Brilliant Blue FCF (C.I. 42090) was found to be a useful dye tracer to stain the flow paths of water in soil media. Being neutral or anionic, it is not strongly adsorbed by negatively charged soil constituents. The dye is used in food because its general toxicity is low. However, to stain the flow paths of water in soil, fairly large concentrations are required to ensure good visibility of the tracer. Therefore, toxic effects cannot be entirely excluded, and assessing the environmental risk is a necessity, especially when field research is conducted in an environmental context. A literature review was carried out to compile data on Brilliant Blue FCF toxicity. The literature suggests that there is no carcinogenicity or mutagenicity to rodents. Brilliant Blue FCF does not accumulate in plants or animals, but degrades slowly in the environment. From the toxicological point of view the dye can be considered as a suitable and environmentally acceptable tracer for studying solute transport in soil, especially in the field.

亮蓝 FCF 作为用于溶质运输研究的染料示踪剂 - 毒理学概述。

发现亮蓝 FCF (CI 42090) 是一种有用的染料示踪剂，可用于染色土壤介质中的水流路径。它是中性或阴离子性的，不会被带负电的土壤成分强烈吸附。该染料用于食品中，因为它的一般毒性较低。然而，为了染色土壤中水的流动路径，需要相当大的浓度以确保示踪剂的良好可见性。因此，不能完全排除毒性作用，评估环境风险是必要的，尤其是在环境背景下进行实地研究时。进行了文献综述以汇编关于亮蓝 FCF 毒性的数据。文献表明对啮齿动物没有致癌性或致突变性。亮蓝 FCF 不会在植物或动物体内蓄积，而是在环境中缓慢降解。
