Among the prerequisites for obtaining approval for a biocidal active substance or product (active ingredient plus environmentally-relevant co-formulants) under the Swiss Biocidal Products Regulation (VBP) and the regulation 528/2012/EC is evidence of safety for the environment. Different environmental compartments are taken into account: waste-water treatment plants, surface waters including sediments, groundwater, soil and air.
Using data for the active substance, co-formulants (formulation materials) and products, potential emissions into environmental compartments are calculated, based on defined environmental scenarios. Models are used that are also applicable to the approval process for pesticides (e.g. FOCUS PEARL for calculating groundwater concentrations). In addition, it is important to take specific national and regional environmental factors (e.g. climate and soil types) into account during the risk assessment.
