“…Long chain alkyl benzenes and alkyl toluenes are common constituents of crude oils and sedimentary organic matter (Albaigés et al, 1986;Williams et al, 1988;Radke and Willsch, 1993;Sinninghe Damsté et al, 1993;Hartgers et al, 1994). Homologous series of long chain alkyl benzenes have been reported in a number of different geological samples (e.g.…”

a b s t r a c tPhytanyl benzene and phytanyl toluene occur in mudstones from several key Permian-Triassic Boundary (PTB) sections from mid-northern palaeolatitudes (Spitsbergen and Eastern Greenland), as well as mid-southern palaeolatitudes (Western Australia). The occurrence of these compounds through the different PTB sections is related to the occurrence of the previously identified C 33 n-alkyl cyclohexane, suggesting their parent organism shared a similar unique ecological niche and was associated with the extinction horizon. Further, the lack of these compounds in the carbonate-dominated palaeoequatorial, Global Stratotype Section and Point (GSSP), Meishan-1 (South China) section possibly points to their source being temperature and climate controlled.

“…Although long-side-chain alkylbenzenes are present in most crude oils, only occasionally have they been identified. The occurrence of the homologous series of n-alkylbenzenes, methyl-n-alkylbenzenes (n-alkyltoluenes) and dimethyl-n-alkylbenzenes (n-alkylxylenes) in crude oils, sediments or kerogens has been documented (Solli et al 1980;Ostroukhov et al 1983;Albaiges et al 1986;Philp & Gilbert 1986;Sinninghe Damste et al 1988Williams et al 1988;Ellis et al 1992Ellis et al , 1995Dong et al 1993;Radke & Willsch 1993). In addition to long-side-chain n-alkyl substituents, a number of alkylbenzenes with isoprenoid side chain have also been detected in oils and sediments (Schaefle et al 1977;Ostroukhov et al 1982;Summons and Powell 1987;Sinninghe Damste et al 1988;Xinke et al 1990).…”

Long-side-chain alkyl compounds, such as those present in oil and oil products, either of natural or of anthropogenic origin or released by industrial activities, are a ubiquitous group of chemicals in the environment. Among them, long-side-chain alkylmonocycloalkanes, alkylbenzenes, and alkyl organic sulfur compounds are largely found in fossil fuels while long-side-chain alkylbenzene sulfonates and alkylphenols are released into the environment primarily due to domestic activities. The present article briefly summarizes the advances that have occurred in this field in terms of the identity, abundance, possible origin and significance of these long-side-chain alkyl compounds found in the environment. In addition, the susceptibility to biodegradation and the fate of these chemicals in the environment are discussed.

“…5 -By6) and the high contents of alkylbenzenes and alkylmethylbenzenes (Nádudvari et al, 2020a). According to Radke and Willsch (1993), large quantities of n-alkanes (n-C15-C26), long-chain alkylbenzenes, alkyltoluenes, and benzo [b]thiophenes are produced between 170 and 360°C through the primary cracking of the coal matrix. Also, self-heating hot spots are characterised by high concentrations of emitted gases like H2, CO2, CH4, C₂H, C3H8, C2H4 and with two, three times less O2 content (Fabiańska et al, 2019;Nádudvari et al, 2020a).…”

The self-heating of coal waste dumps is considered as a serious environmental issue, wherever active or inactive coal mining has been present. This issue is introduced from two active coal mining regions from Poland (Upper Silesian Coal Basin) and Ukraine (Donetsk Coal Basin) based on mineralogy, organic petrography and geochemistry, and remote sensing techniques. Thermally affected coal wastes reveal changes recorded by organic and mineral matter. Irregular cracks and fissures appear within and at the edges of organic matter particles, which are oxidised, devolatilised and plasticised. Mineral phases underwent oxidation, dehydration, structure rebuilding and recrystallisation. Highest temperatures generated during the fire cause melting and paralava formation. During self-heating, some chalcophile elements like Hg (mostly present as HgS), Pb, Zn can be enriched and released, or different organic pollutants like phenols (originated from vitrinite particles), different PAHs with alkyl substitutes, chlorinated PAHs, or sulphur heterocycles are formed. The introduced remote sensing techniques helped to localise and monitor hot spots with different temperature ranges. Applying SWIR bands of Landsat hot spots from extremely burning dumps in Ukraine were successfully localised, however, only night-time scenes with SWIR can be used. The sun’s disturbing effects should be considered as an influential factor for both thermal imaging camera or satellite images. Thermal cameras can reveal the most detailed signs of low to high temperature anomalies with different cracks and line shapes.
