Determination of polycyclic aromatic hydrocarbons in soil and bottom sediment samples
- Ministry of Public Health, Leningradskaya Oblast (Russian Federation)
Polycyclic aromatic hydrocarbons (PAHs) are environmental pollutants possessing carcinogenic and mutagenic activity. The development and optimization of methods for their determination in various substances remain topical problems. Because of their low water solubility and high boiling points, PAHs accumulate in soil and bottom sediments. Aerosol dust particles can transfer these compounds over considerable distances. Benz[a]pyrene is used as an indicator of PAHs in aerosol particles, soil, water, and sediments, although the PAH composition can vary quite significantly, depending on the sample. The necessity of monitoring the PAH concentration at very low levels imposes rather strict requirements upon all of the stages of the analytical procedure in use. In this work the authors studied the possibility of using column extraction of PAHs from solid matrices with organic solvents, followed by the fractionation of obtained extracts on a column with XAD-2 in the manner described for aqueous samples.
