ULAANBAATAR CITY’S AIR POLLUTION – SOURCE APORTIONMENT - MANAGEMENT S.Lodoysamba, National University of Mongolia 0
Contents Air pollution of Ulaanbaatar City, What is main sources of pollution, Management of mitigation of UB air pollution 1
Management of air pollution mitigation • Starts from measurements, • Air pollution concentration, • Identification and apportionment of pollution sources, • Modeling, • Health impact study, • Air pollution mitigation scenarios, • Health benefit calculation • Planning a target, • Activity • Monitoring • Ends with measurement. 2
Main Air Quality Indicators - Sulfur Dioxide (SO2) - Nitrogen Dioxide (NO2) • PM (Particulate Matter) PM10 • PM 2.5 - Carbon Monoxide (CO) - Ozone (03)
Methodology • Position of sampler: UB City- Nuclear Research Center Zuun Ail 3 Horoolol • Duration: 2004.10 – 2009. 6 • Flow rate of sampler: 16 l/мin (18-14) • Height of sampling: 1.6м, 6m, 4m • Sampling frequency: Twice a week • Sampler: GENT Sampler with Polycarbonate filters • Type of analysis: PIXE • ВС measurement: Reflectometer • Number of samples: 400 (2004-2006) • Data interpretation was made using software EPA PMF1.1(USA) PIXE analysis were done in the New Zealand Institute of Geosciences and Nuclear Sciences, 30 elements are analysed

Conclusion 1 • Main pollution sources are: • PM10- Soil erosion, Combustion, Motor vehichle, Biomass burning, • PM2.5- Coal combustion, Motor Vehicle+Road dust, Biomass burning, Soil • Ulaanbaatar is most polluted capital city of the world; • @ 50% of PM concentrations corresponds to ignition phase (cold start) and reloading of stoves; • There is presence of toxic elements: Hg, Ni, V, F, Cl, Br, As in the air; • Pb in the air is below the standard; • AQI is 82 (Moderate) in the Central area and more than 200(Very unhealthy) in the Ger areas;
Gases 39
Conclusion 2 • PM Emission can be reduced more than 99% using raw coal, • The PM emissions are so low that for much of the time the improved stove substantially cleans the ambient air that passes through it. The chimney gases are usually cleaner than the outdoor air.
