The objective of this study has been to specify an information system which, if effectively managed, would satisfy the requirements for ecotoxicology information within the NRA. Establishing such a system is a multistage process that entails: (i) an assessment of the need for information; (ii) proposals for specific solutions to satisfy this need; (iii) an investigation into the feasibility of these solutions; (iv) a detailed specification of the information system; and (v) an implementation plan. The objective of this study was to consider stages (i) to (iii). The remaining stages will require the involvement of information technologists within NRA, since more detailed discussions and studies are required before a system can be selected, specified and implemented. In addition to the specification of an information system, a number of pieces of supporting work have been produced with direct relevance to the type of system (e.g. internal or external), its information sources, and data requirements for the derivation of water quality objectives (e.g. EQSs, Likely Safe Environmental Concentrations).
