Abstract | Organochlorine pesticides and polychlorinated biphenyls content can be obtained By measuring Wanzhou of the Yangtze River and Wanzhou Zhuxi River water environment (water, aquatic biota, sediment): Water and Sediment content of organochlorine pesticides and PCBs are increased flowing down; Organochlorine pesticides in the water and Sediment are β-HCH> δ-HCH> α-HCH> γ-HCH, and pp'-DDE> pp'-DDD> op'-DDT> pp'-DDT. Seasonal variation (dry and wet) the concentration of organic pollutants is obviously in water. Fish samples in Wanzhou of the Yangtze River are detected 15 kinds of POPs (HCHs, DDTs and PCBs) priority pollutants. Compared with the deposition of water and fish-like object detection results, the detection of the target substance concentration in fish is surrounded by water and sediment concentrations thousands of times. This is showed that organic matter in Wanzhou river have appeared in fish bioaccumulation effect. Through pollution assessment and risk assessment in Persistent organic pollutants, persistent organic pollutants on benthic river is very low risk of harm to human beings and biological contamination risk. Although OCPs and PCBs in water environment were very low, the impact on human health can not be ignored. Therefore certain measures were taken to clean emissions from industrial wastewater and agricultural non-point source pollution control. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
