Abstract

|
|
This study provides a basis for research to establishing air quality standards in Gyeongnam. The trends and deviations in air quality concentrations and short-term environmental standards were analyzed. Furthermore, the regional standards and World Health Organization`s (WHO) air quality guidelines (AQGs) were taken into account. The annual average PM10 standard for cities anc counties ate 40㎍/㎥ and 30㎍/㎥ , respectively. SO2 and NO2 are achieving national standards and need to be strengthened to the minimum regional standard and WHO AQGs. The PM2.5 standard, which has not reached national standards, needs to be set at the level of national standards, and is also the target level for 2024 of the Gyeongsangnam and national PM2.5 management plans.
