Five temples, each a different size, were selected for this study. Two of the temples were located in Taichung City (in central Taiwan), and three were in Tainan City (in Southern Taiwan). Aerosols smaller than 10 microm aerodynamic diameter (PM(10)) were collected by using personal collection samplers during pilgrim days (the first and fifteenth day of each lunar month) and normal days (all other days). Regression analysis showed that about 1.6 microg/m(3) of PM(10) contributed to the workers' exposure in the temples for each joss stick increase in the censer. The concentrations of total polycyclic aromatic hydrocarbons (t-PAHs) and carcinogenic PAHs (car-PAHs) on pilgrim days were higher than those on normal days. Mean concentrations of urinary 1-hydroxypyrene (1-OHP) in the pre-shift and post-shift workers of the five temples on normal days were 1.20 and 1.61 microg/g creatinine, respectively. Furthermore, the post-shift concentrations of 1-OHP in the workers of temples on pilgrim days were all higher than those of the workers of corresponding temples on normal days. Significant relationships between the urinary concentrations of 1-OHP and the exposure concentrations of pyrene, total PAHs and BaP(eq) were found in the workers of the temples. Results of linear regression showed that the increase of unit concentration (1 ng/m(3)) of pyrene led to a 0.05 microg/g creatinine increase of urinary 1-OHP, while the increase of unit concentration (1 ng/m(3)) of BaP(eq) resulted in an increase of 0.03 microg/g creatinine of urinary 1-OHP.
本研究选取了五座大小各异的寺庙。其中两座寺庙位于台中市（台湾中部），三座位于台南市（台湾南部）。在朝圣日（农历每月初一和十五）和正常日（其他日期），使用个人采集采样器收集空气动力学直径小于10微米的气溶胶（PM10）。回归分析表明，香炉中每增加一支香，约1.6微克/立方米的PM10会导致寺庙内工人的暴露量增加。朝圣日的总多环芳烃（t-PAHs）和致癌多环芳烃（car-PAHs）浓度高于正常日。正常日五座寺庙班前和班后工人尿中1-羟基芘（1-OHP）的平均浓度分别为1.20和1.61微克/克肌酐。此外，朝圣日寺庙工人班后的1-OHP浓度均高于相应寺庙正常日工人的浓度。在寺庙工人中发现尿中1-OHP浓度与芘、总多环芳烃和苯并[a]芘当量（BaP(eq)）的暴露浓度之间存在显著关系。线性回归结果表明，芘单位浓度（1纳克/立方米）的增加导致尿中1-OHP增加0.05微克/克肌酐，而BaP(eq)单位浓度（1纳克/立方米）的增加导致尿中1-OHP增加0.03微克/克肌酐。
