Assessing of organic content in surface sediments of Suez Gulf, Egypt depending on normal alkanes, terpanes and steranes biological markers indicators

Discriminating source of oil contamination in teleost fish, Lates calcarifer, using multivariate analysis of a suite of physiological and behavioral biomarkers

“…Crude oils are highly complex mixtures of several thousand compounds with chemical biomarker profiles that differ greatly depending on the source. In heavily developed industrial areas, petroleum hydrocarbon pollutants found in the environment may originate from several sources, each with a distinctive chemical fingerprint (Elfadly et al, 2017). Heavy fuel oil (HFO) (also termed bunker oil or heavy diesel oil) refers to blended residual products from the distillation of crude oil commonly used in merchant vessels (Fritt-Rasmussen et al, 2018).…”

Distribution of oil, grease and polycyclic aromatic hydrocarbons in coastal water and sediments of Suez Bay

“…The content of PAHs was assessed in the aquatic ecosystem of the GS region. PAHs were analyzed in the surface sediments and in eleven fish species from the Gulf of Suez (Abdallah et al 2016;El-Agroudy et al 2007;Elfadly et al 2017;Younis et al 2018). Their content ranged from 1667.02 to 2671.27 ng g −1 , with the highest levels observed at the towns of Ras Gharib, Aion Mousa, and Abu Zanima.…”

“…The presence of PAHs and aliphatic hydrocarbons (AHs) in the GS has been attributed to anthropogenic activity, as well as petrogenic and biogenic sources (Abdallah et al 2016). Non-aromatic hydrocarbons in the GS have been reported as originating from multiple terrestrial sources, being of biogenic and pyrolytic origin, and include mainly petrogenic and biogenic hydrocarbons (Elfadly et al 2017). The main sources of petroleum contamination are the port of Al-Attaqa, the Suez oil processing company, the Al-Nasr Oil Company, AL-Kabanon, and EL-Sukhna of Loloha Beach.…”
