2.5. PAH profiles or relative abundance ratio of individual PAH
compounds, relative to BaP
PAH profiles or relative abundance ratios of individual PAH
compounds relative to BaP help to assess whether sufficient similarity
exists of the indoor and outdoor air PAH mixtures measured in this
study. The PAH profile (i.e. relative abundance ratio) was calculated as
the ratio of the individual PAHs to the carcinogenic marker BaP
(Eq. (1)), considering only the high molecular weight PAHs, as these
were mainly found in the particulate phase, and carry most of the
carcinogenic potential.
