Other deicing chemicals include magnesium chloride, potassium acetate, calcium chloride, calcium magnesium acetate, and potassium chloride (these are described below). Abrasives such as sand are often used in conjunction with deicing chemicals to provide traction for vehicles, particularly on corners, intersections, and steep grades. However, when sand is overused, it often ends up in the environment, either as dust particles that contribute to air pollution or in runoff to streams and rivers.
Chemical castration is castration via drugs, whether to reduce libido and sexual activity, to treat cancer, or otherwise. Unlike surgical castration, where the gonads are removed through an incision in the body, chemical castration does not remove organs, nor is it a form of sterilization.n 1966, John Money became the first American to employ chemical castration by prescribing medroxyprogesterone acetate (MPA, the base ingredient now used in Depo Provera) as a treatment for a patient dealing with pedophilic urges. The drug has thereafter become a mainstay of chemical castration in America.
