| Abstract | Street cooking, i.e. food carts, contributes significant amount of air pollution emission in Bangkok, especially particulate matter with the diameter size equal to or less than 2.5 micrometers (PM2.5). Smoke from these street cooking activities can be seen from distances in some cases. However, emission from street cooking has not been properly addressed in any previous studies. This study developed an emission inventory for street cooking in Bangkok based on data from the survey of the ten roads and projecting to total roads in Bangkok based on the ratio of roads with and without street cooking in Bangkok using ArcGIS to estimate total PM2.5 from cooking emission for the base year of 2020. The average emission of PM2.5 from ten roads was 20.4 g/hr-km with an average operation hours of 8 hours per day. Thus, the PM2.5 emission per the road length in Bangkok was estimated as 59.6 kg/yr-km. Based on the survey data, fifteen percent of total road lengths in Bangkok has street cooking. Thus, total PM2.5 emission from street cooking was estimated in 2020 as 0.18 Gg/yr. Further improvement of emission inventory is still required to produce more accurate estimation for modeling inputs. Further in this study, the roads with street cooking in Bangkok showed higher concentration of PM2.5 than the roads without street cooking. The range of 10-20 μg m3 ⁄ increases in PM2.5 concentration was observed between roads with and without street cooking. The policy on controlling emission from street cooking should be considered, especially during the high PM2.5 concentration period since the data from this study showed that street cooking contributed significantly to total emission and concentration of PM2.5 in Bangkok. |
