Regulatory risk assessment of pesticide residues in air

Background information describing current approaches taken by different cou ntries to risk assessment in regard of pesticide residues in air is present ed with a view to stimulating discussion of the subject in order to identif y means for improving both the underlying science and administrative proced ures concerned. Fundamental regulatory objectives are explored, alternative guidelines for conduct of exposure evaluation, risk assessment and regulat ory decision making are examined and the basic components of the technical framework in which this complex work is carried out are discussed. The crit eria which are capable of being used for regulatory decision support are co nsidered with a view to questioning their feasibility for practical use and relevance for operation to provide a robust basis for regulatory risk asse ssment for plant protection products. Brief recommendations are given for a spects of discussion where attention should be focused.
