| Abstract |
Researchers in all fields of engineering and science understand nanomaterials as materials smaller than 1um. Among them, especially nanotechnology researchers refer to substances smaller than 100nm as nanomaterial. Though it is generally defined based on its size, but from an institutional perspective for chemical safety management, it is distinguished from non-nanomaterials with more complex criteria such as number-based size distribution fraction of nano-sized particle in the product. The study of nanomaterial risks has been going on for more than a decade. Nanomaterial is not a new chemical, but a new classification system depending on the properties of the chemical. When a chemical exists in a finite form that exhibits a certain physically apparent size under certain conditions, we can define it as a nanomaterial or a non-nanomaterial. In terms of regulation, applying the management policy of chemicals to nanomaterial is a very complex issue that requires significant changes to the classification system of existing chemicals. Due to this importance, the specified safety regulation on nanomaterials has yet to be implemented, even though a substantial number of scientific and regulatory studies have been carried out. In December 2018 the European Union finally passed a revision of REACH which includes nanomaterials, and a related registration and evaluation of nanomaterials will begin in 2020. The U.S. and Canada, prior to registration and evaluation of chemicals, had implemented a reporting rule to investigate the current state of manufacture and use of nanomaterials. In this presentation, the research trends in nanomaterials will be explained from the institutional perspective of chemical safety management through a 5W1H way. "Why" suggests the need for institutional management of nanomaterials. "What" compares the scientific and legal definitions of nanomaterial and the differences by country. 'Where' shows the major uses of nanomaterial so far. 'When' describes the timing and main content of regulatory management of nanomaterial in major countries. 'Who' looks at stakeholders' interests in nanomaterial management and conflicts with each other's. ‘How' describes the framework of nanomaterial safety management. Finally, the regulatory roadmap is suggested for the implementation of nanomaterial in the chemical safety management system. |
