Point AA 01, dist. Izgrev, Krumovgrad

Point AA 01, dist. „Izgrev", Krumovgrad - Measurement of particulate matters with size up to 2.5μm, and up to 10μm (measured in real time). Separately are performed measurements for precipitated dust – data are gathered manually, and so it is not possible to present them on a real time plot.
Red lines on the plot are presenting limit values for particulate matters in the atmosphere, i. e. as following:

- Average Annual Limit for human health preserving – for particles with size up to 2,5 µm – from 25 µg/m3 (presented in the plot in µg/m3, which is corresponding to value from 0,025 µg/m3); - Average Day and Night Limit for human health preserving – for particles with size up to 10 µm – from 50 µg/m3 (presented in the plot in µg/m3, which is corresponding to value from 0,05 µg/m3)

Those particulate matters limit values are set in Ordinance No. 2, from 15.07.2010 – for limits for sulfur dioxide, nitrogen dioxide, particulate matters, lead, benzene, carbon monoxide, and ozone in the atmosphere (published in State Gasette 58 from 30.07.2010, valid from 30.07.2010)
