A perspective of pesticide residue variability and acute dietary risk assessment

The question of the variability of pesticide residues and acute risk assessment has arisen in the context of the work of the European Commission's Scientific Committee for Plants (SCP). A brief outline is presented of European Community legislation on pesticide residues and the authorization of plant protection products. It is stated that although chronic risk assessment is systematically carried out in connection with the fixing of Community MRLs, the same has not applied for acute risk assessment. The reasons for this situation have been the absence of an agreed methodology, acute reference dose (RfD) and adequate dietary and residue data. It is stated that in the opinion of the Scientific Committee for Plants an acute risk assessment should be considered on a routine basis and that steps should be taken to ensure the availability of the necessary data. Possible implications for risk communication and the authorization of plant protection products in the EC are also discussed.
