Abstract
Determination of xenobiotics in samples of
airport runoff water is both a complex and indispensable
task due to an increasing threat resulting from the activities
of numerous airports. The aim of this study was to develop,
optimize, and validate a procedure based on liquid–liquid
extraction (LLE) coupled with gas chromatography–mass
spectrometry (GC–MS) for the determination of polycyclic
aromatic hydrocarbons (PAHs). So far, no procedure was
available that would ensure reliable data about concentration
levels of these toxic pollutants in a new type of
environmental samples, such as airport stormwater. The
most difficult step in the analytical procedure used for the
determination of fuel combustion products in airport
stormwater samples is sample preparation. In this work,
eight different protocols of sample preparation were tested.
The evaluation of the LLE demonstrated that the best
extraction conditions were as follows: dichloromethane
(extraction solvent), solvent volume of 15 mL and sample
volume of 250 mL. The percent recovery values ranged
from 66 to 106 %, which shows that the LLE technique is a
powerful method for extracting PAHs from airport runoff
water samples with a complex matrix composition. Moreover,
the developed procedure was characterized by
satisfactory selectivity and a relatively low LOQ
(0.17–0.52 µg/L). The procedure has been successfully
applied to the analysis of stormwater samples collected
from different sites at international airport in Poland. The
procedure can thus be used as a tool for tracking the
environmental fate of these compounds and for assessing
the environmental effect of airports.
