摘要
目的通过观察在不同艾灸装置内艾燃烧生成细颗粒物(PM_(2.5))和多种气体的排放量,进一步讨论艾灸疗法的安全性。方法试验选取18个同一批次的1 g艾条在3种艾灸装置内燃烧,采用激光粉尘仪、气体检测仪进行检测。18个艾条样品随机分为自然暴露燃烧组、灸筒燃烧组、灸筒加过滤罩组,每组6个。将艾灸装置在密闭玻璃房内点燃,对其产生的PM_(2.5)质量浓度,CO、SO_2、NO_2摩尔分数进行实时监测,取各项指标的峰值。结果 3组艾条燃烧产生的PM_(2.5)、CO、SO_2有统计学差异,其中灸筒加过滤罩组的PM_(2.5)质量浓度低于灸筒燃烧组和自然暴露燃烧组(P<0.05),且灸筒加过滤罩组CO、SO_2的摩尔分数显著低于自然暴露燃烧组、灸筒燃烧组(P<0.05),灸筒加过滤罩组3项指标在3组内均为最低水平。燃烧过程中PM_(2.5)质量浓度峰值为灸筒燃烧组>自然暴露燃烧组>灸筒加过滤罩组;CO、SO_2摩尔分数峰值为自然暴露燃烧组>灸筒燃烧组>灸筒加过滤罩组。环境中NO_2摩尔分数的监测值并未因艾燃烧而增加。结论不同装置内艾燃烧所产生的PM_(2.5)以及CO、SO_2有差异,艾灸装置加过滤罩可以降低艾灸环境中的PM_(2.5)质量浓度和CO、SO_2摩尔分数,可以避免艾灸过程中产生的烟雾危害。
Objective By observing the emission of particles and various gases under different combustion conditions during moxibustion,to further discuss the safety of moxibustion therapy. Methods Eighteen moxa sticks（ 1 g） from the same batch were put into three types of moxibustion devices and burnt out,which was detected by laser measuring dust and gas detectors. These moxa sticks were randomly divided into natural exposure group,moxa cylindrical device group and moxa cylindrical device with filter group（ n = 6 in each group）. Ignition was made in the sealed glass room,and PM_（2.5）（ Particulate Matter 2. 5） mass concentration,CO,SO_2 and NO_2 emissions were constantly monitored,and peak values of each one were noted. Results There were statistic differences among the three groups in PM_（2.5）,CO and SO_2 levels. The concentration of PM_（2.5） and the emission of CO and SO_2 in group of moxa cylindrical device with filter were the lowest in the three groups（ P〈0. 05）. Moxibustion did not affect the content of NO_2. The peak concentration of PM_（2.5） in descending order was： moxibustion cylindrical device group natural exposure group moxibustion cylindrical device with filter group. The peak emission values of CO and SO_2： natural exposure group moxibustion cylindrical device group moxibustion cylindrical device with filter group. Conclusion There were differences in the emission of PM_（2.5）,CO and SO_2 in different devices. Controlling the moxa burning conditions can reduce the emission of PM_（2.5）,CO and SO_2. Therefore physical barrier measures should be taken to effectively reduce the concentration of PM_（2.5） in moxibustion sites and avoid moxa smoke.
