北京寺庙燃香空气污染研究

随着国内旅游业的发展及佛教、道教的兴盛,各地燃香量不断增大。为降低生产成本,劣质香在寺庙内大量使用。为了了解寺庙内由燃香引起的空气污染状况,本文对北京市区2座寺庙空气中的甲醛及可吸入颗粒物(PM10)浓度进行了测定与分析。结果表明:寺内甲醛浓度已达到或超过对人体健康影响的限值,其中香炉处的甲醛浓度最高,平均值高于0.67mg/m3,殿内和殿外的平均值高于0.08mg/m3;可吸入颗粒物PM10中以PM1.0和PM2.0为主(按计数浓度计),分别占87%和96%以上;燃香是寺庙空气可吸入颗粒物污染的主要来源。因此,对于长期暴露于燃香污染下的寺庙僧人、工作人员及朝拜者,其健康风险会有所增加。本文建议建立天燃香的制作标准,禁止含有过度有害化学成分的劣质香的生产和流通,以加强对寺庙僧人、工作人员及朝拜者的健康保护。

Experimental Study on Air Pollution due to Incense Burning in Beijing Temples

With the domestic tourism development and prosperity of Buddhism and Taoism,the quantity of incense burning is increasing.In order to decrease the cost,a large mount of poor quality incense is manufactured and flows into the temples.In this paper,in order to investigate the air pollution due to incense burning in mainland China,the airborne concentrations of inhaled particles(PM10) and formaldehyde concentration were measured at different test sites in two temples located in Beijing.The results indicated th...
