EDCAT - Endocrine Disruption in Catchments
EDCAT 3/4: Exposure Measurement
This research will provide important analytical chemistry inputs to EDCAT 2 (both in terms of oestrogenic and non-oestrogenic substances) and will assess the distribution of oestrogenic, androgenic, and anti-androgenic activity. The aim is to improve understanding of the fate, behaviour, distribution and exposure to endocrine disrupting substances; to map the spatial and temporal influences using key sewage markers/endocrine disrupters and oestrogenic, androgenic and anti-androgenic activity (as measured by in vitro screening assays) within the catchment. Changes in general water quality in terms of dissolved oxygen, pH, temperature and conductivity will also be measured and assessed throughout the project. Representative non-endocrine pollutants and activities will also be investigated.
Results will identify potential hot-spots and will afford before/after measures of management action (through EDCAT Phase 2) to provide information on dissipation of pollutants and recovery following remedial action. Results will integrate tightly with EDCAT 2 and 5.
