为公共场所空气可吸入颗粒物监测选择比较适用的方法并为制订国家公共场所空气可吸入颗粒物卫生检验标准方法提供依据，分别用P-5L2型光散射测尘仪、LD-1型激光粉尘仪和滤膜称重法同时对常州地区4类公共场所分春、夏、秋、冬4个季节进行监测。结果表明质量浓度与相对浓度存在明显相关(r1=0.7787，P＜0.001；r2=0.7526，P＜0.001)，相对浓度和质量浓度的转换系数(K)呈近似正态分布，P-5L2型光散射测尘仪与LD-1型激光粉尘仪的K的均值分别为0.0163、7.42×10-4，K值均不随公共场所行业类型、季节以及是否使用空调而改变，监测结果稳定。表明采用光散射法替代滤膜称重法是可行的，P-5L型光散射测尘仪、LD-1型激光粉尘仪在公共场所空气可吸入颗粒物监测中具有较大的适用性，鉴于地区间K值存在差异，故仪器使用前宜测定当地的K值。

In order to select a better fit method for the monitoring tho- racic particles in air of public place and supply proofs for the estab- lishment of national standard method for hygienic examination of thoracic particles in air of public place. P-5L2 light scattering dust analyser, LD - 1 laser dust monitor and filterpaper weight method were used to monitor thoracic particles at the same time in spring, summer, autumn and winter in four types of public places of Chang zhou area. The results showed that quality ocncerntration and rela- tive coneerntration have significant correlation ( r1 = 0. 7787, P ＜ 0.001; r2 = 0. 7526, P ＜ 0.001 ), and the conversion coefficient (K) of relative concentration andquaity concentration was demon- strated approximate normal distribution. The average coefficient of P - 5L2 light scattering dust analyser and LD - 1 laser dust moni- tor were 0. 0163, 7.42 × 10-4 respectively. The conversion coeffi- cient did not vary with type of public place, season and whether using air conditioner or not. The monitoring results were stable. So it is feasible to apply light scattering method instead of filterpaper weight method. And P - 5L2 light scattering analyser and LD - 1 laser dust monitor have much compatibility in monitoring thoracic particles in public place. In view of differences of convers coeffi- cient among different areas. Therefore, the conversion coefficient should be measured before using the apparatus.
