PAHs with 3, 4, and 5 rings usually dominate emissions from both wood-burning and vehicle exhaust, because larger molecules tend to be incorporated into soot particles (Richter and Howard 2000).…”

“…Once the PAHs enter the marine environment, they can then readily be taken up by marine biota (Perugini et al 2007;Martinez-Gomez et al 2010;Liu et al 2015) either through their gills or via ingestion (Baumard et al 1999). The main mechanism underlying toxicity of PAHs is their direct binding to hydrophobic sites of macromolecules such as lipids, proteins, and nucleic acids, interfering with their normal functioning (Vijayavel et al 2004;Pampanin and Sydnes 2013).…”

Polycyclic aromatic hydrocarbons (PAHs) have garnered much attention due to their bioaccumulation, carcinogenic properties, and persistence in the environment. Investigation of the spatial distribution, composition, and sources of PAHs in sediments of three recreational marinas in San Diego Bay, California revealed significant differences among marinas, with concentrations in one site exceeding 16,000ngg. 'Hotspots' of PAH concentration suggest an association with stormwater outfalls draining into the basins. High-molecular weight PAHs (4-6 rings) were dominant (>86%); the average percentage of potentially carcinogenic PAHs was high in all sites (61.4-70%) but ecotoxicological risks varied among marinas. Highly toxic benzo(a)pyrene (BaP) was the main contributor (>90%) to the total toxic equivalent quantity (TEQ) in marinas. PAHs in San Diego Bay marina sediments appear to be derived largely from pyrogenic sources, potentially from combustion products that reach the basins by aerial deposition and stormwater drainage from nearby streets and parking lots.

“…LMW-PAHs concentrations were progressively decreased by dilution due to their high water solubility and easier degradation. Therefore, HMW compounds had a higher resistance to degradation and could easily reach the sediment due tothe low water solubility, low vapour pressure, and refractory behavior [41,[67][68][69].…”

This study reports the data on the contamination caused by polycyclic aromatic hydrocarbons (PAHs) drained from the Volturno River. The seasonal and spatial distribution of PAHs in water and sediment samples was assessed. The 16 PAHs were determined in the water dissolved phase (DP), suspended particulate matter (SPM), and sediments. A multidimensional statistical approach was used to identify three pollution composite indicators. Contaminant discharges of PAHs into the sea were calculated in about 3158.2 kg/year. Total concentrations of PAHs varied in ranges 434.8 to 872.1 ng g−1 and 256.7 to 1686.3 ng L−1 in sediment samples and in water (DP + SPM), respectively. The statistical results indicated that the PAHs mainly had a pyrolytic source. Considering the sediment quality guidelines (SQGs), the water environmental quality standards (USEPA EQS), and risk quotient (RQ), the Volturno River would be considered as an area in which the environmental integrity is possibly at risk.

“…The present study focused on analyzing transcriptomic profiles in zebrafish exposed to the surface water, with the aim to evaluate the impacts of complex mixtures of pollutants at environmentally relevant concentrations on aquatic vertebrates, as well as to elucidate the potential of transcriptomic profiles to differentiate pollution sources, and to identify the toxic components. The Hun River is a main tributary located in the Liao River basin, flowing through the city of Shenyang which is the capital of Liaoning Province and one of the most important industrial cities in China [16,19]. The Dongzhou River and Xi River, two main tributary flowing into Hun River, have been identified as the receiving water of chemical wastewater and pharmaceutical wastewater, respectively [20,21].…”

The present study aims to evaluate the potential of transcriptomic profiles in evaluating the impacts of complex mixtures of pollutants at environmentally relevant concentrations on aquatic vertebrates. The changes in gene expression were determined using microarray in the liver of male zebrafish (Danio rerio) exposed to surface water collected from selected locations on the Hun River, China. The numbers of differentially expressed genes (DEGs) in each treatment ranged from 728 to 3292, which were positively correlated with chemical oxygen demand (COD). Predominant transcriptomic responses included peroxisome proliferator-activated receptors (PPAR) signaling and steroid biosynthesis. Key pathways in immune system were also affected. Notably, two human diseases related pathways, insulin resistance and Salmonella infection were enriched. Clustering analysis and principle component analysis with DEGs differentiated the upstream and downstream site of Shenyang City, and the mainstream and the tributary sites near the junction. Comparison the gene expression profiles of zebrafish exposed to river surface water with those to individual chemicals found higher similarity of the river water with estradiol than several other organic pollutants and metals. Results suggested that the transcriptomic profiles of zebrafish is promising in differentiating surface water with pollution gradient and different discharges and in providing valuable information to support discharge management.
