Objective To explore the correct appheation of risk assessment technology and provide scientific evidence for the establishment of limit standards for chemical hazards. Methods Based on the national and international latest progresses in this area, the risk assessment technology according to the risk assessment framework for different kinds of chemical hazards was analyzed. Results Based on the detailed introduction of the four aspects including hazard identification, hazard characterization, exposure assessment and risk characterization, this article fia＇ther described the selection and application of risk assessment technology for different kinds of chemical hazards. Conclusion Risk assessment technology has been internationally recognized. In practice, appropriate risk assessment technology should be applied to specific chemical hazard to provide scientific evidence for food safety related decision - making.
