Microplastics in food containers and biological samples
Jaehak Jung(정재학) 환경독성보건학회 2021 한국독성학회 심포지움 및 학술발표회 Vol.2021 No.5
Humans, who have been benefiting from plastics for a long time, will finally face the counterattack of plastics as they experience the COVID-19 Pandemic. Various masks and disposable food packaging used exceeded the processing capacity of each country. Eventually, various untreated plastics flow into the sea along the river, become secondary microplastics, and eventually become contaminated with various aquatic organisms. It will come up to the table. Even the soil was contaminated for a long time due to agricultural seeds and fertilizers that were used by making micro-encapsulated microplastics, and as a result, root plants (carrots, etc.) and fruits (apples, etc.). The discovery of microplastics in the size of microns shows that the world is contaminated with microplastics in a very wide range. Since 2018, KIAST which has been leading the microplastics testing service and standardization for the first time in Korea, has recently been providing testing services for food containers such as tea bags, paper cups, baby feeding bottles, and various seafood. It will be introduced the results of microplastics analysis on oysters samples in Korea and the intestines of dead penguins collected at the King George Island in the Antarctic. Among biological samples, microplastics testing is the most difficult, and it is a field that requires a lot of technology development in the future, and a lot of research is needed for human risk assessment, so it is a situation that requires great interest and collaboration among global researchers.
