서울의 대기질현황(2021)
1. 대기오염측정망
도시대기 측정망: 인구밀집지역의 대기오염도 및 환경기준 달성여부를 파악하여 대기질 개선 및 환경시책에 활용할 목적으로 운영하는 측정망으로 서울시 각 구별 1개소씩 총 25개의 측정소가 있다.
도로변 측정망: 자동차 통행량과 유동인구가 많은 도로변의 대기질 파악을 목적으로 15개의 도로변 측정소를 운영하고 있다.
| | Research Institute of Public Health and Environment of Seoul Metropolitan Goverment operates a network of air monitoring stations that measure fine particulate matter and other air pollutants. This indicator reports on the concentration of fine particulate matter from 2004-2020 and compares it to the South Korea Air Quality Standards established by Ministers of the Environment. |
Fine particulate matter: Solid or liquid particles floating in the air are called particluate matter. The smallest of these particles(those that are 2.5 microns or less in diameter, or less than 1/20th the width of a human hair) are called fine particluate matter(PM2.5). Fine particluate matter comes from many natural and huamn activites, includeing wildfires and emission from prescribed burning, forestry operations, residential woodstoves, and transportation.
Be Harmful to humans: Exposure to fine particlulate matter has been associated with several serious health effects including heart and lug disease. Both shor-term(24-hour) and longer-term(a year or more) exposure to fine particluate matter can have negative effects on human health.
Fine Particluate Matter(PM2.5): South Korea Ambient Air Quality Stnadard
| National ambient air quality Standard | Level |
|---|---|
| Yearly | 15ug/m3 or less |
| 24-hour | 35ug/m3 or less |
The map below summarises South Korea Ambient Air Quality Standard achievement status for fine particluate matter in Seoul. air zones, as well as both the annual and 24-hour PM2.5 levels at individual monitoring stations. Summaries are given for each monitoring station where sufficient data was available for the reporting period.
