These proceedings present information on regulatory controls and impact assessments of toxic waste entering the aquatic environment. Topics covered include: current legislation in the United Kingdom and Europe; toxic measures of environmental damage; and assessment of toxicity.

These proceedings present information on regulatory controls and impact assessments of toxic waste entering the aquatic environment. Topics covered include: current legislation in the United Kingdom and Europe; toxic measures of environmental damage; methods to improve and provide more rapid assessment of toxicity; and the application of quality control procedures to ensure good information from test procedures. A number of case studies were examined, demonstrating environmental damage arising from toxic inputs and others on toxicity identification and reduction evaluation programmes. Additionally, political and economic implications were considered with a view to the further development of methods and procedures to help improve and protect aquatic life.
