FIELD: chemistry.
SUBSTANCE: method involves homogenisation and dehydration of a sample, extraction, purification of the extract from lipids by a sorbent modified by sodium hydroxide, elution of polycyclic aromatic hydrocarbons and identification thereof with quantitative determination, wherein extraction is carried out with acetonitrile, purification of the extract from lipids is carried out in static conditions for not less than 8 hours on a sorbent which is modified with sodium hydroxide, where the sorbent used is aluminium oxide, and elution of the polycyclic aromatic hydrocarbons is carried out with 5-10 ml acetonitrile.
EFFECT: high accuracy and simple analysis.
