Manganese (EC: 231-105-1; Cas: 7439-96-5)
Submitted in 2010, with no testing proposals, manganese has not undergone any aspect of the REACH evaluation process to date.
However, reviews to align the dossier with the ever-changing CLP adaptations has triggered Transformation Dissolution Protocol (TDp) testing for the purposes of environmental classification of fines/massives. The testing completed in by year end 2017 concluded that Mn fines at particle sizes <45 micron will be classified as Chronic cat 2 for the environment. A spontaneous update of the dossier is part of the 2018 work plan.
ECHA's soft letter dated 22 January 2018 sent to all Mn registrants http://consortium.manganese.org/news/article/four-manganese-substances-short-listed-by-the-echa-as-substances-of-potenti triggered a dossier update with a focus on reproductive toxicity endpoints. The lead dossier was updated to align with ECHA's request and submitted on February 16th, 2018
