%X At petrochemical complex industrial sites in the southwestern suburb of Beijmg，oil has been the major energy source．The air particulate samples were collected separate!y for 3-4 consecutive days every month．The results showed that there are apparent correlations among monthly changes of weight of extracts，their mutagenicities and concentrations of PAHs．The weights for the day-time samples were higher than those for the night-time．Wights of extracts．revertant numbers．BαP concentration etc．were all lower for the petrochemical complex industrial site(PCIS)than for iron-steel complex site(ISCS)．However，mutagenicities per unit weight of extracts were higher for PCIS than for ISCS．
