This study aims to describe respiratory symptoms and exposure to PM2.5 among adults exposed to household air pollution from traditional cookstoves using biomass fuel in Can Giuoc district, Long An province from August 2017 to August 2018. This descriptive cross-sectional study was conducted among 137 adults in 80 households using traditional cookstoves with biomass fuel. We randomly chose 32 people who used traditional cookstoves to measure individual air pollution exposure. The results show that the percentage with respiratory symptoms of cough, productive cough, shortness of breath and wheezing in the group of 137 adults is 59.9%, 39.4%, 38.7%, and 33.6%, respectively. Eye pain, runny nose, stuffy nose and coughing are the most common symptoms occurring during cooking with 56.2%, 47.5%, 44.5% and 41.6% recorded respectively. The mean PM2.5 concentration recorded by monitoring personal exposure among 32 people who directly cooked was 39.725µg/m3 while the mean CO concentration is 1.11 ppm. The PM2.5 concentration of 78.1% of the subjects under study exceeded the standards set by the WHO. Therefore, it is necessary to raise awareness about the harmful effects of biomass exposure from traditional cookstoves on respiratory health and plan for strategies to reduce biomass exposure.
