Chemical Properties
Lead arsenate is an odorless, heavy, white
powder, or crystals.
Potential Exposure
Used as an insecticide, herbicide, and
in manufacture of drugs; veterinary tapeworm medicine.
Incompatibilities: Violent reactions occur from contact
with oxidizers, chemically active metals; strong acids.
Acids and acid mists cause the release of arsine, a deadly
gas. Decomposes above 270C forming toxic fumes including arsenic and lead compounds
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately

Definition
ChEBI: Lead arsenate is an inorganic lead salt composed from lead(2+) and arsenate dianion. It was widely used in the United States in the 1950's as an insecticide to control pests in fruit orchards, specifically apples and cherries. It has a role as an insecticide, a plant growth regulator and a rodenticide. It contains a lead(2+) and an arsenate(2-).
