| Abstract | The investigation of the Yunnan tin mining surrounding (smelter around, mining under, mining) farmland soil and the analysis of the heavy metal pollution of six kinds of leafy vegetables. Meanwhile we have evaluated the potential ecological risks of soil metal pollution and the edible parts of leafy vegetables. The results show that: 1)Yunnan tin mining circumjacent study regional soil was heavy metal pollution. Through pollution degree grade: the farmland of smelter around > the farmland of mining under > the farmland of mining. 2) There is a great variation of six kinds of leafy vegetables that collected from different location. Heavy metal pollution soil makes the leafy vegetables heavy pollution. Lead and cadmium pollution particularly serious, chromium, copper and zinc less polluted. 3) the six kinds of leafy vegetables edible parts: Cd displays for strong ecological risks, Pb performance for medium to strong ecological risks, Cr, Cu and Zn performance for slight ecological risks. From a variety of heavy metal potential ecological harm index RI see, six species of leafy vegetables potential ecological risk index RI were greater than 600, regional six kinds of leafy vegetables potential ecological risk harm is very strong. |

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.
