In accordance with Regulation (EC) No. 1107/2009 of the European Parliament and the Council, the FOCUS Degradation Kinetics Workgroup developed recommendations for calculating degradation kinetics in the registration process. FOCUS degradation kinetics consists of standardized procedures for calculating degradation rates for parent and metabolites from laboratory soil and water studies, field studies and water sediment studies.
Two types of kinetic endpoints are calculated from the degradations rates: Persistence endpoints (used as trigger values for higher tier experiments) and Modeling endpoints (used for estimating Predicted Environmental Concentrations (PECs) in soil, surface water, groundwater, and sediment). These endpoints are an important part in registration process of plant protection chemicals in the EU.
Waterborne is experienced with performing degradation kinetics following the FOCUS guidelines for laboratory, field, and water sediment studies using Modelmaker and Excel®, the software recommended by the Workgroup. We also have expertise in using newer software such as KinGUI (developed by Bayer CropScience) and CAKE (sponsored by Syngenta) for degradation kinetics.
