英文摘要	In order to evaluate the toxicity of PM2.5 in the Dushanzi area, PM2.5 samples were collected from December 2015 to July 2016, and a plasmid DNA damage assessment method was used to analyze the variation in the oxidative damage ability and its relationship with sampling conditions and toxic components (polycyclic aromatic hydrocarbons, and heavy metals) loaded on the surface of PM2.5. The results showed that the TD30 values (toxic dosage of PM2.5 causing 30% of plasmid DNA damage) of both the whole samples and the water-soluble fractions were lower during the heating period (369 mu g/mL and 536 mu g/mL, respectively), but higher in the dust period and non-heating period (681 mu g/mL and 498 mu g/mL, respectively; and 804 mu g/mL and 847 mu g/mL, respectively). Studies on the effect of meteorological parameters showed an increasing trend in TD30 values for the whole samples and the water-soluble fractions as relative humidity, temperature and wind speed decrease. TD30 values for the whole samples and the water-soluble fractions were negatively correlated with Flu (r = -0.690,r = -0.668; p < 0.05), Flt (r =-0.671, r = -0.760; p < 0.05), BaP (r = -0.672, r = -0.725; p < 0.05), IcdP (r = -0.694, r = -0.740; p < 0.05), Pyr (r = -0.727, r = -0.768; p < 0.01) and BghiP (r = -0.874, r = -0.845; p < 0.01) during the heating period, while As (r = 0.792, r = 0.749; p < 0.05) and Sr (r = 0.776, r = 0.754; p < 0.05) during the dust period showed significant positive correlation. In addition, the TD30 values of PM2.5 collected during sand blowing weather was the highest (1458 mu g/mL and 1750 mu g/mL), while the average TD30 value of PM2.5 collected on hazy days were the lowest (419.8 mu g/mL and 488.6 mu g/mL). Particles collected on the first day after snowfall showed a lower oxidizing capacity (676 mu g/mL and 1330 mu g/mL). The characteristic TD30 values combined with back trajectory analysis indicated that hazy days were heavily influenced by air masses originating from the southern continent and local emissions, whereas the sand blowing weather came from the north of the Taklimakan Desert.
