[Studies about the values of polycyclic aromatic hydrocarbons in oils used in production of plant protective agents].

Determination of polycyclic aromatic hydrocarbons (PAH) contents in oils used in agriculture and forestry as additives to plant protection agents was made. PAH were isolated from oil samples by column chromatography, and TLC was applied for their identification and determination. PAH (fluoranthene, perylene, phenanthrene) were present in three oil samples, whereas they were not detected in three subsequent samples. The sensitivity of the method is +/- 0.1 ppm.
