In order to establish an efficient strategy of research on dioxin exposure evaluation in incinerator workers, dioxin concentrations in serum and deposited dust were measured in thirteen incineration plants. The findings are as follows.1) Dioxin concentrations in the deposited dust samples were 0.54 to 33 ng TEQ/g, which were about 1,000 times general soil.2) In ten of the 13 incineration plants, serum HpCDF concentration was significantly higher for incinerator workers than for controls. The increase was considered to be caused by occupational dioxin intake.3) This study found positive correlation between exposure index calculated from dust dioxin concentration and serum HpCDF concentration in the 12 incineration plants except for one plant where large-scale improvement of the equipment was conducted. Consequently, by calculating the exposure index, it is possible to classify incineration plant as to need medical examination with measurement of blood dioxin concentration or not.

为了建立有效的垃圾焚烧厂工人二恶英暴露评价方法，对13个垃圾焚烧厂工人血清和沉降尘中二恶英浓度进行了测定。结果表明：（1）垃圾焚烧厂粉尘中二恶英的浓度为0.54 ~ 33 ng TEQ/g，约为一般土壤的1,000倍;（2）13个焚烧厂中有10个焚烧厂工人血清中HpCDF浓度显著高于对照组。3）本研究发现，在12个焚烧厂中，除一个进行了大规模设备改进的焚烧厂外，根据粉尘二恶英浓度计算的暴露指数与血清HpCDF浓度呈正相关。因此，通过计算暴露指数，可以将焚烧厂分类为需要进行血液二恶英浓度测量的医疗检查或不需要。
