| Abstract | One of the aims of the Water Framework Directive is to derive Europe-wide environmental quality standards that are scientifically based and protective of surface waters. Accounting for water type-specific bioavailability corrections presents challenges and opportunities for metals research. In this study, we present generally applicable approaches for tiered risk assessment of chemicals for prospective use. The objective of the present study was to derive water type-specific dissolved copper criteria for Dutch surface waters. The intent was to show the utility of accounting for bioavailability by using biotic ligand models (BLMs) and two different ways of extrapolating these BLMs in order to obtain reliable bioavailability-corrected species sensitivity distributions. Water type-specific criteria estimations were generated for six different water quality conditions. Average hazard concentrations as calculated using the BLMs and the two alternate normalization scenarios varied significantly among the different water types, from 5.6 to 73.6 microg/L. Water types defined as large rivers, sandy springs, and acid ponds were most sensitive for Cu. Streams and brooks had the highest hazard concentrations. The two different options examined for toxicity data normalization did impact the calculated hazard concentrations for each water type. |

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.
