| Abstract | Polycyclic aromatic hydrocarbons (PAHs) in sediments of the Subei Grand Canal (SGC) are thought to have a significant effect on the water quality of the South to North Water Transfer Project in China. The SGC is in Jiangsu Province and is the northern section of the Beijing-Hangzhou Grand Canal; it is also part of the eastern route of the South to North Water Transfer Project. In the present study, 37 surface sediment samples were collected from the SGC and were analyzed by high performance liquid chromatography (HPLC) for their PAH concentration. The total PAH concentration in surface sediments was moderate, and ranged from 634 to 14,703 ng/g (dry weight), with a mean of 5239 ng/g. There was significant spatial variation in the total PAH concentrations; for example, the mean concentrations in the Xuzhou area, Huaian-Suqian area, and Yangzhou area were 9708, 3872 and 2376 ng/g, respectively. The organic carbon content (9.4–99.6 mg/g) had an important influence on the PAH concentrations in sediment. Analysis using PAH ratios and PCA indicated that the main sources were coal and wood combustion, vehicular and shipping emissions, and coke ovens. An ecological risk assessment based on biological threshold showed that the PAH in surface sediments of the SGC had the potential to cause adverse biological effects to aquatic organisms, and that these effects were more serious around Xuzhou than in the other areas. |

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.
