19、 This International Standard consists of two parts. Part 1 describes a die-away batch test for either surface water with or without added sediment in suspension simulating either a pelagic aquatic environment or a water-to-sediment interface. Part 2 describes a continuous flow system simulating a ri
20、ver with biomass attached to stationary surfaces. The test has been specifically designed to provide information on the biodegradation behaviour and kinetics for test compounds at low concentrations, i.e. sufficiently low to simulate the biodegradation kinetics expected to occur in natural environme
21、ntal systems. This method is designed to determine the primary biodegradation in a continuously operating test system simulating a river. Before conducting this test, it is necessary to have information on the biodegradability behaviour of the test compound (e.g. at usual test concentrations in stan
22、dard biodegradation tests) and, if possible, on abiotic degradability or elimination (e.g. photolysis, adsorption or stripping) under conditions which are comparable to those of the river model and relevant physico-chemical data (e.g. water-solubility, adsorption coefficient K oc ) so as to properly
23、 plan the experiment and interpret the results.
