Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October Training Session Product File Notes and Registration Reports Overview Submitted studies Labelling Exposure Risk assessment Example

Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October Training Session Product File Notes and Registration Reports Submitted studies see presentation of M. Guelton two remarks: Clearly indicate the units (e.g. 10 mg formulation/l or 10 mg active substance/l) because sometimes studies are carried out with the product but the endpoint is expressed in active substance Always mention the most critical endpoint, for algae this is most often the EbC50 and not the ErC50 value

Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October Training Session Product File Notes and Registration Reports Labelling Only labelling concerning ecotoxicology must be mentionned here Use the most critical acute endpoints for labelling (e.g.algae: EbC50) Most critical acute endpoint < 1 mg product/ l  R50 1 mg productl < Most critical acute endpoint < 10 mg/l  R51 10 mg productl < Most critical acute endpoint < 100 mg/l  R52 Most critical acute endpoint > 100 mg product/l  no ecotox classification

Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October Training Session Product File Notes and Registration Reports Labelling (2) R53 is assigned by default for a product with R50, 51 or 52 unless a biodegradability study reveals that this phrase is not necessary Safety phrases Professionals: S35-61 if R50 or 51 S61 if R52 Non-professionals: S29-56 if R50, R51 or 52 If studies on non target arthropods: the product has no unacceptable effects on e.g. Typhlodromus pyri

Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October Training Session Product File Notes and Registration Reports Exposure (of aquatic organisms) Excell sheet for cereals, maize = leafy crops, vegetables = grassland, herbicide in orchards in case of aquatic risk evaluation to be used for all ‘horizontal’ cultivated plants i.e. vegetables, grains, grassland To be used for herbicides Excell sheet for grapevine To be used for all ‘vertical’ cultivated crops i.e. grapes, small fruits, ornamentals, tomatoes, … Excell sheet for orchards To be used for apple, pear, … Excell sheets for hops To be used for hops

Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October Training Session Product File Notes and Registration Reports Exposure (2) PEC-calculations:  By formula in the excell-sheet  Input data: concentration of a.s. in the product, application rate, number of applications, interval, DT50  DT50 = 1000 unless data from water/sediment study are available  known DT50 for products with more than one a.s. :  if one a.s. is clearly more toxic than the other one: take the DT50 of the most toxic a.s.  if toxicity is related to both a.s., than take the worst case DT50

Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October Training Session Product File Notes and Registration Reports Risk assessment TER-calculation TER = EC50 / PEC Fish, daphnia: if TER > 100, then risk is acceptable Algue: if TER > 10, then risk is acceptable
