Abstract

As a result of the survey on the emission status of fluorine-based chemicals in Korea, 13 kinds of substances, including hydrogen fluoride (91%) and perfluorocarbons (5%), were emitted in workplaces. By regional groups, about 98% was emitted in the Gyeongbuk, Gyeonggi and Chungcheong regions, and about 98% in three sectors of industry related to manufacture of electronic parts, chemicals and non-metallic mineral products. The detection status of PFOS and PFOA in domestic main rivers was continuously detected in the Nakdong River, the Geum River and the Anseong Stream estuary with high fluorine-related chemical emissions, and four sites of PFOS and two sites of PFOA were detected for the first time in 2021. PFOS and PFOA were continuously detected in relatively high concentrations in the rivers where there were many semiconductor and display related sectors of industry.

국내 불소계 화학물질의 배출현황 조사결과 Hydrogen fluoride(91%)와 Perfluorocarbons(5%) 등 13종의 물질이 사업장을 통해 배출되었고, 지역별로는 경북, 경기, 충청권 지역에서 약 98%, 업종별로는 전자부품, 화학물질, 비금속 광물제품 제조업 관련 3개 분야에서 약 98%를 배출하였다. 주요 수계에서 나타나는 PFOS·PFOA의 검출 현황은 불소계 화학물질 배출량이 많은 낙동강 수계, 금강 수계, 안성천 하구언 지점에서 지속 검출되었으며, 4개의 PFOS 지점과 2개의 PFOA 지점은 2021년 처음으로 검출되었다. 반도체와 디스플레이 관련 업종이 많은 수계 지역에서 PFOS 및 PFOA가 비교적 높은 농도로 지속 검출되었다.
