摘　　要：本文用ＳＯＳ显色法研究了广州大气总悬浮颗粒（ＴＳＰ）的二氯甲烷（ＤＣＭ）提取物的ＳＯＳ反应诱导力（ＳＯＳＩＰ）。结果表明：不同季度、不同月份的提取物诱导大肠杆菌ＰＱ３７的ＳＯＳ反应能力有明显差异。样品的诱导力与相应月份的气温、气压、风速、以及ＴＳＰ浓度。SOS chromotest was used to study SOS-inducing potency (SOSIP) of dichloromethane (DCM) extracts of total suspended particulates (TSP) from Guangzhou PRC, in a whole year. All the samples tested induced SOS function in tester strain PQ37 without S9mix SOSIP varied significantly from month to month. SOSIP was correlated with meteorological conditions such as tempersature, pressure and wind speed as well as concentrations of TSP and DCM extracts.
