Dawoon Jung, Sora Yi, Sung Ji Yoon, Shi Jin Kim Jooyoung Park, Jongwoon Kim Recent scares involving health damage from exposure to chemicals in living environments, exemplified by the humidifier disinfectant accident, have increased people’s mistrust of biocidal products and household chemical products. Accordingly, the demand for tighter regulation, as well as better management of such products has also increased. The purpose of this study was to develop a methodology that utilizes cumulative risk assessment to comprehensively evaluate the risk of chemicals contained in household products, thereby enhancing the safety management of them. ◆ First, we recognized that cumulative exposure and risk assessment is used interchangeably with mixture exposure and 01 KEI Research Briefs risk assessment and aggregate exposure and risk assessment in Korea. Therefore, we came up with the terms cumulative exposure of a single substance and cumulative exposure of multiple substances to represent aggregate exposure and cumulative exposure respectively. Similarly, we defined cumulative risk assessment of a single substance and cumulative risk assessment of multiple substances to represent aggregate risk assessment and cumulative risk assessment respectively. Next, we reviewed the status of research related to cumulative risk assessment in Korea. Although studies on cumulative risk assessments have been active, most studies were limited to studies on single substance cumulative risk assessments. In addition, the results of the research did 01 KEI Research Briefs
