摘要: 为探究室内地面灰尘中15种多环芳烃(PAHs)污染的时间变化规律，于2012年3—7月对北京市一座办公楼内的某办公室进行了每周一次的连续高密度灰尘样品采集。利用高效液相色谱-荧光检测器检测15种PAHs含量。结果表明，该办公室内灰尘样品中∑PAHs浓度范围为1 180~24 300 ng·g^-1，平均浓度为8 960 ng·g^-1。总体上，检出的PAHs以3环PAHs为主，其中菲占PAHs总量的59%以上，其次是4环和5环PAHs，4环PAHs中䓛占的比重最高，约占4环PAHs总量的34%。该办公室内灰尘中∑PAHs的浓度存在显著的时间变化差异，总体表现为∑PAHs浓度随气温升高而降低的趋势。源解析结果显示，机动车排放源、石油源、木材与煤燃烧是北京市室内灰尘中PAHs的主要来源。健康风险评估结果显示，ILCR_皮肤接触 > ILCR_手口摄入，且CR均值大于10^-6，说明该采样点的PAHs污染存在“潜在致癌风险”。

Abstract: In order to explore the time variation of fifteen polycyclic aromatic hydrocarbons (PAHs) pollution in floor surface dust, dust samples were collected once a week from Mar to July in typical Beijing office in 2012. Fifteen types of PAHs were detected by means of HPLC-FLD (High Performance Liquid Chromatography-Fluorescence Detector). The results showed that ∑PAHs concentrations ranged from 1 180 to 24 300 ng·g^-1, and the average concentration was 8 960 ng·g^-1. In a word, detected PAHs were mainly composed of 3 ring congeners, in which PHE accounted for more than 59% of the total content, followed by the 4-ring and 5-ring congeners, and CHR accounted for the highest proportion (34%) of 4-ring PAHs. Additionally, ∑PAHs concentrations of floor surface dust decreased with the increase of temperature for the investigated office, indicating its significant time course. The results of source apportionment showed that the emission of motor vehicles, petroleum sources, the combustion of wood and coal were the primary sources of PAHs present in floor surface dust. Health risk assessment results indicated that ILCR_{dermal contact} > ILCR_ingestion, and the mean value of CR was higher than 10^-6. In conclusion, PAHs pollution in the sampling site has potential carcinogenic risk to the staffs in the office.
