摘要: 应用环境磁学方法对北疆昌吉地区和南疆阿克苏地区大气降尘的磁学特征进行对比研究。结果表明:2012年春夏季昌吉地区大气降尘样品磁性矿物以磁铁矿和磁赤铁矿为主,阿克苏地区样品除受到磁铁矿、磁赤铁矿主要控制外,还含有更多赤铁矿等高矫顽力磁性矿物。两地降尘样品都以假单畴颗粒PSD和多畴颗粒MD为主。昌吉地区大气降尘样品的磁性矿物含量明显高于阿克苏地区。阿克苏地区大气降尘样品以天然降尘为主,强磁性矿物含量较低;昌吉地区降尘样品人为源输入强度高,磁学信号强。大气降尘的磁学特征包含大量环境信息,可以作为粉尘环境监测的重要手段。严格控制工业污染物排放,合理规划工业布局,依旧是治理城市大气污染的重要措施。

Abstract: The magnetic characteristics of the dustfall samples from Changji and Aksu in Xinjiang were analyzed by environment magnetism method.The results indicate that the main magnetic grain sizes in dustfall samples are multidomain(MD) and pseudo-single domain(PSD) from March to August of 2012, while dustfall samples of Aksu contain more hematite. The content of magnetic mineral in dustfall samples from Changji is much higher than that of Aksu. Samples of Changji are dominated by anthropogenically derived particulate matter with strong magnetic signals, but natural dustfall with low magnetic mineral content is the main component of samples in Aksu. The magnetic characteristics of dustfall samples contain a large amount of environmental information and environmental magnetism is an effective measurement in monitoring dust pollution. Controlling urban air pollution must control the industrial pollutions and plan the industral layout reasonable.

Key words: environment magnetism, dustfall, Changji, Aksu
