メタンアルソン酸カルシウム（２：１） 化学特性,用途語,生産方法
化学的特性
Colorless liquid. Odorless.
安全性プロファイル
Moderately toxic by
intraperitoneal and possibly other routes.
Arsenic compounds are considered to be
poisons. An herbicide. When heated to
decomposition it emits toxic fumes of As.

不和合性
Keep this material away from bases, heavy metal salts, strong oxidizers; alkaline materials. Contact
with reducing agents may release toxic arsine gas
廃棄物の処理
Do not discharge into drains
or sewers. Dispose of waste material as hazardous waste
using a licensed disposal contractor to an approved landfill.
Consult with environmental regulatory agencies for guidance on acceptable disposal practices. If allowed,
Incineration with effluent gas scrubbing is recommended.
In accordance with 40CFR165, follow recommendations for
the disposal of pesticides and pesticide containers.
Noncombustible containers should be crushed and buried
under more than 40 cm of soil. Must be disposed properly
by following package label directions or by contacting your
local or federal environmental control agency, or by contacting your regional EPA office. Chemical Treatability of
