“…It could be via effluents, atmospheric fallout, and urban runoff. Interestingly, similarly predominant individual PAH was observed in water of these rivers in different areas, Phen, and/or Naph accounting for about 45 % of total PAHs on average (Song et al 2010;Li et al 2010;Feng et al 2007;Luo et al 2009). Phen is the characteristic PAHs of coal combustion, and Naph is a highly volatile matter.…”

“…According to different areas, the PAHs contamination level followed the order: heavy industrial areas (Taizi River, Hun River) > urban/industrial areas (rivers in Tianjing, Wuhan section of Yangtze River) > agricultural areas (Luan River, Hongfeng Lake; Song et al 2010;Li et al 2010;Feng et al 2007;Luo et al 2009), suggesting that industrial activities contribute a majority of PAHs in water. However, the approaches of PAHs into rives are various.…”

The objectives of this study were to investigate the levels, dispersion patterns, seasonal variation, and sources of 16 priority polycyclic aromatic hydrocarbons (16 EPA-PAHs) in the Hun River of Liaoning Province, China. Samples of surface water were collected from upstream to downstream locations, and also from the main tributaries of the Hun River in dry period, flood period, and level period, respectively. After appropriate preparation, all samples were analyzed for 16 EPA-PAHs. Total PAHs concentrations varied from 124.55 to 439.27 ng l(-1) in surface water in dry period, 1,615.75 to 5,270.04 ng l(-1) in flood period, and 2,247.42 to 7,767.9 ng l(-1) in level period. The 16 EPA-PAHs concentrations were significantly increased in the order of level period > flood period > dry period. The composition pattern of PAHs in surface water was dominated by low molecular weight PAHs, in particular two- to three-ring PAHs. In addition, two-ring PAH accounted for 39.33 to 88.27 % of the total PAHs in level period. Low molecular weight PAHs predomination together with higher levels of PAHs in flood and level period suggested a relatively recent local source of PAHs. Special PAHs ratios such as phenanthrene/anthracene and fluoranthene/pyrene indicated that under dry weather season conditions, the PAHs found in surface water were primarily from petrogenic source, while under wet weather season conditions they were from mixed source of both petrogenic inputs and combustion sources. The comparison of PAHs contamination among different types of areas in China suggested that atmospheric depositions might be the most important approaches of PAHs into water system. Although the Hun River exists low PAHs ecological risk now, potential toxic effects will be existed in the future especially in flood and level period.

“…In the Tumen River, the seasonal PAH variability is similar to the trend found for some water bodies located at latitudes similar to the areas under study. An increase in TPAHs was found in the warm, wet period, explained by a higher run-off PAH input due to heavy precipitation, as well as greater solubility of PAHs at elevated temperatures [32,33]. Accordingly, in the summer, when the greatest amount of precipitation was recorded, the highest TPAHs were found for the Tumen river.…”

The seasonal polycyclic aromatic hydrocarbon (PAH) variability was studied in the estuaries of the Partizanskaya River and the Tumen River, the largest transboundary river of the Sea of Japan. The PAH levels were generally low over the year; however, the PAH concentrations increased according to one of two seasonal trends, which were either an increase in PAHs during the cold period, influenced by heating, or a PAH enrichment during the wet period due to higher run-off inputs. The major PAH source was the combustion of fossil fuels and biomass, but a minor input of petrogenic PAHs in some seasons was observed. Higher PAH concentrations were observed in fresh and brackish water compared to the saline waters in the Tumen River estuary, while the PAH concentrations in both types of water were similar in the Partizanskaya River estuary, suggesting different pathways of PAH input into the estuaries. The annual riverine PAH mass flux amounted to 0.028 t/year and 2.5 t/year for the Partizanskaya River and the Tumen River, respectively. The riverine PAH contribution to the coastal water of the Sea of Japan depends on the river discharge rather than the PAH level in the river water.

“…The PAH concentrations observed in aquatic systems differ seasonally, due to the variability of factors such as rainfall amount, input sources and strengths, ease of degradation, and content of suspended solids. − Although many studies report higher PAH concentrations in colder months as a result of increased heating-related combustion sources and reduced degradation, a few report relatively high concentrations in the summer, attributed to increased wet deposition and runoff during this season. ,, These studies indicate that the amount of rainfall (and runoff) could sometimes be the major driver of PAH concentration in rivers and streams. This effect is especially evident with a decrease in seasonal variability in PAH source strength, for example, in tropical regions (which do not require winter heating).…”

Polycyclic Aromatic Hydrocarbons and Quinones in Urban and Rural Stormwater Runoff: Effects of Land Use and Storm Characteristics

et al. 2021

Changes in streamwater concentrations in two creeks draining contrasting urbanized landscapes in southern Ontario, Canada, during a major summer rainfall event were used to assess how land use and emission sources influence the fate and behavior of polycyclic aromatic hydrocarbons (PAHs) and quinones (PAQs) in a watershed. By comparing three rainfall events during different seasons, we further explored the influence of seasonal variability, rainfall/runoff amount, and antecedent dry period on PAH behavior. The analysis of concentration–discharge (C–Q) relationships revealed that during a warm weather precipitation event, PAHs and PAQs behaved similarly, had common sources, and were predominantly transported via suspended solids. The importance of land use and emission intensity was reflected in higher concentrations of PAHs and PAQs in the more urbanized creek. PAH loads in that watershed were up to 2 times higher during cold weather events than during the summer event. PAH loads also increased with an increase in runoff ratio and a longer antecedent dry period, suggesting that the flushing of surfaces on which solids had accumulated was an important process for the delivery of PAHs to the streams. In the less urbanized watershed, variation in PAH behavior between events was minor, evidenced by similar C–Q patterns and small differences in PAH loads.
