“…Warren et al, (2003) suggested that sorption of hydrocarbons takes place directly on sediment surfaces when the organic matter deposition is signi cant. The studies by different researchers (Ruiz-Fernández et al, 2012;Vagge et al, 2018) also support the fact that the silt and clay have signi cant a nity to TOC and hydrocarbons. The accumulation of hydrocarbons is mainly in uenced by the factors such as the type of hydrocarbons and its sources (pyrolytic and / or petrogenic) and most signi cantly the type of sediment (rated by the presence of organic matter) which receives the TPH (Wang et al, 2014).…”

This investigation was made to assess the seasonal accumulation pattern of total petroleum hydrocarbon (TPH) in sediments along the two major ports such as Ennore and Tuticorin, located in Southeast coast of India. The level of TPH was found to vary from 2.05µg g − 1 to 17.47 µg g − 1 . To establish the relationship among the TPH with total organic carbon (TOC) and sediment components, the techniques of correlation analysis and principal component analysis (PCA) were used. The higher accumulation of TPH during monsoon season indicates that all wastes discharged on land was washed and got deposited on the Ennore coast. The signi cant positive correlation with TOC was noticed and the evidences indicated that the sedimentary organic carbon is acting as a strong binding agent for TPH.

“…It is difficult to estimate whether PAHs in surficial sediments of Nova Scotia SCHs are the product of current or historical inputs, as SCHs are routinely dredged. Dredging disturbs sediments and can cause resuspension of contaminants, making it difficult to estimate the impacts of historical and/or current inputs (Shang, Chen, Shen, Wang, & Ruan, ; Vagge et al, ). However, an assessment of surficial sediments in Chesapeake Bay in the US reported dominance of coal‐derived PAHs in surficial sediments, suggesting influence from historical deposition from coal‐related processes, as current coal‐derived PAHs were less dominant in atmospheric and surface water samples (Dickhut et al, ).…”

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in the global environment and are subsequently transported into aquatic sediments. As PAHs are formed by various processes, source identification using diagnostic ratios can provide insight to PAH emission sources to distinguish between pyrogenic and petrogenic PAH sources. PAH diagnostic ratios were applied as a forensic source apportionment technique to assess aggregate historical sediment data from 31 small craft harbors (SCHs) across Nova Scotia, Canada. Multiple diagnostic ratios suggest that PAHs present in Nova Scotia SCH sediments are pyrogenic (combustion) in origin, while consistently suggesting that coal‐related PAH sources are potential dominant specific sources. National Institute of Standards and Technology Standard Reference Materials (SRMs) were used as reference for coal tar, urban dust, and diesel exhaust particulates in ratio applications. The SRM for coal tar was most similar to Nova Scotia SCH sediments in multiple ratio applications. Diagnostic ratio results were corroborated by comparing the PAH profile of sediments to source profiles from the literature. Results indicate that Nova Scotia SCH sediments follow global trends by exhibiting a dominant pyrogenic PAH signature, and the specific coal‐related PAH signature of Nova Scotia SCH sediments may be influenced by contamination inputs related to historical industrial coal mining and combustion activities in the province.

“…Recent studies have reported the occurrence of organic pollutants, such as PAHs, in various aquatic systems such as influent and effluent from wastewater treatment plants, groundwater, surface waters or seawater (Grandclement et al, 2017). Researchers have reported the presence of organic compounds in America (Gilliom, 2007), Africa (Edokpayi et al, 2017), Asia (Lin C et al, 2017), Europe (Wen et al, 2017) and Oceania (Tremblay et al, 2016). In the current study, PAHs, which are toxic to living organisms, were investigated as organic pollutants.…”

“…Adeniji et al (2018) reported that four-ring and five-ring PAHs such as chrysene and benzo[a]pyrene are almost insoluble in water. Because of this characteristic, they can attach to the surface of particulate matter, and this mechanism is remarked the main transport pathway of PAHs from land and air to aquatic systems, as well as from the sea surface to lower depths (Vagge et al, 2018). Karyab et al (2013) stated that PAHs generally enter water sources through dry and wet deposition, road runoff, leaching from creosote-impregnated wood, industrial wastewater, petroleum spills, and fossil fuels combustion.…”

Polycyclic aromatic hydrocarbons (PAHs) are principally derived from the incomplete combustion of fossil fuels. This study investigated the occurrence of PAHs in aquatic environments around the world, their effects on the environment and humans, and methods for their removal. Polycyclic aromatic hydrocarbons have a great negative impact on the environment and humans, and can even cause cancer in humans. Use of good methods and equipment are essential to monitoring PAHs, and GC/MS and HPLC are usually used for their analysis in aqueous solutions. In aquatic environments, the PAHs concentrations range widely from 0.03 ng/L (seawater; Southeastern Japan Sea, Japan) to 8,310,000 ng/L (Domestic Wastewater Treatment Plant, Siloam, South Africa). Moreover, bioaccumulation of ∑16PAHs in fish has been reported to range from 11.2 ng/L (Cynoscion guatucupa, South Africa) to 4207.5 ng/L (Saurida undosquamis, Egypt). Several physical/chemical and biological techniques have been reported to treat water contaminated by PAHs, but adsorption and combined treatment methods have shown better removal performance, with some methods removing up to 99.99% of PAHs.
