Fish samples purchased from Japanese markets were analyzed for Dechlorane Plus (DP)(syn-, anti-), polybrominated diphenyl ether (PBDE), and hexabromocyclododecane (HBCD)(α, γ). Twenty fish were analyzed using gas chromatography-mass spectrometry for DP and PBDE, and using liquid chromatography-tandem mass spectrometry for HBCD. DP was detected in 18 samples and ∑DP concentrations were <0.2-14.2 pg g(-1)wet wt. Among the DP isomers, anti-DP was the dominant residue observed in this study. PBDE was detected in all samples. Concentrations of ∑PBDE ranged from 2.2 to 878 pg g(-1) wet wt. HBCD was detected in 18 samples, and ∑HBCD concentrations were <0.02-21.9 ng g(-1)wet wt. In fish landed near the East China Sea and the Sea of Japan, we detected relatively high concentrations of DP, PBDE, and HBCD. These results indicate that the seawaters around East Asia are contaminated with flame retardants. This study demonstrates the presence of DP in fish marketed in Japan for the first time.
从日本市场购买的鱼类样本用于分析十氯酮（DP）（顺式、反式）、多溴二苯醚（PBDE）和六溴环十二烷（HBCD）（α、γ）。使用气相色谱-质谱法对 20 种鱼类进行 DP 和 PBDE 分析，使用液相色谱-串联质谱法进行 HBCD 分析。在 18 个样本中检测到 DP，ΣDP 浓度为<0.2-14.2pg g(-1)湿重。在 DP 异构体中，反式 DP 是本研究中观察到的主要残留物质。所有样本中均检测到 PBDE。ΣPBDE 浓度范围为 2.2 至 878pg g(-1)湿重。在东海和日本海附近捕获的鱼类中，检测到 DP、PBDE 和 HBCD 的浓度相对较高。这些结果表明东亚海域受到阻燃剂的污染。本研究首次证明 DP 存在于日本市场销售的鱼类中。
