“…Zhu et al (2014) found a significant positive temporal shifting trend of the ratio of DP to BDE-209 between 2003 and 2012 in IndoPacific humpback dolphins (Souse chinensis) (r = 0.67, p = 0.0005) and finless porpoises (Neophocaena phocaenoides) (r = 0.82, p b 0.0001) from the South China Sea, indicating a use-shift from PBDEs to other alternatives such as DP in China. Whereas, the temporal trend of DP in these biotas was not mentioned (Zhu et al, 2014). A very recent work by Barón et al (2015) indicated that DP levels in the unborn eggs of three species (black kite, white stork and greater flamingo) from …”

“…Liquid chromatography-tandem mass spectrometer system (LC-MS/MS) with an atmospheric pressure chemical ionization (APCI) interface was also reported to successfully measure halogenated flame retardants including DP in marine mammals (Zhu et al, 2013(Zhu et al, , 2014. Chromatographic separation was performed on a Zorbax SB-C18 column, and the mobile phase consisted of methanol/water (85:15) and methanol.…”

“…The method detection limits (MDLs) for DP were reported at the level of pg m − 3 in air Möller et al, 2012a,b;Xiao et al, 2012), pg L −1 in water Na et al, 2015;Qi et al, 2010;Venier et al, 2014), pg g −1 dry weight (dw) in soil and sediment (Barón et al, 2012(Barón et al, , 2014aMa et al, 2011;Qi et al, 2010;Shen et al, 2011a,b;Wang et al, 2010a,b), and ng g −1 lipid weight (lw) in biota samples Peng et al, 2015;Salamova and Hites, 2013;Yan et al, 2012;Zhang et al, 2011aZhang et al, , 2015Zhu et al, 2014), respectively. Even lower MDL values were obtained in fish (pg g −1 lw) when using GC-NCI-MS/MS and GC-EI-HRMS (Barón et al, 2012;Shen et al, 2010Shen et al, , 2011a, which guaranteed the detection of DP with lower levels in the background areas.…”

“…The awareness of its spatial distribution benefits from the rapidly increasing research on the subject in the last decade, while data on its temporal trends are mainly limited to the North American Great Lakes region except for some studies from Spain and China (Barón et al, 2015;Zhu et al, 2014). There seems to be a consensus that DP shows most characteristics of POPs, such as environment persistency, bioaccumulation and LRAT potential.…”

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.

“…The two cetacean species have been the subjects of our previous studies, which indicated that both of them are susceptible to exposure and bioaccumulation of persistent halogenated contaminants due to their longevity, high trophic position, and body fat content. 32,33 China has a region-specific production history of CPs, and Asia-Pacific countries offer the largest market demand for the industrial chemicals. To better understand the current pollution status of CPs in the marine environment, the present study aimed to identify and quantify SCCPs and MCCPs in the blubber of these two species of marine mammals from the South China Sea, to reveal the primary sources, and to assess their temporal trends and homologue pattern changes from 2004 to 2014.…”

Temporal trends of short-(SCCPs) and medium-chain chlorinated paraffins (MCCPs) were examined in blubber samples of 50 finless porpoises (Neophocaena phocaenoides) and 25 Indo-Pacific humpback dolphins (Sousa chinensis) collected from the South China Sea between 2004 and 2014. Elevated levels of SCCPs and MCCPs were detected in all blubber samples of both cetacean species. Concentrations of SCCPs ranged from 280 to 3900 ng·g −1 dry weight (dw) in porpoises and from 430 to 9100 ng·g −1 dw in dolphins, while concentrations of MCCPs ranged from 320 to 8600 ng·g −1 dw in porpoises and from 530 to 23 000 ng·g −1 dw in dolphins. Significantly higher concentrations were present in dolphins than porpoises due to their exposure levels in their living habitats. Strongly linear correlations existed between SCCPs and MCCPs, but there were no significant concentration differences between the genders of the two cetacean species in the same sampling year. Significantly temporal increasing trends of ∑SCCPs and ∑MCCPs have been observed in both porpoise and dolphin samples over the past decade, which reflect the influence of histories of production and usage on the bioaccumulation of CPs in marine mammals in China. An apparent temporal shift trend from SCCPs to MCCPs was also observed in CP accumulation profiles. Complex environmental fractionation from localized sources in the study region via atmospheric transport, oceanic/offshore water transport, and trophic transfer have resulted in different CP accumulation levels and homologue patterns in the two cetacean species. This is the first report of systematic temporal trends of SCCPs and MCCPs in marine mammals.
