| 摘 要： | 利用紫露草微核技术对大气中重要的污染物ＳＯ２和ＮＯｘ进行了室内外试验。结果表明，紫露草对大气中ＳＯ２和ＮＯｘ较敏感，紫露草微核频率ＭＣＮ％（效应ｙ）与ＳＯ２、ＮＯｘ的浓度（剂量ｘ）的关系在一定的范围内呈正相关。对于ＳＯ２当浓度在０．００－３．７５ｍｇ／ｍ＾３之间时，对应的微核频率ｙ＝８．３８＋４．３８ｘ，ｒ＝０．９１；对于ＮＯｘ当浓度在０．００－１．００ｍｇ／ｍ＾３之间时，对应的微核频率ｙ＝４．８

| Abstract: | study has been carried out on monitorinsatmospheric SO2 and NO. by using Tmicronucleus technique. The results showed thatTradescantia was sensitive to a variation in theatmospheric concentration of SO2 and NOx. ATradescantia micronucleus response (frequency) wasclosely related to the domain doses (concentrations)of SO2 and NOx in the air. A linear regression equation of the Tradescantia micronucleus frequencyas a function of SO2 and NO. doses had beendeduced. It was found that the response to SO2 wasinferior and opposite to a response to NOx. This canbe used to properly estimate the concentrations ofSO2 and NOx in the air and to assess the level of airpollution. |
