垃圾焚烧、商业多氯联苯产品和两种农用化学品PCP和CNP被认为是日本环境中二恶英的四个主要来源。在本研究中，2，3，4，7，8-PeCDF，2，3，3‘，4，4’-五氯苯(#105)，1，2，3，4，6，7，8-HpCDD和1，2，3，7，8-PeCDD分别被选为上述四种二恶英来源的指示异构体。提出了利用四种指示性异构体的浓度来估算四种来源的TEQ的公式，并与以前的报告进行了比较。这些公式适用于环境空气、土壤、河流沉积物和河水等环境样品。估计的总TEQ与观察到的总TEQ大致相等。
Waste combustion, commercial PCB products, and two agrochemicals, PCP and CNP, are considered as four major sources of dioxins in the environment of Japan. In this study, 2,3,4,7,8-PeCDF, 2,3,3',4,4'-PeCB (#105), 1,2,3,4,6,7,8-HpCDD, and 1,2,3,7,8-PeCDD were selected as respective indicator isomers for the above-mentioned four dioxin sources. Formulas to estimate the respective TEQs originated from the four sources using the concentrations of the four indicator isomers were proposed, and were validated by comparison with the previous reports. The formulas were applied to environmental samples such as ambient air, soil, river sediment, and river water. The estimated total TEQ was approximately equal to the observed total TEQ.
