5 ENVIRONMENTAL HAZARD PROFILE

There is no environmental hazard assessment available for indium phosphide. The Annex XV

dossier (France 2009) did not consider environmental fate properties or hazards, since the dossier

was targeted at the identification of indium phosphide as a CMR substance. As indium phosphide is

not regulated under REACH, there is no information via ECHA databases available.

Additional desktop research did not reveal substantial information on environmental hazards. The

database of the PubChem of the US National Library of Medicine63 provided the following information

on environmental fate: “Monovalent and bivalent indium compounds tend to disproportionate into the

trivalent compounds and indium metal; the trivalent compounds are most stable. Due to the ionic

nature of indium salts, volatilization from soil surfaces will not be important.”

Against the lack of information, further aspects (identification of hazard potential, endpoints of

concern, potential for secondary poisoning and bioaccumulation, and guidance values [PNECs]) are

omitted in the dossier at hand.
