Title: Direct toxicity assessment : a step towards better environmental protection within the UK : business strategy
Author: National Rivers Authority
Document Type: Monograph
Abstract:
This document defines the key role that Direct Toxicity Assessment (DTA) has in protecting the aquatic environment and proposes a National Strategy for the introduction of ecotoxicological procedures to help meet some business needs of the National Rivers Authority (and of Her Majesty's Inspectorate of Pollution) which are not being adequately met at present. DTA has been applied successfully in the United States for almost a decade, as part of an integrated approach to pollution control and for the protection of aquatic life. In contrast to the current procedure of exerting control through chemical specific environmental quality standards, DTA provides a direct effects response whereby a whole sample (of effluent, receiving water, sediment etc.) is taken and a single measure of toxicity obtained.
