China and many other countries, urban runoff with contaminated RDS has become an increasingly serious problem (Zhu et al, 2008;Zhao et al, 2010).…”

a b s t r a c tWe applied the traditional risk assessment methods originally designed for soils and river sediments to evaluation of risk associated with metals in road-deposited sediment (RDS) along an urbanerural gradient that included central urban (UCA), urban village (UVA), central suburban county (CSA), rural town (RTA), and rural village (RVA) areas in the Beijing metropolitan region. A new indicator RI RDS was developed which integrated the RDS characteristics of mobility, grain size and amount with the potential ecological risk index. The risk associated with metals in RDS in urban areas was generally higher than that in rural areas based on the assessment using traditional methods, but the risk was higher in urban and rural village areas than the areas with higher administration units based on the indicator RI RDS . These findings implied that RDS characteristics variation with the urbanerural gradient must be considered in metal risk assessment and RDS washoff pollution control.

Street dust has been sampled from eight major locations of Kathmandu city. The samples were separated into three particle size fractions (<425, 425-600 and >600 μm) and analyzed for Pb, Cu, Zn and Fe using Atomic Absorption Spectrophotometric method. Results revealed that the bulk samples as well as all particle size fractions under investigation were found to have the metal abundance order as Fe > Zn > Cu > Pb. However, the trace metal concentrations increased with the decrease of dust particle size in all samples. About 35-68% of heavy metals were associated with the small particle size fraction (<425 μm) and this particle size accounted for 64-81% of the total mass of street dust from all locations. The smaller particle size fraction has a higher heavy metal content, low density, high mobility in runoff, and thus is a higher risk for the residents of Kathmandu city. From the present study, we conclude that a monitoring plan and a suitable risk assessment are necessary to evaluate the evolution of metal concentration in dust in order to develop the proper measures for reducing the risk of inhalation and ingestion of dust for humans and environment.

“…The results of numerous studies have shown that street dust and soil samples from the urban and industrial area represents a source of compounds with potential health risk (Calvillo et al, 2015). Street dust contained significant levels of the heavy metals (Christoforidisa and Stamatis, 2009;Lu et al, 2014;Acosta et al, 2015) and lead is present in high concentration (Zhou et al, 2015). The data for Pb seem to prove that the gradual shift from leaded to unleaded petrol as fuel for automobiles has resulted in an almost proportional reduction in the concentration of Pb in dust particles under 100 μm (Zhao et al, 2015).…”

SummaryLead (Pb), which is widely used in industry, is a common element found in low concentrations in the Earth's crust. Lead has been used since prehistoric times. As a highly toxic heavy metal, the pollution and exposure risks of lead are of widespread concern for human health. This environmental contaminant causing irreversible health effects mainly in children. Especially children under the age of six are most at risk for lead poisoning. Lead toxicity causes hematological, gastrointestinal, and neurological dysfunction. Symptoms are usually noted with blood lead greater than 2 μmol/litre. Severe or prolonged exposure may also cause chronic nephropathy, hypertension, and reproductive impairment. Lead inhibits some enzymes, alters cellular calcium metabolism, stimulates synthesis of binding proteins in kidney, brain, and bone, and slows down nerve conduction. The emission sources and pathological effects of lead are discussed.
