在制定接触标准时,往往假设在接触不到寿命的情况下,反应的概率取决于累积接触,即,暴露浓度和持续时间的乘积。在过去的二十年里,这个被称为哈伯定律的假设的普遍适用性开始受到质疑。本研究探讨了暴露浓度和暴露时间对胚胎发育的相互作用,在器官发生的一部分。胚胎暴露在全胚胎培养的各种温度持续时间的组合,并评价24小时后的发展变化。这项研究的具体目的是评估发育反应是否遵循哈伯定律,或者是否需要额外的暴露成分来模拟这种关系。目前的研究表明,发育中的胚胎对高温的反应,除了极少数例外,取决于累积暴露之外的额外暴露成分。对于本研究中测量的绝大多数参数,在相同的累积暴露量下,在较高温度下持续时间较短的影响概率大于在较低温度下持续时间较长的影响概率。因此,哈伯定律并没有充分描述我们的研究结果。
In developing exposure standards, an assumption is often made in the case of less-than-lifetime exposures that the probability of response depends on the cumulative exposure, i.e., the product of exposure concentration and duration. Over the last two decades, the general applicability of this assumption, referred to as Haber’s Law, has begun to be questioned. This study examined the interaction of exposure concentration and duration on embryonic development during a portion of organogenesis. Embryos were exposed in whole embryo culture to various temperature-duration combinations and evaluated for alterations in development 24 h later. The specific purpose of the study was to assess whether the developmental responses followed Haber’s Law, or whether an additional component of exposure was needed to model the relationship. The current study demonstrated that the response of the developing embryo to hyperthermia, with rare exception, was dependent on an additional component of exposure beyond the cumulative exposure. For the vast majority of the parameters measured in this study, the probability of an effect was greater at higher temperatures for short durations than at lower temperatures for long durations, given the same cumulative exposure. Thus, Haber’s Law did not adequately describe the results of our study.
