Additionally, the results of different studies were reported for a
single or few detected PAHs viz. P4 PAHs, P8 PAHs, P13 PAHs or
P16 PAHs making it difficult to normalize and address suitable toxicological
evaluations. Though European Food Safety Authority
identified P8 PAHs or P4 PAHs as good toxicity indicators, but
reports on food PAHs levels show that these indicators solely fail
to give overall view of the exposure and also stated them as not
sufficient indicators to establish dietary exposure of PAHs.
