  • In this paper, ketone and alcohol lipid compounds in airborne particulates from Lanzhou city have been analy sed and studied.The concent rations of n-alkan-2-ones and n-alkanols are 20-270 ng.m-3 and 520-910 ng.m-3, respectively.They have higher concent rations in March than in July and August, which is related to special topog raphy and climate of Lanzhou area.The dist ribution of these compounds indicates that they are derived anthropogenic activity, microbes and modern higher plants and the assignment of their sources is 2.8 %～ 19.7 % fo r anthropogenic acitivity, 15.4 %～ 34.6 % for microbes and 50.3 %～ 81.8 % for modern higher plant s.Sterols are present at low concent rations,which are provided by modern organisms.The presence of abundant C18 isoprenoid ketone shows that org anic mat ter in airborne particulates f rom Lanzhou city is transformed in the oxidizing process of the atmosphre.
