Also was conducted questionnaire-based survey of children for respiratory illness-related symptoms in 170 households in 15 mountain villages.Results: People in all 170 houses use biomass for cooking and heating. We found high levels of indoor air pollution in the houses, and it was confirmed with high levels of PM2.5 in the air of the houses. The maximum level of PM2.5 was 116.56 μg/м3 against in lowland was 0.178 μg/м3. The average level of PM2.5 was 48.7 μg/м3 against in lowland was 1.03 μg/м3. We also found higher values of carbon monoxide (CO ppm) 10.23 ppm against in lowland 1.5 ppm. The frequency of cough during heating period in highlander’s children was 48.2% against in lowland children was 18.1%, pneumonia in highland and lowland children were 9.52% and 2.8% and confirmed infection of respiratory tract in highland and lowland children were 73.21% and 39.5%. The PM2.5 levels were significantly greater (p<0.05) in mountainous households where children had respiratory symptoms compared to lowland households.Conclusion: The high level of indoor air pollution possibly can be cause of respiratory illness.
