Biota-sediment accumulation factors for Dechlorane Plus in bottom fish from an electronic waste recycling site, South China

Occurrence and biomagnification of organohalogen pollutants in two terrestrial predatory food chains

“…However, using serum as monitor tissue, Yan et al (2012) implied that at least part of the anti-Cl 11 -DP in human serum was derived from the in vivo metabolism of DP. This result was supported by a previous study conducted by Zhang et al (2011), in which a possible hepatic dechlorination of anti-DP in northern snakehead was found according to its significantly greater ratio of anti-Cl 11 -DP to anti-DP in liver than in muscle. In the current study, the average ratios of anti-Cl 11 -DP to anti-DP (mean ± SD) were 0.038 ± 0.024, 0.048 ± 0.035, and 0.011 ± 0.012 for the kestrels, owls and sparrows, respectively.…”

Sex-dependent accumulation and maternal transfer of Dechlorane Plus flame retardant in fish from an electronic waste recycling site in South China

“…As a result of its historical and continued use, tendency for long-range atmospheric transport, and hydrophobicity, DP has been globally detected in the environment Xian et al, 2011). Furthermore, field bioaccumulation parameters indicated that DP isomers can readily be accumulated within biological tissues (Wu et al, 2010;Zhang et al, 2011a;Jia et al, 2011;Shen et al, 2011) and can be biomagnified through food chains (Tomy et al, 2007;Wu et al, 2010). Exposure to DP may elicit ecotoxicological effects to sediment-bearing organisms (OCC, 2004).…”

Dechlorane Plus flame retardant in kingfishers (Alcedo atthis) from an electronic waste recycling site and a reference site, South China: Influence of residue levels on the isomeric composition

“…After that, intensive research of DP occurrence in the environment has been carried out, and revealed that DP is likely environmental ubiquitous, persistent, and bioavailable (see reviews Sverko et al (2011), Xian et al (2011). Bioaccumulation parameters for DP isomers indicate that these chemicals are potentially bioaccumulative and can biomagnify through food webs (Tomy et al, 2007Wu et al, 2010;Zhang et al, 2011b). Recently, a number of DP dechlorinated analogs, e.g., anti-Cl 11 -DP and anti-Cl 10 -DP, were also detected in both abiotic and biotic samples (Sverko et al, , 2010Chen et al, 2011;Wang et al, 2011;Muñoz-Arnanz et al, 2011;Ren et al, 2009;Zheng et al, 2010;Zhang et al, 2011c).…”
