Keywords fungal to bacterial ratio, microbial activity, microbial biomass, microbial community structure, phospholipid fatty acid, physiological stress ratio. Summary Profiling of microbial communities in environmental samples often utilizes phospholipid fatty acid (PLFA) analysis. This method has been used for more than 35 years and is still popular as a means to characterize microbial communities in a diverse range of environmental matrices. This review examines the various recent applications of PLFA analysis in environmental studies with specific reference to the interpretation of the PLFA results. It is evident that interpretations of PLFA results do not always correlate between different investigations. These discrepancies in interpretation and their subsequent applications to environmental studies are discussed. However, in spite of limitations to the manner in which PLFA data are applied, the approach remains one with great potential for improving our understanding of the relationship between microbial populations and the environment. This review highlights the caveats and provides suggestions towards the practicable application of PLFA data interpretation.

“…Sediment PAH concentrations decreased from north to south in the China Sea because of high PAH emissions in North China (Y. Li & Duan, 2015). The average sediment PAH concentration in the Bohai Sea was lower than those observed along the western seacoast of South Korea (Cho et al, 2009), the Persian Gulf (Sinaei & Mashinchian, 2014), the Klang Strait in Malaysia (Tavakoly Sany et al, 2014), San Francisco Bay (Nilsen et al, 2015), the Mediterranean coast of Egypt (Barakat et al, 2011), and the Mediterranean Sea in Italy (Cannarsa et al, 2014). The PAH concentrations were similar to those measured in the East China Sea (Q. Wang et al, 2019), the Northern Adriatic Sea in Italy (Acquavita et al, 2014), and the Gulf of Suez (Nemr et al, 2005).…”

The distribution, risks, and sources of polycyclic aromatic hydrocarbons (PAHs) observed in seawater and sediments in the Bohai Sea were reviewed. The ecological risk of total PAHs in seawater was low, but the ecological risks of several individual PAHs (Pyr, BbF, and IcdP) were high. Detected PAHs in sediments rarely had adverse biological effects. High PAH concentrations were identified in Bohai Bay, in the sea area near Qinhuangdao, in Jinzhou Bay, and in Bohai Strait. Low PAH concentrations were found in the central Bohai, in Laizhou Bay, and in the sea area with more intensive ocean currents near Caofeidian. PAH concentrations in the Bohai Sea present a seaward-decreasing trend. Their spatial distribution could be attributed to the influence of human activities (population, industrial activities, and shipping activities), which determined PAH emissions. The PAHs were characterized by local sources, indicating that coal consumption and vehicle emissions were important sources of PAHs.
