A total of 175 samples, composed of 35 different foodstuffs, were obtained from retail markets in Korea and analyzed to investigate the contamination status and dietary intake of Dechlorane compounds. The concentrations of Dechlorane Plus (DP), mirex, Dechlorane (Dec) 602 and 603 ranged from ND to 169.85 pg/g wet weight (ww), 107.30 pg/g ww, 20.81 pg/g ww, 0.41 pg/g ww, respectively, while Dechlorane (Dec) 604 was not detected in any samples. Strong correlations between anti- and syn-DP and between mirex and Dec 602 were observed. The average anti-isomer fractional abundance (fanti) was 0.78±0.11 which was larger than the technical DP value (fanti=0.75). The estimated dietary daily intake of DP, 11.2×10(3) pg/day, was one to three orders of magnitude higher than other Dechloranes. Grain was the most contributed food group to dietary daily intake of DP for Korean population.
共采集了 175 个样本，这些样本来自韩国的零售市场，由 35 种不同的食品组成，用于分析调查 Dechlorane 化合物的污染状况和膳食摄入量。检测到的 Dechlorane Plus（DP）、灭蚁灵、Dec 602 和 603 的浓度范围分别为 ND 至 169.85pg/g 湿重（ww）、107.30pg/g ww、20.81pg/g ww、0.41pg/g ww，而 Dec 604 则未在任何样本中检出。反式和顺式 DP 之间以及灭蚁灵和 Dec 602 之间存在很强的相关性。反式异构体分数丰度（fanti）的平均值为 0.78±0.11，大于技术 DP 值（fanti=0.75）。估算的 DP 膳食日摄入量为 11.2×10(3)pg/天，比其他 Dechloranes 高 1 到 3 个数量级。谷物是韩国人群 DP 膳食日摄入量的主要贡献食物组。
