Discussion of the practical training/homework

Emission estimation

• Definition of intended uses
• Lifecycle stages to be assessed: formulation, application, service-life
• Selection of the relevant emission scenarios

Practical training: emission estimation (homework)

• Example calculation with EXCEL sheets or Euses2.2.0 for 2-3 scenarios in different product types (for example disinfectants: PT1-4, preservatives: PT6-10 and insecticides: PT18 or repellent: PT19)

Exposure estimation (calculation of Pec-values)

• Emission via sewage treatment plant (STP)
• Calculation of Pec-values for STP, surface water, sediment, soil and groundwater

Practical training: exposure estimation (homework)
