Risk Assessment for Biocides

• Input parameter for ERA
• Emission pathways into environment
• Definitions (emission estimation, exposure and effect assessment, risk characterisation)

• ECHA guidance documents (Vol. IV, Part A&B):
• Information requirements (Part A)
• Introduction in Part B (i.e. input parameter and PEC-calculations)
• TAB August 2017 (agreed changes or amendments for the ERA)
• ESDs for the different Product Types (PT)

• Introduction of EUSES2.1.2
• EXCEL-sheets as an alternative

Training Session: EUSES2.1.2

• Introduction of EUSES2.1.2 and creation of training file

• Definition of intended uses
• Life cycle stages to be assessed: formulation, application, service-life
• Selection of the relevant emission scenarios
• Tonnage based / consumption based approaches

Training session: emission estimation

• Example calculation with EXCEL-sheets or EUSES2.1.2 for 2-3 scenarios in different PTs (e.g. disinfectants: PT1-4, preservatives: PT6-10 and insecticide: PT18 or repellent: PT19)

• Emission via sewage treatment plant (STP):
  
  
• calculation of PEC-values for STP, surface water, sediment, soil
  
  
• Release to soil:
  
  
• after application of slurry/manure on grassland or arable land (e.g. PT3/PT18)
• after leaching from treated surface (e.g. PT7-PT10)
  
  
• Calculation of PEC for groundwater
  
  

Training session: exposure estimation

Example calculations with EUSES2.1.2 and EXCEL-sheets

• Effect assessment and Risk characterisation
  
  • effect assessment: PNEC derivation with EUSES and equilibrium partitioning method for sediment and soil
  • environmental risk characterisation
