TL;DR: Water samples collected in two streams and a lake located at Niteroi City, Rio de Janeiro State, Brazil between October 2008 and September 2009 showed a seasonal variation in wet and dry seasons indicating a possible role of runoff to local pollution of water by PAHs.

Diverse toxicological risks of PAHs in surface water with an impounding level of 175 m in the Three Gorges Reservoir Area, China
TL;DR: This study probes the ubiquitous polycyclic aromatic hydrocarbons (PAHs) contamination and toxicological impacts in the surface water of the TGRA at the highest water impoundment level of 175m to reveal the real status of ecological toxicity of PAHs and explore the underlying mechanisms.

Source apportionment and seasonal cancer risk of polycyclic aromatic hydrocarbons of sediments in a multi-use coastal environment containing a Ramsar wetland, for a Caribbean island.
TL;DR: PAH levels were observed to be significantly higher in the wet season compared to the dry season and in the areas where natural gas is the dominant energy source for industries, compared with those areas where crude oil-based fossil fuel is predominantly used.

Molecular characterization of PAHs based on land use analysis and multivariate source apportionment in multiple phases of the Yangtze estuary, China.
TL;DR: PAH pollution in the study area was primarily of terrestrial origin, and urban and agricultural land use and river systems along the estuary were the major input pathways for the PAH loadings.

TL;DR: In this article, low density polyethylene passive samplers were deployed in upland surface waters and the overlying atmosphere in subtropical and tropical mountain regions in south and southeast Brazil, respectively, to determine the concentrations, transport and sources of freely dissolved and gaseous polycyclic aromatic hydrocarbons (PAHs) along altitudinal gradients.

TL;DR: The hydrocarbon composition of atmospheric particulate matter (PM) and Volatile Organic Compounds (VOC) from urban areas of Rio de Janeiro City were studied to assess different pollution levels.

PAHs in the Fraser River basin: a critical appraisal of PAH ratios as indicators of PAH source and composition
Mark B. Yunker,Robie W. Macdonald,Roxanne Vingarzan,Reginald H. Mitchell,Darcy Goyette,Stephanie Sylvestre +5 more
TL;DR: In this paper, parent and alkyl PAHs were quantified in suspended particulates and sediments (345 samples) from the Fraser River system, British Columbia, Canada, and the best potential to distinguish natural and anthropogenic sources is exhibited by ratios of the principal mass 178, 202, 228 and 276 parent PAH, 1,7/2,6+1,7-DMP (dimethylphenanthrene), the phenanthrene/anthracene and fluoranthene/pyrene alkyal PAH series and several less commonly applied PA

Polycyclic aromatic hydrocarbons (PAH) in seawater around England and Wales
TL;DR: In this paper, surface seawater samples collected during the period 1993-1995 from 177 stations around England and Wales have been analysed for 15 individual parent PAH compounds, using high-performance liquid chromatography with fluorescence detection.

Occurrence of priority hazardous PAHs in water, suspended particulate matter, sediment and common eels (Anguilla anguilla) in the urban stretch of the River Tiber (Italy)
TL;DR: Some selected PAH ratios indicated that PAHs in the River Tiber come mainly from pyrolitic sources and vehicular traffic, suggesting no concern for human consumption.

Distribution of polycyclic aromatic hydrocarbons in water and bed sediments of the Gomti River, India.
TL;DR: Principal component analysis separated the PAHs sources in the river sediments, suggesting that both the pyrolytic and petrogenic sources are contributing to thePAHs burden.
