According to Column 2 of REACH Annex VIII (standard information requirements for substances manufactured or imported in quantities of 10 tonnes per year or more) of Regulation (EC) No 1907/2006 and ECHA Guidance on information requirements and chemical safety assessment, STP toxicity testing (activated sludge respiratory inhibition testing) does not need to be conducted if there is no emission to a sewage treatment plant or there are mitigating factors, indicating that microbial toxicity is unlikely to occur, for instance the substance is highly insoluble in water (limitation of exposure). Hexagonal boron nitride is an inorganic crystalline solid covalent nitride with a high chemical inertness (1). It is inert to concentrated and dilute hydrochloric and nitric acid, aqua regia, and alkali solutions at the boiling temperature and it is practically insoluble in water (see section 4.8 of the IUCLID dossier).
