mg[Ag]/m3 as soluble silver compounds.
OSHA Table Z-1 Air Contaminant
Corrosive to the eyes, skin, and respiratory tract. Corrosive when ingested.
Contact with concentrated solutions will produce irritation, ulceration, and
discoloration of the skin; also causes severe irritation of the eyes. Ingestion
will produce violent abdominal pain and other gastroenteric symptoms. May
affect the blood; methemoglobin may be formed; the effects may be delayed.
Ingestion of nitrates has been implicated with cancer increase. Inhalation of
dust causes argyrosis. Chronic skin exposure will cause argyria, a blue-gray
discoloration of the eyes, skin, and brown fingernails. A mutagen.
