To examine the levels of PCDD/DFs pollution in environmental samples in the vicinity of various incinerators, the levels of PCDD/DFs in air and soil samples collected near 17 incinerators and stack emission gases were investigated between 2003 and 2006. A total of 434 soil, 28 stack emission gas, and 38 air samples were analyzed for their PCDD/DFs concentrations. The PCDD/DFs concentrations in the flue gas samples ranged from 0.02 to 16.41 ng I-TEQ/Sm(3), with an arithmetical mean value of 3.13 ng I-TEQ/Sm(3). The PCDD/DFs concentrations in the air samples ranged from 0.032 to 0.965 pg I-TEQ/Sm(3). The soil samples contained between N.D. and 153.23 pg I-TEQ/g-dry, with an average of 7.36 pg I-TEQ/g-dry. These levels were generally consistent with or lower than many previous studies. The average PCDD/DFs levels in the soil samples decrease with increasing distance from the incinerator. From the PCDD/DFs level gradient from each plant, a distance of 500 m is suggested as being under the influence of an incinerator.
为检测各类焚烧炉附近环境样品中多氯二苯并对二噁英/多氯二苯并呋喃（PCDD/DFs）的污染水平，于2003年至2006年期间，对17座焚烧炉附近采集的空气和土壤样品以及烟囱排放气体中的PCDD/DFs水平进行了调查。共分析了434份土壤样品、28份烟囱排放气体样品和38份空气样品中的PCDD/DFs浓度。烟道气样品中PCDD/DFs的浓度范围为0.02至16.41 ng I-TEQ/Sm(3)，算术平均值为3.13 ng I-TEQ/Sm(3)。空气样品中PCDD/DFs的浓度范围为0.032至0.965 pg I-TEQ/Sm(3)。土壤样品中PCDD/DFs的含量在未检出至153.23 pg I-TEQ/g干重之间，平均为7.36 pg I-TEQ/g干重。这些水平总体上与之前的许多研究一致或更低。土壤样品中PCDD/DFs的平均水平随与焚烧炉距离的增加而降低。根据各工厂的PCDD/DFs水平梯度，建议500米的距离处于焚烧炉的影响范围内。
