Probabilistic exposure assessment of operator and residential non-dietary exposure

This paper discusses the potential role of probabilistic non-dietary exposure and risk assessment in the regulatory processes for pesticide products, Regulatory decisions regarding operator or consumer exposure to pesticide products have traditionally been based on deterministic exposure assessments. With the development of computer modelling and exposure databases, the submission of non-dietary exposure probabilistic assessments are imminent. The current status of non-dietary probability analysis to support regulatory risk management decisions is provided with a case study presented to illustrate issues regarding the use of probability analysis for regulatory non-dietary risk assessment. The development of a guidance document for the use of non-dietary exposure probability analyses for regulatory purposes is proposed, (C) 2001 British Occupational Hygiene Society, Published by Elsevier Science Ltd.
