Abstract

In 2022, the European Chemicals Agency (ECHA) made a statement concluding that iodine is an endocrine disruptor (ED). "We stress the fact that the ECHA opinion ECHA/BPC/357/2022 is based on their misguidedly zooming in on exclusively the biocidal products (e.g., hand disinfectants, disinfection of animals’ teats/udder, embalming fluids before cremation, etc.) that contain molecular iodine (I2), entirely neglecting [see the 2013 ECHA Regulation (EU) n°528/2012 describing iodine as being of “great importance for human health”. Clearly, the current sweeping and erroneous classification of “iodine” as an endocrine disruptor is ill-advised. We moreover call upon the scientific and medical community at large to use the accurate scientific nomenclature, i.e., iodide or iodate instead of “iodine” when referring to iodized salts and food prepared there with. Drugs, diagnostic agents, and synthetic chemicals containing the element iodine in the form of covalent bonds must be correctly labelled ‘’iodinated’’, if possible, using each time their distinctive and accurate chemical or pharmacological name.
