Air quality in Canada and the OECD

(캐나다와 OECD 국가들의 대기질 현황)
□ 보고서는 캐나다의 대기질 수준을 OECD 고소득국 31개국과 비교 평가한 연구 결과를 보여줌
 - 주요 오염원으로 미세먼지(PM2.5), 지표면 오존, 질소산화물(NOₓ)을 선정하고, 2019~2022년 데이터를 바탕으로 노출 수준, WHO 기준 초과 여부, 건강 부담(DALYs)을 종합적으로 분석함

□ 캐나다는 종합 점수 84.0점으로 8위를 차지함
 - PM2.5 평균 노출에서 공동 1위를 기록해 미세먼지 측면에서는 최고 수준의 공기질을 보임
 - 그러나 오존 노출과 이에 따른 건강 위험에서는 중간 수준(노출 12위, 건강위험 15위), 질소산화물 노출에서는 14위를 기록하여 일부 개선 가능성을 시사함

□ 칠레, 한국, 이스라엘은 모든 지표에 대한 데이터가 없어 본 연구 대상에서 제외됨
