БНСУ-ын Үндэсний судалгааны сангийн үндэсний стратегийн төслийг дэмжих санхүүжилтийн хүрээнд Эхва Их Сургууль (EWHA)-ийн судлаач профессоруудтай хамтран хэрэгжүүлсэн УБ хотын нарийн ширхэглэгт тоосонцрын сорьц цуглуулалтын ажлыг хийж гүйцэтгэсэн. Төслийн зорилго нь УБ хотын гэр хороололын болон хотын төвийн бүсийн агаарын нарийн ширхэглэгт тоосонцорт агуулагдах химийн бохирдлын агуулгыг тодорхойлон харьцуулахад оршино.
This project will identify actual exposure to toxic metals including lead, nickel, cadmium, chromium, arsenic, and organic species (Poly Aromatic Hydrocarbon (PAH) among children who live in Ulaanbaatar city with a high level of air pollution using scientifically proofed methods. The project team will recruit 50 children in the study as permission of children and their parents. Then we will measure particulate matters at the breathing zone of the children for the 24 hours of a day by personal air sampling method. As this measurement, we will determine the correlation between the daily exposure level of toxic chemicals in PM among children in winter caused by air pollution.
Түлхүүр үгс:The concentration of fine particulates in Ulaanbaatar (Ub), Mongolia has been lowered over the past 10 years, as a result of the city's efforts in implementing environmental control measures. Yet, the particulate concentration level in Ub remains high as compared to other urban areas globally. In order to further improve fine particulate air quality in the Mongolian region and design a more effective control strategy, an enhanced understanding of the sources and contribution of aerosol particulates along with their chemical compositions is necessary. In turn, relative contributions from local and transported sources on Ub need to be established, as this city is particularly influenced by sources from upwind geographic areas. Should critically synthesize information from across all available sources (challenges including obtaining the information and evaluating its quality). Apart from that, frequent or continuous measurements of air pollutant concentrations should always include measurements of meteorological parameters to describe the transport and dispersion of polluted air. Performance control of emission mitigation measures or strategies must be always accompanied by a monitoring strategy. That might also justify the need for continuously operated measurement stations and for temporary measurement campaigns or sites.

Түлхүүр үгс:Global awareness of ambient air pollution has been growing due to its great risk to public health. World Health Organization (WHO) reported that annual concentration of ambient particulate matter air pollution was increased globally by 8% during the recent five years. Ulaanbaatar, the capital of Mongolia, is reported to be one of the air-polluted cities in the world. Health effects of particulate matter air pollution have been reported in terms of mortality and morbidity of cardiopulmonary diseases, prevalence of respiratory symptoms and hospital admission. In Mongolia, air pollution has been reported to enhance urinary excretion of 1-hydroxypyrene in children, which is a biomarker for polyaromatic hydrocarbons (PAHs), byproducts derived from coal combustion exposure. Dashdendev et al. reported that carbon monoxide pollution contributed to the deterioration of lung function in Mongolian children.
Moreover, in Mongolia, in addition to its geographical feature as a basin that tends to trap polluted air, the increased consumption of solid fuels has contributed significantly to air pollution in Ulaanbaatar. Mass migration from the rural areas into Ulaanbaatar has risen over the last two decades, resulting in an increase in population and population density. Migrated people built ger, the traditional nomadic dwelling of Mongolians, in the perimeter of the urban area. The ger district is heavily dependent on solid fuels such as coal and wood as household fuel for heating and cooking. This causes air pollution that spans a considerably long duration in Mongolia, especially in the cold season. Air pollution in Ulaanbaatar has also been attributed to the heat-only boilers and coal fired thermal power plants. These sources of air pollutants have frequently caused Ulaanbaatar to be covered in smog in the cold season. In this study, determinate inorganic and organic compounds which is mainly emitted from combustion related sources and expected considerably effect on human health, in ambient particulate matter and to compare the performance parameter values are within acceptable ranges in spring and winter. At the same time, ambient particulate matter and aerodynamic particle size distribution measure, and the component of PM2.5 is analyzed to identifying the source of pollution (source appointment) in Ulaanbaatar to assess the impact of air pollution.
