This paper describes the method and application of cumulative ecological risk assessment of multiple pesticides. Species sensitivity distribution (SSD) is a statistical distribution of difference in sensitivity to the toxicant among species. By utilizing SSD to compute the “potentially affected fraction of species” (PAF), a metric for assessing the impact on biodiversity, and applying mixture toxicity models, it is possible to calculate the cumulative risk posed by multiple pesticides. The paper also details the development a risk assessment tool based on Microsoft Excel, NIAES-CERAP, to facilitate the calculation process. In addition, the validation of risk assessment using laboratory toxicity testing and field ecological surveys was introduced, as well as the application of NIAES-CERAP in constructing a national ecological risk map in Japan and evaluating the effectiveness of eco-friendly agriculture.
