Many adverse effects of chronic exposure occur only above some threshold dose level, but others may not have identified thresholds for injury; differences in response will also occur within any exposed population 慢性接触的许多不良影响只有在高于某个临界剂量水平时才发生,而另一些影响可能没有明确的造成...

Related to threshold dose: Synergistic effectthresh·old (thrĕsh′ōld′, -hōld′) n. 1. A piece of wood or stone placed beneath a door; a doorsill. 2. Either end of an airport runway. 3. The place or point of beginning; the outset: on the threshold of a new era. 4. The po...
which states that for any chemical, the observed impact’s intensity is dose-dependent within a certain concentration range. This dose range’s lower limit, or threshold level, is established by the drug’s inherent potency.

The dose-response pattern of the data indicates that a threshold dose level may exist. Additionally, there is noticeable variation between the responses across the dose levels. With threshold estimation being critical, the assumed variability structure should adequately model the variation while not ...
