ANSES was seized on January 28, 2019 by DGAL for a request for scientific and technical support on the protection measures for residents during the use of plant protection products.
The conclusions are as follows:
Risk assessment for Human health before placing products on the market
It is recalled that a risk assessment is always conducted during the evaluation of the applications for authorisation. The methodology currently used in the assessment of plant protection product dossiers is based on EFSA guidance document (EFSA, 2014). For residents, EFSA’s guidance document currently describes an assessment methodology that covers spray application only. For other methods of application, a dedicated evaluation methodology should be used. EFSA will update the guidance document in early 2021.
As part of the risk assessment, when the estimated exposure including the risk management measures (distance and drift reduction device) is greater than the reference toxicological value (AOEL or AAOEL), the approval is not granted.
Measurement campaigns in the air and a biomonitoring study of residents are currently underway.
Risk management measures
To limit the exposure of residents during or after spraying, the establishment of safety distances to the occupied buildings and unbuilt areas adjacent to these buildings is recommended. They should be at least equal to the distances introduced in the risk assessment for residents that are based on the type of crop and of material used, or greater, by precaution principle for products classified carcinogenic, mutagenic or toxic for the reproduction.
In order to limit the exposure of persons present during or after spray application, the establishment of safety distances from areas frequented by the public is recommended. Areas likely to be frequented by the public should be defined. The safety distance should be at least equal to the distances introduced in the risk assessment of bystanders that are based on the type of crop and the material used, or greater, by precaution principle for products classified carcinogenic, mutagenic or toxic for the reproduction.
Generalisation of drift-reduction devices (drift nozzles and / or appropriate equipment or application techniques) that would also limit environmental exposure is recommended.
Finally ANSES emphasizes the importance of training programs for farmers on good practices and the importance of programmes to inform residents and in particular the establishment of charters between farmers and neighboring populations.
