| 摘 要： | 2010年6月6日至6月16日,运用采样器TH-110B和TH-150C收集了地处沿淮麦区3个观测点的气体（NH3和NO2）和气溶胶样品,初步探讨了小麦收获期大气气态氮和颗粒态氮质量浓度的特征。结果表明：气态氮质量浓度以NO2最高,其时均质量浓度和日均质量浓度分别为0.57～0.64 mg.m-3和0.29～0.63 mg·m-3,且均超标（0.24和0.12 mg·m-3）;颗粒态氮质量浓度以NH4＋-N最高（4.12～78.28μg·m-3）,占总氮的47.00%～71.19%。此外,农业活动如收割,可增加大气气溶胶及无机态氮的质量浓度。 |

| Abstract: | Concentrations of atmospheric inorganic nitrogen including gaseous nitrogen(NH3-N and NO2-N) and aerosol nitrogen(NH4+-N and NO3--N) were monitored by a TH-110B portable air sampler and a TH-150C intelligent medium-flow sampler at three winter-wheat growing fields along the Huaihe River during June 6-June 16,2010.The results showed that NO2-N concentration was higher and its hourly and daily concentrations were in the ranges of 0.57-0.64 and 0.29-0.63 mg.m-3,respectively,all of which exceeded the national s... |
