我应该如何报告具有可变化学计量的无机物质？

How should I report my inorganic substance with variable stoichiometry?

原则上，化学计量学可变的无机物质由于分子式的可变性而被认定为无机UVCB。您应该按如下方式识别此类物质：在IUCLID第1.1节中，在“物质类型”字段下选择“无机”作为来源，并选择“UVCB”作为物质类型。在分子式字段下报告化学计量学的可变性（例如MxGyO2，x=ab，y=cd）。如果IUCLID档案第1.2节仅报告了一个组成块，请在“偏差理由”字段中提供报告UVCB物质组成中单个成分（预计具有可变的复杂组成）的理由。有效理由的示例可以是：“该物质由于元素水平的变化而成为UVCB，因此这些变化不能通过报告不同的成分来表示，而只能以可变的分子式形式表示。”

Inorganic substances with variable stoichiometry are, in principle, identified as inorganic UVCBs due to the variability of the molecular formula. You should identify such a substance as follows: In IUCLID section 1.1, select "Inorganic" as the origin under the "Type of Substance" field, and select "UVCB" as the substance type.Report the variability in the stoichiometry under the molecular formula field (e.g. MxGyO2, x=a-b, y=c-d). In case only one constituent block is reported in section 1.2 of the IUCLID dossier, provide a justification for reporting a single constituent in the composition of a UVCB substance (expected to have a variable complex composition) in the “justification for deviations” field. An example of a valid justification could be: “The substance is a UVCB due to variations at the elemental level and these variations cannot therefore be represented by reporting different constituents but only in the form of a variable molecular formula.”
