摘要
本文用GC/MS测定了蒸汽机车锅炉烟囱内侧附壁烟灰中致癌性多环芳烃,共鉴定出12种致癌性多环芳烃,含量为102.88μg/g,其中强致癌性多环芳烃有五种,含量为56.84μg/g,弱致癌性芳烃七种,含量为46.04μg/g。
The analysis of carcinogenic polycyclic aromatic hydrocarbons (PAHs) in sample of smoke ash by GC/MS are described in this paper. The sample was collected from the chimney of steam locomotive. 12 carcinogenic PAHs are identified. The total concentration of 12 PAHs is 102.88μg/g. Among the 12 PAHs there are 5 strong carcinogens and 7 weak carcinogens. The total concentration of 5 strong carcinogens is 56.84μg/g and 6 weak carcinogens is 46.04μg/g.
