In contrast,
beef burgers and sausages cooked at 7 cm above briquettes
contained similar amounts of PAH. PAHs in sausages and other food
types cooked 4 cm from briquettes all contained similar concentrations
of PAH8, but at a cooking distance of 7 cm, sausages had
about 3-fold higher PAH concentrations than the other food types.
This difference may be at least partly attributable to the way in which
briquettes absorb fat that drips from the cooking food, resulting in
pyrolysis and PAH formation
