User manual for FOCUSSPIN version 3.3

In the EU and Dutch national registration procedures for plant protection products, fate models and scenarios are being used to assess the environmental risks of these products. For each model application, data on the physico-chemical properties of the substances are required. The software tool SPIN has been developed to store substance properties in a common database that can be accessed by the different model applications. This facilitates the use of these model applications for a specific substance. This user manual describes the use of FOCUSSPIN version 3.3, that can be used in combination with the EU FOCUS models (leaching to groundwater and exposure in surface water). FOCUSSPIN version 3.3. can also be used in combination with the new versions of national exposure assessment tools GeoPEARL (leaching to groundwater), DROPLET (drinking water) as well as the current version of GEM 3.3.2 (emission from greenhouses).
