Regionalized concentrations and fingerprints of polycyclic aromatic hydrocarbons (PAHs) in German forest soils

Microbial Community Dynamics in Field-Scale Biopile Bioremediation

“…Aromatic hydrocarbons analysis revealed very high concentrations at the start of this study compared with other reports [4,26,27] At the end of the monitoring, the pollutant content of the biopile matrix had between 92-98% removal of monoaromatics hydrocarbons and between 57-75% removal of polyaromatic hydrocarbons [2]. On the other hand, heavy metals persist, lead concentration did not register any significant modification, and cadmium, copper, and zinc concentrations were reduced only by 9-16% from initial levels.…”

“…An independent private laboratory analyzed total aromatic hydrocarbons by SR-ISO 7877 [14], BTEX by SR-ISO 11423 [15], and polyaromatic hydrocarbons by SR-ISO 13877 [16] in order to determine soil quality [4]. The parameters of the ASE300 were set according to [11].…”

Occurrence and Spatial Distribution of Selected Organic Substances in Germany’s Forest Soils

“…Thus, their occurrence was due to various sources such as traffic or industrial exhaust fumes. Aichner et al (2013Aichner et al ( , 2015 investigated in their studies with the same data as in the present study the PAH congeners. Based on a study of Khalili et al (1995), they used the two-and three-ring PAHs as indicator for coal-borne sources.…”

Sustainable Use and Development of Forests and Forest Soils: A Resume

“…For PAHs and PCBs, lower concentrations than the precautionary values of the German soil protection legislation (BBodSchV) were found. Densely industrialized and urbanized regions show comparatively enhanced PAHs and PCBs values, e.g., in vicinity of brown-coal strip-mining areas (Aichner et al 2015;Pandelova et al 2018). The long persistence of POPs in forest soils can be seen for DDx applied as pesticide in the 1980s and still detected in the organic layer, particularly in the Eastern Federal States.…”
