本文用串级冲击式大流量采样器在四个以不同煤种为燃料的氟病区居民室内采集了空气分级颗粒物样品,用 KC-8301可吸入颗粒物采样器采集了上述现场空气中气态和气溶胶态氟化物,同时用离子色谱和离子选择电极等手段对其进行了测定,在此基础上,对各病区室内空气颗粒物及其上主要无机阴离子的浓度、粒度分布规律,空气中不同状态氟的含量等问题进行了初步的探讨,并结合呼吸道沉积理论讨论了它们与人体健康的关系。
In this paper, cascade impact mass flow sampler was used to collect air-grained particulate matter in four indoor residents living in fluoride-wasting areas with different coal types. The airborne particulate matter samples were collected with KC-8301 respirable particulate sampler. The gas and aerosol State fluoride, ion chromatography and ion-selective electrode at the same time and other means to measure it, on this basis, the indoor air particulate matter in each ward and its main inorganic anion concentration, particle size distribution, different states of the air fluoride Content and other issues were initially discussed, combined with respiratory deposition theory to discuss their relationship with human health.
