| 摘 要： | 采用因子分析及多元线性回归对杭州市室内外空气中PAHs的来源及其贡献率进行研究,求得PAHs总量与公共因子间的特征方程.结果表明,影响室内外空气中PAHs浓度的主要因子依次为烹调、卫生球的挥发、吸烟及加热、汽车尾气.在吸烟者家庭中,室内吸烟是影响室内空气中PAHs浓度的最重要的影响因子,其对室内空气中苯并(a)芘BaP的贡献率为25.8%.

| Abstract: | Twelve polycyclic aromatic hydrocarbons (PAHs) were measured in eight homes in Hangzhou during the summer and autumn in 1999. The sources of PAHs and the contributions of the sources to the total concentration of PAHs in the indoor air were identified by the combination of correlation analysis, factor analysis and multiple regression, and the equations between the concentrations of PAHs in indoor and outdoor air and factors were got. It was indicated that the factors of PAHs in the indoor air were domestic cuisine, the volatility of the mothball, cigarette smoke and heating, the waste gas from vehicles. In the smokers' home, cigarette smoke was the most important factor, and it contributed 25.8% of BaP to the indoor air of smokers' home. |
