Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information - General Population

The inhalation toxicity of manganese bis(dihydrogen phosphate) is influenced by the Mn2+ cation and as such the material is considered to be classified via the inhalation route as STOT RE2 (target organ brain) in accordance with Regulation (EC) No. 1272/2008 (EU CLP) and on the basis of neurological symptoms (neurotoxicity) observed after inhalation of manganese. Neurotoxicity is considered to be the leading health effect and as such an IOELV has been proposed and adopted by the European Commission (1). This relates primarily to cumulative exposures however the authors state that as the proposed values are not based on one single study but on a database of available data the values proposed are acceptable for use in the risk mitigation of both cumulative and peak exposures.

 

The values are as follows:

- Inhalable IOELV: 0.2 mg/m3

- respirable IOELV: 0.05 mg/m3

It is recommended that both values should be observed conjointly.
