DAILY BULLETIN
for air quality in the country
within the period from 00:00 to 24:00, 23.03.2017

The daily bulletin contains information about the levels of certain key parameters, characterizing air quality, in accordance with the national and European legislation: fine particulates (PM10), sulfur dioxide, nitrogen dioxide, carbon monoxide and ozone. Only registered exceedances of these pollutants are published. Information on norms for the content of pollutants in the ambient air, according to the national and European legislation, and information on the health effects of air pollution, is published on the website of the ExEA http://eea.government.bg/bg/output/daily/norms-air.doc.

Information to alert the population
In case of exceedances of the alert threshold for sulfur dioxide, nitrogen dioxide and ozone, information is provided to the population in accordance with "Instruction for informing the population in the case of exceedance of the established alarm thresholds and indicators". The last recorded exceedances of the alert thresholds for sulfur dioxide, nitrogen dioxide and ozone in ambient air are posted on the website of the ExEA http://pdbase.government.bg/airq/alarm-en.jsp.

Other information bulletins
Information on the levels of total dust, PM10, PM2.5, benzene, lead aerosols, arsenic, cadmium, nickel, polyaromatic hydrocarbons and some country-specific pollutants such as ammonia, phenol, carbon sulphide and others is presented in the quarterly bulletins and the National report on the state of the environment http://eea.government.bg/en/output/index.html.

Measures for air quality improvement
In the settlements with air pollution problems municipal programs have been developed for reduction of atmospheric pollutants levels and achievement of the standards. Settlements and pollutants, for which municipal programs for air quality improvement are developed, have been published on the website of ExEA http://eea.government.bg/bg/nsmos/air/roukav/index.html.
