实时监测法分析煤烟中的多环芳烃

MONITOR PAHS IN COAL FUME BY REAL-TIME METHOD

[目的]运用实时监测法比较普通煤和固硫煤燃烧产生的煤烟中多环芳烃含量差异,初步研究实时监测法分析多环芳烃的优点以及固硫型煤对人体健康的影响。[方法]随机选择一户以煤为燃料的农村家庭,使用E-COCHEM的PAS2000CE连续实时监测其燃烧固硫煤和普通煤时周围环境中多环芳烃的含量。[结果]空气中多环芳烃含量为普通煤高于固硫煤,在灶台处最高,厨房和室外次之。[结论]煤烟中多环芳烃的主要作用对象是长期从事烹调活动的家庭妇女,使用固硫型煤对人体健康的危害较使用普通煤小。运用实时监测法可动态连续地研究周围环境中的多环芳烃。

[Objective] To compare the different content of polycyclic aromatic hydrocarbons （PAHs） between raw coal and briquette combustion through real-time monitor, study the advantage of real-time method and briquette＇s influence to people＇s health. [Methods] A rural family which used the raw coal as its fuel was randomly chosen and ECOCHEM PAS200OCE was used to monitor its content of PAHs when raw coal and briquette combustion. [ Results] The PAHs of using row coal was higher than that of using briquette. It had the highest PAHs content on stove among the three sample sites, in kitchen and outdoor were lower. [Conclusions] Using briquette as fuel is less harmful than using raw coal for people＇s health. Housewives, who do house cooking, are the main effect objects of PAHs in coal fume. Real-time method can continuously monitor PAHs in environment.
