| Comments |
Silver nitrate, used in burn therapy, is a reported inducer of methemoglobinemia. [ATSDR Case Studies, # 16] In the past, acute renal failure was reported in film developers after exposure to soluble silver compounds. [Rosenstock, p. 574] Argria is the local or generalized impregnation of the mucous membranes, skin and eyes with silver. |

| Excerpts from Documentation for IDLHs |
Basis for revised IDLH: No inhalation toxicity data are available on which to base an IDLH for silver (metal dust and soluble compounds). Therefore, the revised IDLH for silver (metal dust and soluble compounds) is 10 mg Ag/m3 based on acute oral toxicity data in humans [Arena 1970] and animals [Flury and Zernik 1935]. |
