答案（中文）
原则上，不同类型的物质（明确定义的物质 vs. UVCB）之间没有区别。我们的筛选算法适用于已注册的物质，无论其类型如何（单成分、多成分或 UVCB）。可以根据其各自的成分识别潜在问题。重要的是，UVCB 的成分信息应在 REACH 注册中妥善记录。
Answer (EN)
There is in principle no differentiation made between the different substance types (well-defined vs UVCB). Our screening algorithms are applied to registered substances regardless of the substance type (mono-constituent, multi-constituent or UVCB). A potential concern can be identified based on their individual constituents. It is important that the compositional information of UVCBs is properly documented in the REACH registrations.
