“…Studies have reported identification of ninety seven oxygenated PAHs from a municipal waste incinerator [22] and over forty ketone OPAHs were tentatively identified from wood smoke, coal, and diesel combustion [23]. Diesel exhaust could be a significant source of OPAHs, but limited characterization in this media has been done [21, 24-27].…”

Polycyclic aromatic hydrocarbons (PAHs) substituted with a ketone or quinone functionality (OPAHs) may be important environmental contaminants. The OPAHs from environmental samples have demonstrated toxicity and may be more harmful than PAHs. Knowledge gaps concerning the occurrence of OPAHs in the total environment arise from analytical difficulties, as well as limited standards and methodologies. An optimized method was developed to quantify five ketone and four quinone OPAHs from matrices ranging from biological tissue to diesel particulates. Five National Institute of Standards and Technology Standard Reference Materials (SRMs) were analyzed. This is the first report of OPAH quantitation in SRM 2977 (mussel tissue), SRM 1944 (New York /New Jersey, USA waterway sediment), SRM 1975 (diesel extract) and SRM 1650b (diesel particulate matter) and among the few to report concentrations from SRM 1649 (urban dust). Furthermore, this is one of the first reports of OPAHs in biological tissue. Σ9OPAHs were 374 ± 59 μg/kg (mussel tissue), 5.4 ± 0.5 mg/kg (sediment), 16.9 ± 1.6 mg/kg (urban dust), 33.4 ± 0.4 mg/kg (diesel extract), and 150 ± 43 mg/kg (diesel particulate matter). In all SRMs, the levels of OPAHs were similar to or exceeded levels of PAHs. Of the OPAHs tested, the most frequently occurring in the environmental matrices were 9-fluorenone, 9,10-anthraquinone, benzofluorenone, and 7,12-benz[a]anthracenequinone.

“…The presence of OPAHs in the environment is widespread with significant levels found in diesel and gasoline exhaust [148][149][150], emission of gases from combustion processes [151], fly ash [152], urban aerosols [18,19,150,151,153] sediments [154,155], river and coastal waters [156], sewage sludge [157], industrial waste [158], and soil [159][160][161][162][163]. The concentration of atmospheric OPAHs might be higher because PAHs in the atmosphere are more susceptible to photochemical transformation than PAHs in the soil [155].…”

“…Seemingly, multiring aromatic hydrocarbons are contained in soot (i.e., PAHs), 64 but at this time they are seldom treated as the most important carbon source for de novo synthesis. 65,66 Nevertheless, there are many publications showing that multiring aromatic hydrocarbons are emitted in flue gases from incineration power plants 67,68 in relatively high concentrations (even by 3 times more than dioxins and furans) and may constitute a relevant element in the chain of de novo synthesis. 69 The emission of dioxins from the process of clean wood combustion suggests that large, complex molecules of organic compounds such as lignite or brown coal may also be the source of carbon.…”

The first reports that it is possible to emit dioxins from the heat and power generation sector are from the beginning of the 1980s. Detailed research proved that the emission of dioxins might occur during combustion of hard coal, brown coal, and furnace oil as well as coke-oven gas. The emission of dioxins occurs in wood incineration; wood that is clean and understood as biomass; or, in particular, wood waste (polluted). This paper thoroughly discusses the mechanism of dioxin formation in thermal processes, first and foremost in combustion processes. The parameters influencing the quantity of dioxins formed and the dependence of their quantity on the conditions of combustion are highlighted. Furthermore, the methods of reducing dioxin emissions from combustion processes (primary and secondary) are discussed. The most efficacious methods that may find application in the heat and power generation sector are proposed; this is relevant from the point of view of the implementation of the Stockholm Convention resolutions in Poland with regard to persistent organic pollutants.
