Abstract:
Two river water samples taken from the Red River at Gwithian Towans during June 1990 had total mercury concentrations of 3.9 microg/l and 6.6 microg/l. These exceeded the EQS for total mercury for inland surface water quality of 1.0 microg/l although as the EQS is based on an annual mean overall compliance with the EQS during 1990 was achieved at this site. Mercury data from this site are used in reporting for the EC Dangerous Substances Directive, Harmonised Monitoring, Red List and Paris Commission programmes. The Department of the Environment is committed to the reduction of substances described as Red List Substances, by approximately 50%, by 1995. An investigation was undertaken to provide information on the source of the high levels of mercury.
