| Abstract | The 'Fish Plasma Model' has been proposed for prioritizing pharmaceuticals for in-depth environmental risk assessment efforts. The model compares estimated drug concentrations in fish plasma with human therapeutic plasma concentrations in order to assess the risk for a pharmacological interaction in the fish. In this study the equation used to estimate bioconcentration from water to fish blood plasma was field-tested by exposing rainbow trout in situ to sewage effluents from three treatment plants. Measured plasma levels of diclofenac, naproxen, ketoprofen and gemfibrozil were similar or lower than those modelled, which is acceptable for an early tier. However, measured levels of ibuprofen were >200 times higher than modelled for the largest plant (Gryaab Göteborg). Comparing measured fish plasma concentrations to the human therapeutic concentrations ranked the relative risks from the pharmaceuticals. Diclofenac and gemfibrozil, followed by ibuprofen, presented the highest risk for target interactions, whereas naproxen and ketoprofen presented little risk. Remarkably, measured bioconcentration factors varied considerably between sites. This variation could not be attributed to differences in water concentrations, temperatures, pH or exposure times, thereby suggesting that chemical characteristics of effluents and/or recipient waters strongly affected the uptake/bioconcentration of the pharmaceuticals. |

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.
