일회용 종이컵에서 발생하는 나노플라스틱의 생체 내 잔존량 측정

Abstract

In this study, an experiment was conducted to determine whether nanoplastics extracted from disposable paper cups that are easily accessible and widely used in daily life remain in vivo. In order to extract nanoplastics, water boiled at 95-100℃ was added to a disposable paper cup, and the extracted nanoplastics were observed with a digital microscope. To check whether nanoplastics remained in the body, 1mg/mL of nanoplastic was administered to mice, urine and feces were collected to measure the amount of nanoplastics discharged, and the gastric tissue of mice was collected to confirm the amount of nanoplastics remaining on the stomach. As a result, it was confirmed that a significant amount of nanoplastic in the disposable paper cup was extracted at high water temperature, and the amount of nanoplastic was discharged out of the body, but some remained in the body.
