Abstract: Pesticide residue acute dietary risk assessment has attracted attention only recently. So far, JMPR is working on international acute dietary risk assessment while USA, UK, Netherlands, Australia and New Zealand are working on their national acute dietary risk assessments. Acute dietary risk is a function of acute or short-term toxicity and acute dietary intake. Acute dietary exposure can be calculated by a point or deterministic method as well as by a probabilistic modeling method. In the deterministic method the intake is estimated with the assumption of large portion consumption of a ‘high residue’ food. In addition, the method also includes a variability factor to allow for the elevated residue in some single units which may not be seen in composite samples. According to the different situation, JMPR defines as case 1, case 2a, case2b and case 3 to use related formula respectively to calculate the acute dietary exposure. China should conduct acute dietary risk assessment, China should adopt the JMPR deterministic method of acute dietary risk assessment before the high or moderately toxic pesticides are registered for use. This would involve the establishment of comprehensive food consumption database, food commodity properties database, and market residue monitoring database.
