It results from the rise of the public environmental awareness and concern at home environmental quality.
(二) Current air quality conditions
Yun Chia Air Quality Region, As for the PSI>100 rate is 0.85%, that air quality adverse event day is 28 station day. Since 1994, the best year for air quality.Till 2013, air quality affected by the particulate matter. The PSI>100 rate is 2.96% Bad than last year (0.85%). However, the overall air quality in the Yun Chia air quality region remain to improve air quality trends.
As for Chiayi city in this year (October), that air quality adverse event day is 5 station day (Particulate 4 station day；Ozone 1 station day). Rate is 1.36%, which less than 2.19%.
