Settlement /Station	1h LV [350 µg/m3]	24h LV [125 µg/m3]	1h LV [200 µg/m3]	24h LV [50 µg/m3]	LV (8h) [10 mg/m3]	Information threshold [180µg/m3]

Remark:

1. The automatic stations operate continuously. The AQ data from automatic stations are received in local and national databases by National Real Time Air Quality Information Network. The data from automatic stations are preliminary and they are not finally validated. The finally validated data will be published in the Annual Report for the state of environment.
