Highest level was observed in crackers (880 lg/kg)
followed by shortcakes (645.3 lg/kg) while less PAHs were found
in cabin (241.6 lg/kg). The amount of pyrene, fluoranthene and
phenanthrene increased as baking temperature moved above
220 C. Rise in pyrene, benzo(a)anthracene and chrysene levels
was observed at temperature near 260 C which may be due to
transformation of light PAHs and other determining factors like
raw materials used, fuel type, variations in oven temperature and
baking method.
