Detail

These reports set out all relevant data, interpretation and extrapolation to proposed Environmental Quality Standards (EQS) for the following substances: mecoprop, bromine, chlorine dioxide, ethylbenzene, cypermethrin, arsenic, chromium and chromium and iron.

The development of UK-wide classification methods and environmental standards that aim to meet the requirements of the Water Framework Directive (WFD) is being sponsored by the UK Technical Advisory Group (UKTAG) for WFD on behalf of its members and partners. These technical documents have been developed through a project managed by the Environment Agency and has involved members and partners of UKTAG. It provides background information to support the ongoing development of the standards and classification methods.
