Chemical dangers
Decomposes on heating. This produces toxic fumes of arsenic and lead. Reacts with oxidants. Reacts with strong acids. This produces toxic gas (arsine - see ICSC 0222).

Formula: As₂O₄Pb / Pb(AsO₂)₂
Molecular mass: 421.0
Density: 5.85 g/cm³
Solubility in water: none

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion. Effects of short-term exposure The substance is irritating to the eyes and respiratory tract. Ingestion could cause effects on the gastrointestinal tract. This may result in severe gastroenteritis, loss of fluids and electrolytes, cardiac disorders and shock. Exposure far above the OEL could cause death. The effects may be delayed. Medical observation is indicated.	Inhalation risk A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. Effects of long-term or repeated exposure The substance may have effects on the skin, mucous membranes, bone marrow, blood, central nervous system, peripheral nervous system and liver. This may result in pigmentation disorders, perforation of the nasal septum, anaemia, nervous system impairment and liver impairment. This substance is carcinogenic to humans. Causes toxicity to human reproduction or development.
