  • Title: Cumulative dietary exposure assessment of pesticides that have acute effects on the nervous system using SAS® software.
    Author: European Food Safety Authority (EFSA), Dujardin B, Bocca V.
    Journal: EFSA J; 2019 Sep; 17(9):e05764. PubMed ID: 32626423.
    Abstract:
    Retrospective dietary exposure assessments were conducted for two groups of pesticides that have acute effects on the nervous system: brain and/or erythrocyte acetylcholinesterase inhibition, and functional alterations of the motor division. The pesticides considered in this assessment were identified and characterised in the scientific report on the establishment of cumulative assessment groups of pesticides for their effects on the nervous system. The exposure assessments used monitoring data collected by Member States under their official pesticide monitoring programmes in 2014, 2015 and 2016 and individual food consumption data from 10 populations of consumers from different countries and from different age groups. Exposure estimates were obtained for each group of pesticides by means of a 2-dimensional Monte Carlo simulation, which was implemented in SAS ® software. Results were validated against exposure estimates obtained by the Dutch National Institute for Public Health and the Environment (RIVM) using the Monte Carlo Risk Assessment (MCRA) software. Both tools produced nearly identical results and minor differences were mainly attributed to the random effect of probabilistic modelling. The exposure estimates obtained in this report are used in the final scientific report on the cumulative dietary risk characterisation of pesticides that have acute effects on the nervous system. The latter combines the hazard assessment and exposure assessment into a consolidated risk characterisation including all related uncertainties.
