“…It has been observed in the Arctic regions and marine environment, indicating its long-range atmospheric transport (LRAT) potential (Möller et al, 2010(Möller et al, , 2012a. DP was also found to bioaccumulate and biomagnify in biota (Peng et al, 2014;Tomy et al, 2007Tomy et al, , 2008Wang et al, 2015;Wu et al, 2010). Recently, Toxicological research indicated that oral exposure to DP can induce hepatic oxidative damage and perturbations of metabolism and signal transduction of male mice .…”

Although Dechlorane Plus (DP) has been used as a polychlorinated flame retardant for almost half a century, its detection in the environment was not reported until 2006. The subsequent intensive research has confirmed its global ubiquity. A few reviews have presented the properties, analytical methods and environmental occurrence of DP and related compounds in the past several years. The present review emphasizes on the environmental behavior of DP isomers which is assessed by the variation of the isomer ratio of DP in various matrices. Other aspects including the analytical methods, emission sources, general environmental occurrence and bioaccumulation of DP are also summarized. In this review, three typical emission sources in the environment are categorized after introducing the measurement method of DP. The temporal-spatial distribution is then evaluated at the global scale, which provides an integrated representation of the environmental occurrence of DP and potential impact on the human health and ecosystems. The variations of DP isomer ratio in various matrices reinforce its source related distribution and their stereoselective bioaccumulation. Thereafter, DP related compounds and dechlorinated analogs are briefly summarized in regards to their occurrence in various matrices, suggesting their ubiquity in the environment and bioavailability. Further studies are required to better assess the exposures and toxicological effects of DP and its analogs. A special concern is the serious contamination in e-waste recycling areas in developing countries, where long-term monitoring data on the association of DP exposure and adverse effects to human health and ecosystems is urgently needed.

“…Concentration levels for CP ranged from ≤ LOD to 45.1 pg.g -1 ww (up to 0.94 ng.g -1 lw) with an average at 2.51 pg g -1 ww (0.11 ng.g -1 lw). These concentrations were lower than those found in seven aquatic species (n = 66) in China in 2010 (100% DF, from 29.8 to 128 ng.g -1 lw,) (Wang et al, 2015). Quite similarly, De la Torre et al 2012reported relatively low mean CP concentrations (0.13 ng.g -1 lw) in dolphin samples off the coast of Brazil (based on half the samples that were quantified).…”

“…Its ubiquitous presence has been confirmed in various environmental matrices all over the world, including wildlife and human, demonstrating that DP is persistent, susceptible to long range atmospheric transport and bioaccumulative (Sverko et al, 2011;Xian et al, 2011). Previous studies have investigated its occurrence and behaviour in the atmosphere (Hoh et al, 2006;Kakimoto et al, 2015;Xian et al, 2011), sediment (Barón et al, 2012;Xian et al, 2011;Yu et al, 2015), soil (Ma et al, 2014), water (Sverko et al, 2011), biota (L'Homme et al, 2015;Rjabova et al, 2016;Wang et al, 2015;Zhang et al, 2011) as well as food products (Aznar-Alemany et al, 2016;Kakimoto et al, 2012;Kim et al, 2014). Sverko et al (2011) even suggested, considering DP in Annex D (candidate list) of the Stockholm Convention, so that such compounds are of public safety concerns.…”

Occurrence of Dechlorane Plus and related compounds in catfish (Silurus spp.) from rivers in France

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.

“… 27 , 28 For Dec602 and Dec603, the values reported here are higher (6.6 vs. 3.7) 27 and much higher (12.4 vs. 1.3), 28 respectively, than previously reported values. For syn -DP and anti -DP, the previously reported values range from −0.79 to 2.9, 27 , 30 , 31 and from 0.59 to 3.3, 27 , 29 − 31 respectively. The corresponding (nonsignificant) values reported here were 2.5 and 2.4, which are within ranges of the cited values.…”

To enhance knowledge of the environmental distribution and temporal trends of dechloranes and their transformation products (TPs) we performed suspect screening of Baltic Sea biota (eelpout, herring, harbor porpoise, guillemot and white-tailed sea eagle). Evaluation of new and “digitally frozen” gas chromatography/high-resolution mass spectrometry data revealed 31 compounds: five dechloranes (Dechlorane [Mirex], Dechlorane 602, Dechlorane 603, and syn -/ anti -Dechlorane Plus [DP]), three isomers, and 23 TPs. Six new Dechlorane 603 TPs and two new DP TPs were detected, including one hydroxy-TP. Some TPs occurred at much higher concentrations than the parent compounds (e.g., Dechlorane 603 TPs were >10-fold more abundant than their parent). Concentrations of contaminants in the most contaminated species (white-tailed sea eagle) changed little over the period 1965–2017. Slow declines were detected for most compounds (median, 2% per year), although concentrations of DP and DP-TPs increased by 1% per year. Ten contaminants biomagnify, and the trophic magnification factors for TPs of Mirex, Dechlorane 602 and Dechlorane 603 (8.2 to 17.8) were similar to the parent compounds (6.6 to 12.4) and higher than that of DP (2.4, nonsignificant). The results are discussed in relation to the current review of DP for potential listing under the Stockholm Convention on POPs.
