0ULAANBAATAR CITY’S AIR POLLUTION – SOURCE APORTIONMENT - MANAGEMENT S.Lodoysamba,National University of Mongolia
1Contents Air pollution of Ulaanbaatar City, What is main sources of pollution,Management of mitigation of UB air pollution1
2Management 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 calculationPlanning a target,ActivityMonitoringEnds with measurement.2
6Methodology Position of sampler: UB City- Nuclear Research Center Zuun Ail3 HoroololDuration: –Flow rate of sampler: 16 l/мin (18-14)Height of sampling: 1.6м, 6m, 4mSampling frequency: Twice a weekSampler: GENT Sampler with Polycarbonate filtersType of analysis: PIXEВС measurement: ReflectometerNumber of samples: 400 ( )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

32Conclusion 1 Main pollution sources are: PM10- Soil erosion, Combustion, Motor vehichle, Biomass burning,PM2.5- Coal combustion, Motor Vehicle+Road dust, Biomass burning, SoilUlaanbaatar 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;
48Conclusion 2PM 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.
50Air Pollution Concentration reductions due to emission reduction scenarios. PM emissions needs to be reduced with about 94% to reach Mongolias own air quality standards for PM10:
51Annual Health Benefits From Abatement Scenarios - benefits of different solutions accrue at different times.
52The Cost of Delaying Short Term Measures: The decisive Argument for the project!
53Some of the Lessons:Paid off to make a full-scale AQM study.Most critical argument for getting actual the projects through:- Health Impacts (physical & economic).- Cost effectiveness of abatement options, Cost of Inaction.- Comparing concentration levels with other countries/cities.
