abstract = "Soil is recognized as an excellent sink for polycyclic aromatic hydrocarbons (PAHs).
At forest stands, this effect is enhanced by the canopy scavenging of trees, which increases
pollutant fluxes from air to soil, e.g. by litter fall. Soil samples of 37 mountain
beech forests from 11 European countries (Bosnia and Herzegovina, Bulgaria, Czech
Republic, Germany, Italy, Poland, Romania, Serbia, Slovakia, Slovenia and Spain) were
analysed for concentrations of polycyclic aromatic hydrocarbons (PAHs) in two sampling
depths (0 - 40, 40 – 80 cm). A Quick, Easy, Cheap, Effective, Rugged and Safe
(QuEChERS) method was applied forthe simultaneous analysis of 16 PAHs (Kim et al.,
2019). High-performance liquid chromatography with diode array detector (HPLC–
DAD) analyses of PAH-containing extracts were carried out on an Agilent 1100 Series
chromatograph.
This study’s main objectives were (i) to study the PAHs occurrence in mountain forest
soils across Europe, and (ii) to decipher the processes behind potential variability in
depth distribution, considering both PAH fingerprints and concentrations.
The total concentrations of Σ16 PAHs in the surface layer (0–40 cm) and sublayer
soils (40–80 cm) ranged from 271.52 - 1154.52 and 318.95 - 1052.54 μg/kg, with
a median of 580.79 and 604.53μg/kg, respectively. There is no statistically significant
difference between groups. The 4-ring and 5-ring PAHs were the most prominent components
in all samples. The concentration of Σ16 EPA PAHs did not exceed the precautionary values set by the soil quality guidelines.",
