“…For instance, Kang et al (2010), reported DP concentrations from urban-industrial rivers in South Korea (n = 22) in 2008 at an average of 24.5 ng.g -1 lw. Wang et al, in 2010 with an average equal to 29 ng.g -1 lw (Wang et al, 2012). However, our results were close to those reported for Spanish river basins, which ranged from non-detected to 2.24 ng.g -1 lw (Barón et al, 2012) or from non-detected to 4.86 ng.g -1 lw (Santín et al, 2013).…”

Dechlorane related compounds (DRCs), including Dechlorane Plus (syn-DP and anti-DP), Dechlorane-601, -602, -603 and Chlordene Plus (CP), constitute a group of polychlorinated flame retardants (FRs) that are still of industrial use. In particular, DRCs have been detected in various environmental matrices and in different aquatic and terrestrial biota, thus exhibiting bioaccumulation and biomagnification potentials. The present study aimed at producing first occurrence data of a range of DRCs in Silurus spp. samples from different rivers located in France. Determination was carried out by gas chromatography high-resolution mass spectrometry after a sample clean-up based on a multilayer silica column and gel permeation chromatography. The concentration of monitored ΣDRCs ranged from 1.58 to 408 pg g wet weight (54-11100 pg g lipid weight). The fractional abundance of syn- and anti-DP stereoisomers was similar to that reported by other studies with an average equal to 0.60. Dec-601 was not detected in any sample. Detection frequencies ranged between 34 and 100% for other DRCs. Investigated correlations between DRCs and polychlorobiphenyls (PCBs) suggest a link with lipid content but independent contamination sources.

“…In fish, Dec 602 concentrations (3.6e16 ng/g lw) measured in this study were much higher than those in oyster from the Bohai Sea and Huanghai Sea shores in northern China (BDL-5.0 ng/g lw) (Jia et al, 2011) and comparable to those in fish samples (2.2e20 ng/g lw) from the Daling River in northeastern China (Wang et al, 2012), while the DP concentrations (18e440 ng/g lw) found in this study were much higher than those (8.7e93 ng/g lw) from Daling River (Wang et al, 2012). Dechlorane compounds were first identified in the Great Lakes, with the maximum concentrations of dechloranes in Lake Ontario due to the direct riverine input.…”

“…The related studies showed that the variations of f anti in tree bark from remote regions of the world was not changed significantly compared to values in the technical DP (Salamova and Hites, 2012). The f anti value in this study was also similar to those in bark and reed samples from other parts of the world (Table 1) Wang et al, 2012). However, stereoselective enrichment was found in other environmental matrices such as sediment , fish (Wu et al, 2009) and water birds (Zhang et al, 2010).…”

h i g h l i g h t s• The occurrence and distribution of Dechloranes were investigated in the southeast Tibetan Plateau (TP).• DP concentration in southeast TP was much higher than those in moss from the Arctic region.• Different altitudinal patterns between DP and Dec 602 were identified.• Decs are prone to undergo LRAT and cold-trapping by the mountains in the southeast TP. a r t i c l e i n f o t r a c tDechloranes (Decs) have been recently found to occur widely in the environment even in the remote polar regions. However, the understanding of their environmental fate is rather limited. The Tibetan Plateau (TP) may be an important indicator region to study the long-range atmospheric transport and their fates of these emerging contaminants since it has very limited local sources. In the present study, Dechlorane plus (DP), Dechlorane 602 (Dec 602), Dechlorane 603 (Dec 603) and Dechlorane 604 (Dec 604) were analyzed in lichen samples from the southeast TP. The results showed that only DP and Dec 602 were detected, with a detection frequency of 89% and 100%, respectively. The average concentrations (dry weight) of DP and Dec 602 were 318 pg g −1 (20-1132 pg g −1 ) and 167 pg g −1 (27-843 pg g −1 ), respectively. The DP concentration in this study was much higher than those in moss from the remote Ny-Ålesund, Arctic. The concentrations of Dec 602 were found to generally increase with increasing altitude, while DP concentrations seemingly showed an opposite altitudinal trend along the mountain slopes. No stereoselective accumulation or transformation of anti-DP and syn-DP was observed in lichens and the altitudinal behavior of the two isomers was similar. This research documented that Decs are prone to undergo LRAT and cold-trapping by the mountains in the southeast TP.
