Abstract:
The GREAT-ER (Geo-referenced Regional Exposure Assessment Tool for European Rivers) project team has developed and validated an
accurate aquatic chemical exposure prediction tool for use within environmental risk assessment schemes. The software system GREAT-ER
1.0 calculates the distribution of predicted environmental concentrations (PECs) of consumer chemicals in surface waters, for individual river
stretches as well as for entire catchments. The system uses an ARC/INFO - ArcView (ESRI) based Geographical Information System (GIS)
for data storage and visualization, combined with simple mathematical models for prediction of chemical fate. At present, the system contains
information for four catchments in Yorkshire, one catchment in Italy, and two in Germany, while other river basins are being added. GREAT-ER
1.0 has been validated by comparing simulations with the results of an extensive monitoring campaign for two 'down-the-drain' chemicals,
i.e. the detergent ingredients boron and Linear Alkylbenzene Sulphonate (LAS). GREAT-ER 1.0 is currently being expanded with models for
the terrestrial (diffuse input), air and estuarine compartments.
