2022, Marine ChemistryCitation Excerpt :The thermodynamically stable αβ-hopanes and αββ-steranes in two homologue series with R- and S-configurations predominate in crude oils and mature source rock sediments. Therefore, the presence of these compounds in stable configurations in recent sediments indicates petroleum contamination (Yunker et al., 2002; Wang et al., 2011; Yang et al., 2020). The GC/MS hopane (191 m/z) and sterane (218 m/z) composition patterns for all studied sediments were clearly dominated by compounds with configurations typical of petrogenic origin (Fig. 5b, c), which implies prevalent anthropogenic input of these hydrocarbons in the investigated areas.
