“…Accordingly, we assigned a comparatively lower level value for the range of larger RDS mass per unit area because coarser particles had lower risk of metal toxicity and mobility. In addition, other factors such as metal chemical fractions could be considered in future studies to provide a better understanding of metals toxicity (McAlister et al, 2005;Kartal et al, 2006). …”

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.

“…Certified geochemical soil reference materials (CRMs) GSS-1 and GSS-2 were also analyzed to provide quality assurance and quality control (QA/QC) information. No RDS CRMs are available, but using soil CRMs has been found to be an acceptable way of determining the quality of RDS analyses in previous studies (Sutherland, 2003;Kartal et al, 2006;Zhao et al, 2010). The recoveries of the five metals that were analyzed were 75e110% (75e95% for Cr, 90e108% for Cu, 90e104% for Ni, 90e110% for Pb, and 98e107% for Zn).…”

“…Several studies have suggested that the toxicity and mobility of heavy metals depends not only on their total amounts but also on their chemical fractionation in soil (Ma and Rao, 1997;Li and Thornton, 2001;Greenway and Song, 2002;Chojnacka et al, 2005;Gupta and Sinha, 2006;Silveira et al, 2006;Kartal et al, 2006;Li et al, 2007;Tandy et al, 2009;Wang et al, 2009;Rodríguez et al, 2009). There are many classification methods to assess the chemical fractions of heavy metals in soil (Tessier et al, 1979;Ahnstrom and Parker, 1999;Qiao et al, 2003;Silveira et al, 2006).…”

A pot experiment was conducted to study the bioaccumulation and translocation of cadmium (Cd) in wheat (Triticum aestivum L.) and maize (Zea mays L.) grown in the Cd-polluted oasis soil in northwest China. The results showed that Cd in the unpolluted oasis soil was mainly bound to carbonate fraction (F2) and Fe-Mn oxide fraction (F3). However, a marked change of the Cd fractionation was observed with increasing soil Cd concentrations, where the concentrations of Cd in F1 (exchangeable fraction), F2 and F3 increased significantly (P<0.001 for F1, F2 and F3). The correlation analysis between the fraction distribution coefficient (FDC) of Cd in the soil and Cd concentration accumulated in the two crops showed that Cd in F1 fraction in the oasis soil made the greatest contribution on the accumulation of Cd in the two crops. Higher bioconcentration factors (BCF) of Cd were observed in the two crops' shoots compared with grains, and low translocation factors (TF) of Cd in the grains were observed for both crops. Cd had a higher accumulation in the edible parts of the wheat, but lower accumulation in those of the maize. Therefore, wheat grown in Cd-polluted oasis soil has a higher risk to human health, whereas maize has a lower risk suggesting that wheat is not suitable for cultivation as crop and consumption by humans in the Cd-polluted oasis soil, but that maize is suitable for plantation.
