我们测量了生活在芬兰南部的 420 名普通芬兰人的脂肪组织中多氯二苯并-对-二恶英、二苯并呋喃 (PCDD/F) 和多氯联苯 (PCB) 的浓度。 WHOPCDD/F-TEQ 和 WHOPCB-TEQ 的平均（中位）浓度分别为 29.0 (24.1) 和 20.7 (16.7) pgg(-1) 脂肪。浓度与年龄明显相关。将浓度表示为受试者年龄的函数表明，芬兰人的暴露量在过去 30 年中有所下降。从波罗的海沿岸到芬兰内陆地区，浓度呈下降趋势，据评估，这是由于食用波罗的海鱼类，特别是波罗的海鲱鱼造成的。自然对数 WHOPCDD/F-TEQ、自然对数 WHOPCB-TEQ 和自然对数 WHOtotal-TEQ 的线性回归模型分别解释了 70%、69% 和 72% 的变异性。年龄、哺乳期、居住地和鱼类消费频率是模型中的重要预测因素。 (c) 2005 Elsevier Ltd. 保留所有权利。
We measured adipose tissue concentrations of polychlorinated dibenzo-p-dioxins, dibenzofurans (PCDD/Fs), and polychlorinated biphenyls (PCBs) in 420 general Finns living in southern Finland. The mean (median) concentrations of WHOPCDD/F-TEQ and WHOPCB-TEQ were 29.0 (24.1) and 20.7 (16.7) pgg(-1) fat, respectively. The concentrations clearly correlated with age. Expressing the concentrations as a function of subject's ages revealed that the exposure of Finns has declined over the last 30 years. A downward gradient was found in the concentrations from the Baltic Sea coast to inland areas in Finland, and this was assessed to be due to consumption of the Baltic Sea fish, especially Baltic herring. Linear regression models for natural logarithm WHOPCDD/F-TEQ, natural logarithm WHOPCB-TEQ, and natural logarithm WHOtotal-TEQ, explained 70%, 69%, and 72% of the variability, respectively. Age, lactation, place of residence, and fish consumption frequencies were significant predictors in the models. (c) 2005 Elsevier Ltd. All rights reserved.
