Summary: Parathion is an organophosphate used as an insecticide. It is a yellow liquid at room temperature. It has a solubility in water of 11 mg/L at 20 C and a density of 1.26 g/mL. Upon decomposition it produces gaseous carbon monoxide, nitrogen oxides, phosphorus, and sulfur. Parathion may penetrate leather and become corrosive towards plastics and rubber. It is classified by the EPA as a Hazardous Air Pollutant (HAPs). Koc values ranging from 314 to 15,860 predict low to no mobility within soil. The Koc values also indicate that adsorption to suspended solids within water will be high. Biodegradation from waters is a major process, but bioaccumulation within organisms is also expected to be high.
