“…14,15 Phenanthrene is released to the environment via several routes, including petrochemical effluents, pipeline leakages, leachates from landlls, and indiscriminate waste disposal. 16 Adsorption, extraction, bioremediation, chemical oxidation and photocatalytic degradation are the common conventional methods used to remove PAHs present in water. 17 Adsorption has been widely used due to its simplicity, ease of operation, high processing efficiency, and high removal rates for most pollutants.…”

“…[2][3][4] PAHs are comprised of two or more benzene rings bonded in differently shaped arrangements. 5 Furthermore, 16 PAHs have been categorised as priority contaminants based on possible human exposure, level of toxicity, and the extent of information available. 6 Amongst these PAHs is phenanthrene due to its potential mutagenicity, carcinogenicity, toxicity, and bioaccumulation.…”

“…Because of the low solubility in water, PAH compounds accumulates in the sediment at the bottom of the water. Due to the fact that sea creatures such as crab, lobster, shrimp, mussel, many fish species and algae that are buried in the sea bottom, are fed by filtering into their bodies, they accumulate PAH compounds in their tissues over time (Nwaichi and Ntorgbo 2016;Ololade et al 2017;Yang et al 2013;Zhang et al 2015). Among these sea creatures, seaweed enters the body of people with food chain because its consumption as a foodstuff by many cultures.…”

Polycyclic aromatic hydrocarbons (PAHs) are often measured in the atmosphere for air grade valuation, and sea creatures for environmental monitoring, in residue and for safety cases in food materials, in biological tissues for health-effects monitoring. In this study, Polycyclic aromatic hydrocarbon (PAH) concentrations in algae of Ulva rigida species, as an environmental indicator, in the spring of 2019 were collected from eigh station in Giresun costline in May. In general, algae samples are extracted by methanol solutions with Soxhlet apparatus. By applying the necessary purification processes to the obtained solution, the concentrations of 16 PAH components were determined with the GC/MS device. The amount of most of the 16 PAH compounds in the Keşap coast algae samples was the highest. The highest amount compounds are found to phenanthrene, fluorene and anthracene, and it is high in Bulancak, Giresun-Central and Keşap sites. It belongs to seaweed samples collected from Piraziz site, which has the lowest values among eight stations. The PAH compound concentration is determined 0.08-340.96 ppb values. In the spring sampling, the lowest value is Espiye and Tirebolu stations with Benzo[a]pyrene compound and the highest value is Keşap station with Phenanthrene compound. Since the benzo [g,h,i]perylene is lower than the detection levels in many stations. The main origins of PAHs were found as both pyrolytic and petrogenic at most stations.

“…Polycyclic aromatic hydrocarbons (PAHs), which are the result of incomplete combustion of organic materials (Ololade et al 2017; Zhang et al 2017a, b), are also classified as persistent organic pollutants. PAHs are a group of ubiquitous environmental compounds with persistent toxic abilities known to bioaccumulate in the environment due to slow decomposition (Joyce et al 2016; Li et al 2017).…”

The Lower Fox River is a 39 mile section which supports approximately 270,000 rural inhabitants across 18 counties, 303,000 metropolitan residents in Green Bay and Appleton, Wisconsin, and several large industrial complexes such as paper mills and power plants. This paper presents the distribution and concentrations of aliphatic (n-alkanes) and aromatic hydrocarbons (polycyclic aromatic hydrocarbons [PAHs]) as well as total organic carbon (TOC) in the Lower Fox River to identify the sources of hydrocarbon contamination. Excluding one outlier, percent TOC values were between 0.73 and 19.9% with an average value of 6.74%. Total n-alkanes ranged from 3.51 μg/g to 117 μg/g and showed a strong presence of odd carbon-numbered n-alkane ratios (range of C25 to C35), suggesting source input from terrestrial biomass. The mean polycyclic aromatic hydrocarbon (PAH) concentration was 24,800 ng/g. High molecular weight PAH concentrations dominated the distribution of hydrocarbon contaminants. Cross-plots of PAHs were used to compare diagnostic source ratios of benz[a]anthracene (BaA), chrysene (Chr), fluoranthene (Flu), pyrene (Pyr), anthracene (Ant), phenanthrene (Phe), indeno[1,2,3-cd]pyrene (InP), and benzo[g,h,i]perylene (BghiP) by depth and area. PAH ratios varied slightly with the core depth. Deeper core sections indicated the presence of biomass combustion while the upper core sections indicated combustion of both petroleum and biomass. The PAH toxicity of one core was estimated using toxicity equivalency factors, and the benzo[a]pyrene toxic equivalence quotient totaled 2,293 ng/g-dry wt. Levels of PAHs in sediments are compared with established regulatory values and recommendations are made.
