Abstract | 寺廟焚香在燃燒過程中,含有氣相之醛酮化合物與金屬顆粒在寺廟空間中,對民眾或廟方工作人員造成健康上的影響。2018年採集南投縣兩間A與B寺廟各7天及9個天之焚香空氣樣本,醛酮化合物與氣膠樣本分別是利用矽膠吸附管與Moudi 四階個人式高流量空氣採樣器採集8小時,而醛酮化合物與金屬元素則是分別利用高效能液相層析儀紫外線偵測器(HPLC/UV)及感應耦合電漿源子發射光譜儀(ICP/OES)進行分析。在焚香過程中,A寺廟最高的質量濃度為粒徑<1.0m之12.643.99 g/m3,而粒徑PM10-2.5對於總懸浮粒徑質量比值為16.65%5.89%,PM2.5-1和PM1分別占總懸浮粒徑質量之18.11%和46.08%。而B寺廟最高的質量濃度為粒徑2.5-1.0m之7.623.02 g/m3,而粒徑PM10-2.5與與PM1對於總懸浮粒徑質量比值分別占17.39%和52.19%。B寺廟有推廣減香活動,其A寺廟總懸浮微粒是B寺廟之1.42倍,且不論寺廟是否減香,其焚香燃燒之粒狀物皆以奈米粒狀物(PM粒徑<1m)佔總懸浮微粒約50%,顯示對人體危害值得注意。在有害重金屬元素濃度方面,A寺廟之濃度最高為鋅(5.05 g/m3)、鉛(0.32 g/m3)和錳(0.27 g/m3),而B寺廟最高為鋅(3.78 g/m3),其次是錳、銅和鉛,濃度約0.22-0.29 g/m3。醛酮類化合物之危害暴露方面,A寺廟之濃度最高為乙醛(13.056.19 g/m3)、甲醛(12.943.55 g/m3)和丙烯醛(8.815.06 g/m3),而B寺廟為甲醛(11.664.79 g/m3)、乙醛(6.203.01 g/m3)和對甲基苯甲醛(2.751.08 g/m3)。 在健康暴露風險評估方面,A寺廟與B寺廟之焚香中鎘、鈷、鉻、鎳、鉛、鋅與砷之致癌金屬在總懸浮微粒中的總致癌風險值為8.810-5及7.010-5。甲醛、乙醛及丙烯醛之暴露危害並未超過可接受之致癌風險值(10-6)。值得注意的是,寺廟工作人員的健康風險評估值顯示鉻、鎳、鋅與砷之重金屬均超過致癌風險值(10-6),表示寺廟焚香環境中是有潛在的致癌風險存在。因此,推動減香活動可以達到健康環境與經濟效應之雙贏之目的。
The health effects of aldehydes, ketones and metal-containing incense-particles on staffs at temples during incense burning periods. Samples were collected over 7 and 9 working days at A and B temple in Nantou County, 2018. Carbonyl compounds and aerosol samples were collected for 8 h using the solid sorbent tube and 4 impaction stages of Moudi Impactor, respectively. Carbonyl compounds and metal-containing particles were analyzed using a high performance liquid chromatography with UV detector (HPLC/UV) and an inductively coupled plasma with optical emission spectroscopy (ICP-OES).Measurement results show that the particles with the highest mass concentrations were PM<1.0 (12.643.99 g/m3) at A temple. The mass ratios of PM10-2.5 to total PM was16.65%5.89%. The PM2.5-1 and PM1 constituted 18.11% and 46.08% of the total PM mass, respectively. Particles with the highest mass by size were PM2.5-1 (7.623.02 g/m3) at B temple. The mass ratios of PM10-2.5 relative to total PM and those of PM1 to total PM were 7.39% and 52.19%, respectively. The mass of total particles at A temple was approximately 1.4 times higher than that at B temple because of incense reduction at B temple. Overall, the mass ratios of PM1 relative to the total particles 46.08 to 52.19%.The most abundant metal elements in all particle sizes on all sampling days were Zn (5.05 g/m3), Pb (0.32 g/m3) and Mn (0.27 g/m3) at A temple. The most abundant metal elements of all fractions were Zn (3.78 g/m3); these were follow by Mn, Cu and Pb with concentrations of 0.22 to 0.29 g/m3 at B temple. The formaldehyde, acetaldehyde, Acrolein and p-methyl benzaldehyde were identified during incense burning periods, the concentrations ranges from 2.75 to 13.05 g/m3. Cancer risks of carcinogenic metals (Cd, Co , Cr, Ni, Pb, Zn and As) in total particles were 8.810-7and 7.010-5 for staffs at A and B temple, respectively. The cancer risk of formaldehyde, acetaldehyde and Acrolein did not exceed the 10-6 acceptable level. Significantly, health risk assessment revealed that the risk values (Cr, Ni, Zn and As) for staffs were all above the guidelines of cancer risk (10-6) at two temples, indicating that there are potential cancer risk at the temples workplace during incense burning periods. Therefore, the policy of incense reduction might achieve healthy environments and economic win-win goal.
