“…Dechlorane Plus (DP) is mainly used as a flame retardant in electronic components, paints, and polymer products (Hoh et al 2006). Its commercial mixture consists of 2 major isomers (syn‐DP and anti‐DP), with global annual production of 450 to 4500 tons (Wang et al 2020), and it has been determined to be persistent, toxic, and bioaccumulative (Environment and Climate Change Canada 2019). In the 15th meeting of the Review Committee for the Stockholm Convention on Persistent Organic Pollutants, it was decided that DP met the persistent organic pollutant screening criteria (Annex D review; United Nations 2019).…”

“…The biomagnification of DP has been reported in aquatic food webs, but rarely examined in terrestrial food webs. The latter is critical because DP can be transferred to humans through the soil–crop–livestock–human route (Sun et al 2019), and may reach concentrations in human tissues that pose health risks (Pan et al 2002), as it interferes with the endocrine system and damages DNA and tissues (Wang et al 2020).…”

Dechlorane Plus (DP) is found widely in the environment. It is important to study DP enrichment and biomagnification in terrestrial ecosystems to improve our understanding of the possible effects of DP on the environment and human health. A total of 90 samples, including plant and animal tissues, were collected from Xilingol Prairie in Inner Mongolia, China. The DP concentrations in different species were assessed, and transmission of DP through food webs containing ectotherms and endotherms was assessed. The compound was detected in the biotic samples (plant; range 0.133–0.422 ng/g dry wt), in animal muscle (range: not dected–5.70 ng/g lipid wt), and in animal hair (range: not dected–2.03 ng/g dry wt), indicating that DP is present in remote environments such as Xilingol Prairie. These findings suggest that DP can undergo long‐distance transport in the environment. Biomagnification factors (ectotherms: range 0.146–88.0, endotherms: range 0.866–17.2) and anti‐DP/total DP concentration ratios (fanti values of 0.412–0.787) for the prairie animals were calculated. Ectotherms were found to selectively enrich syn‐DP, and stereoselective enrichment increased moving up the food web. Lower‐trophic‐level endotherms strongly stereoselectively enriched syn‐DP, and higher‐trophic‐level endotherms stereoselectively enriched anti‐DP. Environ Toxicol Chem 2021;40:413–421. © 2020 SETAC
