| 摘 要： | 采用致突变和抗突变同步快速试验对石家庄市１９９３年５个大气检测点的空气悬浮颗粒标本进行检测。发现石家庄市空气悬浮颗粒存在直接和间接致突变作用，未发现抗突变作用。致突变阳性率有季节性差异并按冬春夏秋顺序呈递减趋势。致突变阳性率与其颗粒（ＴＳＰ）、二氧化硫（ＳＯ２）的浓度呈正相关。与臭氧（Ｏ３）浓度呈负相关；与氮氧化物（ＮＯｘ）、一氧化碳（ＣＯ）的浓度无关。 |

| Abstract: | amples of airborne suspended particles collected from five air monitoring sites in Shijiazhuang City in 1993 were analyzed with rapid synchrondus mutagenicity and anti-mutagenicity tests,It revealed air-borne suspended particles collected had direct and indirect mutagenicty,but no anti-mutagenicity,and there was seasonal difference in their mutagenicity,which showed a decreasing trend with an order of winter,spring,summer and autumn,Mutagenicity related positively to air concentrations of total sus-pended particles and sulfur dioxide,inversely to those of ozone,and did not related to those of nitrogen oxide and carbon monoxide. |
