TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin) in the edible portion of fish and shellfish from various U.S. waterways has been monitored since 1979. Analytical results for the period 1979-1994 are reported. Extracts obtained after column chromatographic and liquid chromatographic cleanup were examined by electron capture detection-gas chromatography (GC), and final quantitation and confirmation were performed by GC/mass spectrometry with multiple ion detection. Analyses of 1623 test samples indicated that TCDD residues in fish and shellfish were not widespread but rather were localized in areas near waste sites, chlorophenol manufacturers, and pulp and paper mills. Analytical results indicated that levels in aquatic species from these sites have been declining steadily. No TCDD (limit of detection and confirmation, 1-2 ppt) has been found in recent years in aquatic species from most Atlantic, Pacific, and Gulf of Mexico sites and Great Lakes other than Lake Ontario and Saginaw Bay (Lake Huron).
自1979年以来，美国各水道鱼类和贝类可食用部分中的2,3,7,8 - 四氯二苯并 - 对 - 二恶英（TCDD）一直受到监测。报告了1979年至1994年期间的分析结果。通过柱色谱和液相色谱净化后获得的提取物，采用电子捕获检测 - 气相色谱（GC）进行检测，最终定量和确证通过具有多离子检测功能的GC/质谱法进行。对1623个测试样本的分析表明，鱼类和贝类中的TCDD残留并不普遍，而是局限于废物处理场、氯酚制造商以及纸浆和造纸厂附近的区域。分析结果表明，来自这些地点的水生生物体内的TCDD含量一直在稳步下降。近年来，除安大略湖和萨吉诺湾（休伦湖）外，在大多数大西洋、太平洋、墨西哥湾以及五大湖的水生生物中均未检测到TCDD（检测和确证限为1 - 2 ppt）。
