Abstract
The concentrations and profiles of polycyclic aromatic hydrocarbons PAHs were determined in twenty popular commercial brands of milk in the Nigerian market after saponification with ethanolic KOH and cyclohexane extraction and clean up using a gas chromatography with flame ionization detection The concentrations of the Σ16 PAHs in these brands of milk ranged from 156 to 17118 μg kg−1 The dominant PAH compounds in these brands of milk were 3and4rings PAHs The dietary intake of BaP PAH2 PAH4 and PAH8 were 0–539 and 0–3696 ng kg−1 bw day−1 respectively Using these indicators for occurrence and effects BaP PAH2 PAH4 and PAH8 PAHs in food the margin of exposure were 10000 in 15–30 of the brands
