化学的特性
Lead arsenate is an odorless, heavy, white
powder, or crystals.
使用
Trilead Diarsenate was an inorganic insecticide used primarily on fruit orchards in the early 1900s, but is now officially banned as an insecticide.
職業ばく露
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
輸送方法
