“…The high concentration of total PAH in OS-PM in comparison with the other manure samples might be due to the air deposition of PAH during its outdoor storage in lagoons (O0 • 12'39.53", N40 • 56'14.03"). Deposition rates of PAH reported in the literature such as 70-670 ng⋅m -2 ⋅d − 1 [31] or 18.8-278 ng⋅m -2 ⋅d − 1 [32] and its storage during months in the lagoons could justify the high concentrations determined in OS-PM.…”

The occurrence and distribution of polycyclic aromatic hydrocarbons (PAH) have been investigated in the products derived from the pyrolysis of pig manure at low temperatures (<550 • C) in a fixed bed reactor. The focus was on the sixteen PAH identified as priority pollutants by the US Environment Protection Agency (EPA). The pyrolysis does not generate a significant additional amount of EPA-PAH to that existing in the original pig manure, under the operational conditions studied (<550 • C). While the total EPA-PAH yield does not indicate a notable dependence on the pyrolysis temperature, the EPA-PAH distribution among the three pig manure pyrolysis products as well as the speciation changed significantly with the temperature. The proportion of heavy PAH species increased as the temperature increased. The initial EPA-PAH in the manure samples plays a significant role in both their concentration and speciation in the biochar. The relationship of the EPA-PAH concentration and speciation in the biochar with those of the raw material was corroborated with a cow manure sample and the biochars obtained from its pyrolysis. For this reason, feedstocks with low EPA-PAH concentrations are recommended in order to obtain biochars with concentrations below the maximum allowed threshold established for their use as a soil enhancer by the International Biochar Initiative (IBI) and in the European Biochar Certificate.

“…Heavy metals are listed among inorganic compounds, whereas, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), active halogens adsorbed on activated carbon, expressed by the AOX index, organic halogen or polychlorinated dibenzodioxins or dibenzofurans (PCDD/PCDF) should be mentioned among organic ones (Fijałkowski et al, 2017, Haddaoui et al, 2016, Qu et l., 2019, Petersen et al, 2003. Polycyclic aromatic hydrocarbons belong to the group of persistent organic pollutants (POPs) and their presence in sewage sludge has been confirmed both in literature sources and former studies of co-authors (Fijałkowski et al, 2017, Haddaoui et al, 2016, Qu et al, 2019, Petersen et al, 2003, Zennegg et al, 2013, Liu et al, 2013, Wlodarczyk-Makuła et al, 2015. It should be highlighted that in most studies the PAHs content in reject water is omitted; thus, the previous co-authors' research considered the presence of polyaromatic hydrocarbons in reject water.…”

In the paper, the results of studies on changes in the concentration of selected polycyclic aromatic hydrocarbons (PAHs) in the reject water coming from aerobic stabilization of sewage sludge process were given. The sewage sludge samples originating from a treatment of municipal wastewater treatment plant and an industrial coking wastewater treatment plant were investigated. A technological study was conducted using a municipal sewage sludge (control sample) and a mixture of municipal and industrial sewage sludge simultaneously. Aerobic stabilization of sewage sludge process was carried out for 21 days. The concentration of PAHs was determined at the beginning of the experiment (day 0) and in seven-day intervals: after 7, 14 and 21 days. The initial concentration of PAHs in the reject water coming from the municipal sewage sludge was over 44 g/dm 3 . Industrial sewage sludge was heavily loaded with polycyclic aromatic hydrocarbons. In a reject water of the mixture of municipal and industrial sludge, the initial content of PAHs reached over 5200 g/dm 3 . During aerobic stabilization of sewage sludge, a decrease in PAHs concentration in reject water was observed. After 21 days of the experiment, the decrease of the sum of analyzed PAHs was in the range of 62-98%.

“…The geochemical mapping provides a more detailed information about the spatial variability of chemical components for environmental studies, particularly in discriminating potential sources of contribution (either anthropogenic and geogenic) in global, continent and regional scale (Albanese et al, 2007;Darnley and Garrett, 1990;Darnley et al, 1995;Gałuszka, 2007;Plant et al, 2001;Qu et al, 2018Qu et al, , 2019Caritat, 2017, 2005;Yuan et al, 2013;Sahoo et al, 2019aSahoo et al, , 2019bSahoo et al, , 2020Salomão et al, 2019). The presences of mineral resources (such as copper, lead, zinc, mercury, gold, silver) and carbonate and basalt parent materials often lead to elevated PTMs in soil (Barsby et al, 2012;Cabral Pinto et al, 2017;Cheng, 2016;Cox et al, 2017;Goldhaber et al, 2009;Tolosana-Delgado and McKinley, 2016;Wang et al, 2015;Zhang et al, 2002).…”
