Does ECHA use mode of action information for forming groups?

在人工筛选层面，分组主要基于化学原理，对具体作用机制的考虑有限。这部分是由于复杂性，也因为在人工筛选之前，我们不确定所有危害都已识别。如有需要且MSCAs提出要求，可在人工筛选过程中进行额外分组。在这种情况下，我们将考虑关于可能作用机制的现有信息，以设计一种反映这些知识的分组方法。

At the level of manual screening, grouping is mostly chemistry based with limited consideration on the specific mode of action. This is partially due to complexity but also because prior to manual screening we are not certain that all hazards have been identified. Additional grouping may be carried during manual screening if needed and requested by the MSCAs, in which case available information on likely mode of action will be taken into account to design a grouping approach that reflects this knowledge.
