“…Studies have shown that plant roots can absorb PAHs and transport LPAHs to the surface, and that HPAHs can attach to roots [49]. Leaves and other plant tissues can absorb atmospheric PAHs [50], which can be deposited into the surface soil via rainwater and deciduous leaves [51]. Therefore, plant–PAH interactions could contribute to the shallower distribution of PAH.…”

Polycyclic aromatic hydrocarbons (PAHs) are highly teratogenic, persistent carcinogens, and ubiquitous environmental pollutants. To determine the impact of rapid urbanization on sediment/soil PAHs, we collected 30 cm soil cores in ditch wetlands, riverine wetlands, and agricultural lands along the lower reaches of the Shiwuli River feeding Chaohu Lake, China. Ecological risk effects were evaluated by two models based upon Benzo[a]pyrene toxic equivalency (TEQ-BaP) and total toxic units (TUs). The presence of PAHs, such as BbF, BkF, InP, and BgP, that are known pollutants of concern, suggests certain ecological risks. The concentration of PAHs in the surface layer followed in the order of: ditch wetlands (617.2 ng/g average), riverine wetlands (282.1 ng/g average), agricultural lands (103.7 ng/g average). PAHs in ditch sediments were vertically distributed evenly, and PAHs in agricultural soils were concentrated in the surface soil. In riverine wetland sediments, the 2-, 3-, and 4-ring PAHs had a uniform distribution, whereas the 5- and 6-ring PAHs were concentrated in the surface soil. Redundancy analysis (RDA) explored the correlation between the environmental properties and the occurrence of PAHs. Total organic carbon (p = 0.010), percent clay (p = 0.020), and distance (p = 0.020) were the primary factors in ditch wetlands. Depth (p = 0.010) and distance (p = 0.006) were the main factors in agricultural lands. There were no significant correlations in riverine wetlands. The correlation between the distance from the built-up urban areas and pollutant concentration showed that the closer the distance, the greater the concentration of PAHs.

“…While ash leaching is affected by a variety of aspects upon application to forest soils, e.g. redox conditions, interaction with the soil organic matter, sorption, transport, repartitioning, mineralisation and revolatilisation of organic compounds (for more details on the mobility of inorganic compounds into the soil refer to Carter et al (2009) and Fang et al (2017), whereas for the organic compounds refer to Aichner et al (2015), Komprdová et al (2016) and Obrist et al (2015)), the above estimations nevertheless offer general insights into the source-term release of nutrients and contaminants onto soil.…”

In Denmark, increasing amounts of wood ashes are generated from biomass combustion for energy production. The utilisation of ashes on top of forest soil for liming purposes has been proposed asan alternative to landfilling. Danish wood ash samples were collected and characterised with respect to chemical composition, mineralogy and leaching properties (batch leaching at L/S 2 and 10L/kg, and pH-dependent leaching at 10L/kg). Large variations in the ash liming properties were observed (ANC: 1.8-6.4meqH/g), indicating that similar soil application dosages may result in different liming effects. High contents of Ca, Si, P, K and Mg were observed in all samples, while the highest contents of S and N were found in fly ashes and mixed ashes (combination of fly and bottom ashes). Similarly, the highest contents of some trace metals, e.g. Cd, Mo and Se, were observed for fly ash. Releases of major, minor and trace elements were affected significantly by pH: high releases of PO, Mg, Zn, Cu and Cd were found for acidic conditions relevant to forest soils, while the highest releases of Mo and Cr were observed in alkaline conditions. Mineral phases were selected based on XRD analyses and the existing literature, and they were applied as inputs for the geochemical modelling of pH-dependent leaching. Mineral dissolution was found adequate for a wide range of major elements and nutrients, while the description of trace elements could be done only for parts of the pH-range. Content and leaching of PAHs were observed below detection limits. The source-term release of Ca, K, Mg, Mn, and P in acidic conditions relevant to forest soils was higher than ten years of atmospheric deposition, in contrast to the relatively low release of Al, Fe and Na. The potential release of Cd was found to be the most critical element compared with soil quality criteria, whereas the maximum theoretical loads of Ba, Cd, Cr, Sr, Mo, Ni, Pb, Sb, Se, Sn and V were relatively low.

“…Tree species affect pH and cation-exchange capacity (CEC) of soil (Mueller et al 2012;Gałka et al 2014;Gruba and Mulder 2015). Species composition of trees affects the quantity and quality of soil organic matter (SOM) (Augusto et al 2002;Hobbie et al 2007) on which the accumulation of heavy metals (Biernacka and Małuszyńska 2006) and PAHs (Komprdová et al 2016) depends. Heavy metals bound on insoluble humic substances are relatively immobile (Borůvka and Drábek 2004).…”

Assessment of forest soil contamination in Krakow surroundings in relation to the type of stand

The aim of the study was to determine the degree of soil pollution in different forest types around Krakow, using biochemical, chemical and magnetic methods. In assessing the degree of soil contamination, the impact of the forest species composition by comparing the surfaces of broadleaf and coniferous forest stands was taken into account. Enzymatic activity was related to other measures of pollution, i.e., heavy metal concentration, content of polycyclic aromatic hydrocarbons and level of magnetic susceptibility. The study was conducted in southern Poland. Krakow was the central point around which the test surfaces were designated. In soil samples pH, soil texture and organic carbon, nitrogen, base cation contents, dehydrogenase and urease activities were determined. Additionally, heavy metal concentration, polycyclic aromatic hydrocarbons (PAHs) content and magnetic susceptibility were recorded. The obtained results confirm the high diversity of forest soil pollution around Krakow agglomeration. Significant differences in both the content of heavy metals, polycyclic aromatic hydrocarbons and values of the magnetic susceptibility were observed in the soils of forest complexes located in different directions away from Krakow and at various distances from Krakow. The level of contamination is related to the historical and current deposition of industrial and urban dusts from Krakow and Silesia. The type of stand had a considerable influence on the content of polycyclic aromatic hydrocarbons. A higher content of aromatic hydrocarbons was observed in the soils of deciduous stands. A high level of magnetic susceptibility was observed in the soils of coniferous stands. The differences in enzymatic activity between the research plots result from different contents of PAHs and different amount of soil organic matter resulting from the species composition.
