Abstract: In order to identify the day and night pollution sources of PM10 in ambient air in Longyan City, the authors analyzed the elemental composition of respirable particulate matters in the day and night ambient air samples and various pollution sources which were collected in January 2010 in Longyan with inductivity coupled plasma-mass spectrometry(ICP-MS). Then chemical mass balance(CMB) model and factor analysis(FA) method were applied to comparatively study the inorganic components in the sources and receptor samples. The results of factor analysis show that the major sources were road dust, waste incineration and mixed sources which contained automobile exhaust, soil dust/secondary dust and coal dust during the daytime in Longyan City, China. There are two major sources of pollution which are soil dust and mixture sources of automobile exhaust and secondary dust during the night in Longyan. The results of CMB show that the major sources are secondary dust, automobile exhaust and road dust during the daytime in Longyan. The major sources are secondary dust, soil dust and automobile exhaust during the night in Longyan. The results of the two methods are similar to each other and the results will guide us to plan to control the PM10 pollution sources in Longyan.
