Temple workers and traf fic policemen were significantly more exposed to 1,3-butadiene than controls ( p < 0.001). The urinary 1,3-butadiene metabolite, monohydroxy-butenyl mercapturic acid levels in expo sed group were larger than those in controls. 8-Hydroxy -2{u2019}-deoxyguanosine in leukocyte s (8-OHdG), DNA strand breaks, and DNA repair capacity measured by increases in gamma ray induced chromosome aberration, used as biomarkers of early biological effects, have been measured and were significantly larger in exposed workers than contro l subjects. So, temple workers and traffic policemen who are exposed to 1,3-butadiene from burning incense and automobile emissions in their workplaces, are more vulnerable to develop diseases such as cancer than controls.
