2023, Science of the Total EnvironmentCitation Excerpt :PAH deposition fate in estuaries could be impacted by sedimentary properties such as grain size, total organic carbon (TOC) and deposition rate (Wang et al., 2017, Huang et al., 2021a, 2021b). Therefore, PAHs distributions pattern and their burial fate in estuarine sediments could not only indicate the change in sedimentary environment, but also be regarded as a good indication of anthropogenic impacts (Kanwischer et al., 2020). The Pearl River Estuary (PRE) links the vast Pearl River network and the South China Sea with several outlets and receives material inputs from multiple sources (Hu et al., 2011).
Assessing the chemical anthropocene – Development of the legacy pollution fingerprint in the North Sea during the last century
2022, Environmental PollutionCitation Excerpt :Whereas Boitsov et al. (2013), who sampled the area in 1992–1995, could not detect a decreasing trend for PAHs in most analyzed sediment cores, our study results show a clear decreasing trend for PAHs towards younger sedimented material, which indicates lower recent PAH emissions from anthropogenic sources. Calculated diagnostic ratios between pyrogenic and petrogenic PAHs for source identification (Bigus et al., 2014; Kanwischer et al., 2020; Neff et al., 2005; Pérez-Fernández et al., 2016; Wang et al., 2020) were all stable throughout the sediment core and revealed that PAH most likely originate from sources of mixed pyrogenic origin such as coal, biomass and petroleum combustion. In contrast, concentrations of most methylated PAHs, which originate mainly from petrogenic sources, increase towards the top layers of the sediment core.
