| Abstract | The Llobregat River, which is characterized by important fluctuations of the flow rates, receives treated waters from WWTPs. During the years 2007 and 2008, the Llobregat River basin suffered from a severe drought which affected the supply of drinking water facilities (DWF) that rely on the exploitation of the river water. The Catalan Water Agency implemented a water reuse experiment with the objective of maintaining the river flow rate at sufficiently high level so as to ensure the supply of raw water to Barcelona’s major DWF.A total of 103 emerging contaminants belonging to the groups of pharmaceuticals (74), illicit drugs (17) and oestrogens (12) were determined using LC-MS/MS methods in river water samples during the water reuse campaign. The effect of the reclaimed water discharge on the river water quality, in terms of contamination loads and environmental risk (based on the concentration addition mode), is discussed.Fifty-eight pharmaceuticals out of 74 monitored were detected at least in one sample. In river water upstream (site R0) majority of compounds were detected at low nanograms per litre levels, while downstream of discharge of tertiary effluent only few compounds were detected at levels higher than 100 ng L$^{−1}$ (i.e. acetaminophen, diclofenac, erythromycin, sulfamethazine), but never exceeding 500 ng L$^{−1}$. The total concentration of illicit drugs was found to be very low at both sampling sites (<50 ng L$^{−1}$). No relevant ecotoxicity risks were identified, except for pharmaceuticals vs. algae.In general, the discharge of reclaimed water in the river influenced perceptibly in terms of concentrations, mass loads and environmental risk, especially for pharmaceuticals and in less extent for illicit drugs. Nevertheless, it was not very significant in any case. |

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.
