The combustion of biomass and coal significantly contributes to the total health burden due to the emission of gaseous pollutants and particulate matter. To determine the personal exposure related to beehive coal stove cooking in Hanoi, an assessment study on 120 females in three wards (Tran Hung Dao, Phuc Tan, and Chuong Duong) of Ha Noi city, Viet Nam was conducted. Personal and ambient concentrations of and CO (upwind, nearsource, far-source) were simultaneously measured twice a day at each household by PATS++ equipment developed by Berkeley Air Monitoring group. The concentrations of in the three wards were in the range of 10-186, 12-441, 9-59, 3-271, and 9-260 µg/m3 while those of CO varied from 100-3,000, 300-260,000, 200-29,000, 300-255,000, and 2,000-36,000 µg/m3 , for upwind, near-source, far-source, indirect exposure, and direct exposure samples, respectively. The estimated COHb% for the directly exposed group was higher than the indirectly exposed group in the three wards. Consequently, the directly exposed group was suffering a higher risk. All directly exposed respondents and 75 % of indirect ones were experienced COHb% calculated in blood exceeding the safe threshold for the health of WHO guidelines. There has been increased risk for both exposed groups if the coal beehive stove placed indoor. The calculated levels of incremental life cancer risk (ILCR) posed by in the three wards varied from to daily, indicating moderate cancer risk to the community that should be studied further to protect public health. | Study on the health impact from beehive coal stoveusage in households in Hoan Kiem Ha Noi
