Ratio method is mainly a lied in qualitative a ortionment. Com rehensive source finger rints are required for chemical mass balance method , while more data are required for multivariate statistical analysis method. Broad a lication of chemical mass balance method is hindered by the absence of a reliable combustion source finger rints and the reactivit y and instability of PAHs, w hile com rehensive source finger rints aren. t required and decay of PAHs can not be considered for multivariate statistical analysis method. Therefore multivariate statistical analysis method is of high value of a lication.
