“…Therefore, anthropogenic activities are the main cause for the occurrence of n ‐alkanes in the PRD, with minor contributions from high plant waxes. Furthermore, the particulate samples had a higher CPI 2 (1.9 ± 0.82) than the dissolved samples phase (1.5 ± 1.3; p < 0.05), suggesting that compared to LMW components, HMW n ‐alkanes from terrestrial high plant waxes are transported more readily with particulate matter, also as described previously [11,21,22]. On the other hand, the odd‐even carbon number preference value ranged from 0.3 to 3.3 (mean, 1.1) in the present study.…”

“…Compared with other aquatic systems, the particulate concentrations of ⌺(C 15 -C 34 ) from the present study were significantly higher than those of ⌺(C 16 -C 36 ) found on Kara Sea shelves [10]. The ⌺(C 15 -C 34 ) values from the present study were similar to the ⌺(C 15 -C 35 ) values in the Rhone River (France; 0.17-2.8 g/L) and the Yangtze River (China; 0.18-2.02 g/L) but were relatively lower than the levels in the Yellow River (China) [11].…”

Riverine runoff samples were collected monthly from March 2005 to February 2006 from the eight major outlets of the Pearl River Delta (PRD), South China, and analyzed to obtain the concentrations of n-alkanes in both the filtrate and particulate phases. The average concentrations of Sigma(C15-C34) (i.e., sum of C15 to C34 normal alkanes) ranged from 0.06 to 2.97 microg/L (mean, 0.64 microg/L) in filtrate samples and from 1.00 to 98.8 microg/g (average, 19.8 microg/g dry weight) in particulate samples. Compared to results from around the world, the levels of hydrocarbon compounds in the PRD were at the high end of the global range. Evaluation of compositional indices of n-alkanes indicated that petroleum-related sources are the main contributor of n-alkanes found in the PRD, with minor contributions from high plant wax. Regression analyses appeared to suggest that n-alkanes are transported into the aquatic environment of the PRD via various pathways, and the transport mechanisms also are considerably influenced by the complex hydrologic conditions in the PRD. The annual riverine input of Sigma(C15-C34) from the PRD to the coastal ocean was 360 tons/year, or the equivalent of approximately 8,800 tons/year of petroleum hydrocarbons. The emission of Sigma(C15-C34) from all sources in the PRD was estimated at 39,000 tons/year, or 2.4 g/day per capita. Overall, the PRD contributes approximately 0.2% of the annual global input of n-alkanes to the coastal oceans, similar to the contributions of polycyclic aromatic hydrocarbons, further indicating that the PRD has been a significant source of hydrocarbon contamination to the global coastal marine environment.

“…Therefore, river influence appears as a very determinant factor for the distribution of sedimentary hydrocarbons in the Guipuzcoan Coast. In principle, this conclusion could be expected in view of previous studies on the marine distribution of river-transported pollutants (47,69,70). However, the results of Figure 6a are free from predetermined assumptions and provide an error probability for the recognition of the organic pollution load of each river over the dispersion associated with natural processes (e.g., waves, currents, and particle sedimentation) and experimental measurements (e.g., sampling and analysis).…”

“…In addition, they are subject to long-range transport and have been detected in remote areas where they have never been used [4,5] . Since atmospheric transport is the principal vehicle for the movement and global distribution of these chemicals, significant efforts are being made on identifying their ambient sources [6][7][8][9] , transport pathways [4,10,11] , and fate [12][13][14] . Until recently, there was a paucity of reliable environmental data on the levels of most POP chemicals in the Middle East, most of Africa, and Asia, from which to assess the effectiveness of international efforts to minimize the release of these chemicals to the environment.…”

This study compared the concentration of persistent organic pollutants (POPs) in air derived from polyurethane-based passive samplers to those of hair samples collected from humans and sheep. Human scalp hair samples were obtained from 24 healthy individuals and ten sheep (Ovis aries) during indoor and outdoor polyurethane foam plug ambient sampling. The samples were analyzed for polycyclic aromatic hydrocarbons (PAHs) and polybrominated diphenyl ethers (PBDEs). ∑PBDE concentrations ranged 0.6-50 ng·g-1 (mean, 18.6 ± 13 ng·g-1) for humans and 0.6-1.4 ng·g-1 (mean, 1.1 ± 0.25 ng·g-1) for sheep. The ∑PAH concentrations were log-normally distributed in human hair ranging 98-2529 ng·g-1 (mean, 460 ± 538 ng·g-1), whereas concentrations for sheep hair samples ranged 168-526 ng·g-1 (mean, 334 ± 117 ng·g-1). Strong correlations (P-values < 0.01) were found between concentrations of PAHs and PBDEs in human and sheep hair with concentrations measured in indoor and outdoor air, respectively. Evidence generated from this preliminary study suggests that hair might be used for the environmental monitoring of POPs in remote sites to provide a first-order estimate of ambient levels. Further studies are required to understand the uptake profiles and validate the use of hair as a sampling medium for POPs in ambient air.
