MAIN SOURCES OF POLLUTION IN BURGAS

  • Car traffic is the main source of air pollution in big cities. Significant amounts of nitrogen oxides and CO emissions are emitted by cars, as well as a large part of the amounts of particulate matter. Larger dust particles consist of dust suspended from roads and streets, while the exhaust gases of cars emit mainly fine dust particles. Between 80 and 90% of nitrogen oxide emissions are due to road traffic. In fact, car traffic is a source of air pollution all year round.
  • Domestic heating with wood and coal can be a significant source of emissions (fine dust particles, benzene) in the cold winter days. Not all residential complexes in Burgas are connected to a central heating system. In the city center, unheated residential complexes and in the surrounding villages, wood heating is the most common method of domestic heating. These sources can contribute a significant share of fine particulate matter emissions.
  • Lukoil Neftochim Burgas AD is the largest refinery in the country. Refineries can be a source of a wide range of pollutants (fine dust particles, hydrocarbons, nitrogen oxides, sulfur dioxide, hydrogen sulfide), both from production processes and from accidental emissions from leaks and from the tank farm.
  • Construction and repair activities are a source of pollution with dust and fine dust particles. Dust generated from construction sites or non-paved roads is re-distributed by air turbulence created by cars or wind and can become an environmental problem. The main part of the dust is coarse particles that are deposited near the roadway (within 10 to 20 meters). Less than 10 percent of the dust remains suspended as fine dust particles (PM10) and contributes to air pollution on a larger scale.
  • Industry – on the territory of Burgas operate several industrial enterprises, as they also contribute to air pollution, including fine dust particles.
  • The main air pollutants in urban areas are nitrogen oxides (especially NO2), originating from internal combustion engines and particulate matter, the source of which is domestic heating, exhaust gases from cars and particulate matter on the road surface.
