| Abstract | Contaminated sites will restrict regional development, especially the residential area development as the contamination can pose long-term adverse health risks. Western Suzhou, where three mining areas are located, is a rapid urbanization area in Suzhou City, Jiangsu Province, the People’s Republic of China. This urbanization has been pushing into the mining areas. This study aims to assess the heavy metal contamination (including Cu, Zn, Pb, Cd, Hg, Cr, As, and Ni) and identifies the contaminated sites in Western Suzhou.Fifty soil samples and 34 road dust samples in Western Suzhou including a closed mine (A1), a mineral concentration plant (A2), and a newly opened mine (A3) were collected and analyzed. The geo-accumulation (I $_{geo}$) methodology, principal component analysis (PCA), spatial interpolation, and health risk assessment were employed for evaluation.The contamination levels are ranked in the orders of Cd > Pb > Zn > Cu > As > Hg > Ni > Cr for soils and Cd > Pb > Zn > Cu > As > Ni > Hg > Cr for road dusts. The concentrations of heavy metals in the road dusts are generally higher than those in soils. Copper, Zn, Pb, Cd, and As are the main contaminants and mainly due to mining activities. Lead, Cd, and As in the soils and road dusts in the three mining areas pose high non-carcinogenic risk to children. Spatial analysis shows that the soils and road dusts in areas A1 and A2 have the highest concentrations of heavy metals, followed by area A3, where only the road dust exhibits high concentrations.The results show that there exist contaminated sites in areas A1 and A2 and remediation measures are urgently needed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
