Eutrophication of Natural Waters and Toxic Algal Blooms however, is the fact that almost all of the increase arrived in solution, meaning that the readily available nutrient fraction increased over the same period by almost 14-fold.

The objective was to provide a network of sites at the lower end of catchments, where water quality data could be collected and analysed in a nationally consistent manner, allowing the loads of materials carried through river catchments into estuaries to be estimated and long-term trends in river quality to be assessed. The complete list of substances to be monitored is diverse and specifies about 115 substances. The pesticides aldrin, dieldrin, -HCH, heptachlor, p,p-DDT and p,p-DDE are included.

Cyfluthrin and permethrin have agricultural approvals, but their detection in the environment is mainly associated with discharges from the moth-proofing industry. In addition, the DoE proposed EQSs in a 1991 consultation document for those pesticides on the Red List (the UK’s original priority hazardous substances list). Although non-statutory, the Government is committed to the reduction of Red List Substances discharging to the North Sea and the NRA uses the standards to assess the effects of these substances on the environment and to derive consents for point source discharges of these compounds.
