Trophic transfer of dechloranes in marine food webs in Dalian Bay, China

Dechloranes, including dechlorane 602 (Dec 602), dechlorane 603 (Dec 603), dechlorane 604 (Dec 604), dechlorane plus (DP, including syn- and anti-DP) and mirex, were determined in marine food web from Dalian Bay, Northeast China to investigate their occurrence andtrophic transfer. In all organisms,...

Description
Summary:Dechloranes, including dechlorane 602 (Dec 602), dechlorane 603 (Dec 603), dechlorane 604 (Dec 604), dechlorane plus (DP, including syn- and anti-DP) and mirex, were determined in marine food web from Dalian Bay, Northeast China to investigate their occurrence andtrophic transfer. In all organisms, the detection rates were Dec 602 (99%) > mirex (95%) > Dec 603 (92%) > anti-DP (91%) > syn-DP (82%) > Dec 604 (9.6%). The concentrations were 0.92–16 ng/g lipid weight (lw) for mirex, 0.53–2.3 ng/g lw for syn-DP, 1.1–4.5 ng/g lw for anti-DP, 0.19–5.0 ng/g lw for Dec 602, 0.26–1.9 ng/g lw for Dec 603 and 0.020–0.33 ng/g lw for Dec 604. Significant positive relationships (p
