“…Near-shore coastal areas such as estuaries are typically subject to a variety of stressors, both natural and anthropogenic, which can impair the health and fitness of resident biota (Salazar-Coria et al, 2010). To be able to ensure healthy, safe and prosperous oceans for the benefit of current and future generations, an ecosystem-based management is need to support sustainable developments, while taking into account the Precautionary Principle (Hellou et al, 2006;Council Directive, 2008/56/EC, 2008.…”

An integrated study has been carried out of the fate and effects of PAHs in fish living in a chronically polluted environment. Total PAH concentrations in different target organs (muscle, liver and gills), have been determined in five species of feral fish and possible histopathological effects and correlations of all these values with concentrations found in sediments and water column have been studied in two of these species. The Potency Equivalent Concentrations and Screening values (SVs), the Biota-to-sediment accumulation factors (BSAFs) and the Toxic Potency Assessment (TEQ) of sediment for fish have been calculated. Results show that levels found in target organs, the TEQs of sediment calculated for fish related to the SVs for fish consumption are of special concern. However, the index of pathologies shows a relatively low impact of PAHs on fish health. The use of feral finfish in risk assessment for PAHs in chronically polluted environments has been proved to be a useful tool to complement environmental diagnoses and improve their accuracy. This approach combines the measurement of total concentrations in different target organs of several appropriate species, the study of histopathological effects, and correlations between all these results and the concentrations found in associated sediments and column water.

“…The strong petrogenic influence on PAH signatures in biota from the Indiana Ship Canal is not surprising, given that an oil refinery and a large number of petroleum storage tanks are located adjacent to the canal (JML pers obs); groundwater and surface waters there are heavily contaminated with petroleum (USEPA 2009). Salazar-Coria et al (2010) calculated TEQ of the sediment by multiplying geometric-mean sediment concentrations by fish potency factors derived by Barrona et al (2004) from CYP1A induction and AhR binding data. We multiplied TEFs (Table 1) by the sediment concentrations to give the following TEQ sediment : ISC (17.64); IRMsh (5.87); LCalR (2.8); and BgMsh (0.54).…”

We identified and quantified polyaromatic hydrocarbons (PAHs) in six aquatic taxa from the Calumet region of southwestern Lake Michigan in order to examine their differential exposure to and health risks from PAH. There was a high degree of variation in PAH concentrations across and within sites. Mean concentrations of total PAH were high in alewife (1,064 ng/g) and minnows (345 ng/g) collected from the Indiana Ship Canal, when compared to other taxa and locations. Concentrations of PAH in sunfish were relatively low (10 to 79 ng/g), even where environmental concentrations were elevated. In sunfish, regardless of location, concentrations of CHR, FLA, FLU, PHE and PYR were high whereas DBA, IPE, BAP, BBF, BGP and BKF concentrations were low. PAH concentrations in crayfish exceeded those of other taxa at three of four locations where they co-occurred. PAH profiles were similar in crayfish, sunfish and minnows from locations where sediment concentrations were low. Profiles for crayfish and minnows from a location where sediment concentrations were elevated displayed lower concentrations of ACY, and higher concentrations of BAA, BBF, and BKF, than those from the other three locations. In contrast, the profiles in sunfish from those three locations were similar. The PHE/ANT and FLA/PYR ratios for crayfish, minnows and sunfish suggested that the primary sources at most locations were pyrogenic, although some sites had strong petrogenic influences. Toxic equivalency factors in biota generally reflected the magnitude of sediment contamination. In three of four locations where they co-occurred, TEQs were higher in crayfish than in sunfish and minnows. Sunfish had higher TEQs than minnows at most, though not all, locations; TEQs were notably higher in minnows as compared to sunfish from the Little Calumet River. The selection of aquatic species as sentinels of PAH exposure and risks needs to consider differences in ecologies of taxa as well as the relative magnitude of sediment contamination.

“…Most toxic effects of PAHs are derived from studies on other organisms (8)(9)(10)(11). Nonetheless, because of the similarity of biological systems in different species, it is likely that all mammals, including humans, will be affected in a similar way.…”

This article covers the status of PAH concentrations and composition patterns in surface water, air, sediment, and soil samples from South Africa. Despite South Africa being one of the largest economies in Africa, it is only recently that researchers have reported the presence and possible sources of these compounds in various environmental compartments. This article discusses the potential hotspots and possible sources of these compounds. It also compares the total PAH concentrations and percentage composition patterns of the individual PAHs. So far, total concentrations of five PAHs determined in sediment samples from the Johannesburg area, Gauteng Province, gave the highest concentrations ranging from 1233-136, 276 μg kg −1 . The total concentration of six PAHs found in runoff water from the Venda region of the Limpopo Province, gave the highest concentration with a range of 28.7-3192.6 μg L −1 . The decreasing order of percentage composition of PAHs in water samples tended to follow 3-ring > 4-ring > 2-ring PAHs. In soil samples the decreasing order of percentage composition followed 4-ring > 3-ring > 5-ring > 2-ring > 6-ring PAHs. The total freely dissolved PAHs followed solubility of the compounds with 2-ring > 3-ring > 4-ring > 5-ring > 6-ring PAHs. Some of the identified sources of PAHs using molecular ratios include petrogenic emissions such as from petroleum combustion from vehicles and pyrolytic sources such as coal combustion by coal powered power stations, as well as iron and steel production industries. Oil spills were also identified as major PAH contributor in runoff water from the Venda region of the Limpopo Province.
