Abstract: In Japan, the revised Health Promotion Act totally came into force in April of 2020 and has made smoking within buildings a punishable offence. However, this law hasn‘t provided clarification on the presence of secondhand smoke outdoors. The aim of this study was to examine the effects of outdoor secondhand tobacco smoke on school children. We generated artificial tobacco smoking at the test point (TP) near an outdoor bus stop, and measured the particulate matter 2.5 (PM2.5) level of both the TP and the surrounding area. After the generation, the PM2.5 levels increased spontaneously at a distance of 3 meters from the TP within 11 minutes, with the maximum level of 316 μg/m3. The level of PM2.5 was approximately 200 μg/m3 within a distance of 6 meters from the TP and rose above the environmental standard level set by the Japanese Ministry of the Environment at the 14-meter point. Furthermore, we generated artificial tobacco smoking in the TP near the entrance of a building. The PM2.5 level at a distance of one meter from the TP increased to 1143 μg/m3 after 6 minutes of smoke generation. Tobacco smoking flowed into the building when the door was opened, and the PM2.5 levels at the 6, 13, and 21meter points rose above the environmental standard level as well. School children near a bus stop and in a building that had a smoking point outdoor near its entrance, had the possibility of being exposed to a high level of secondhand smoke outdoors.
