Summary: Endrin is an organochloride compound formerly used as an insecticide, rodenticide, and piscicide. It has also been used to control bird populations. It was banned from use as a pesticide in the United States in 1986. The compound is soluble in water up to 0.25 mg/L at 25 C and has a density of 1.7 g/mL. It has a biological half-life in fish of 44.16 days. Endrin will be immobile in soil based on a Koc value of 11,420. Endrin is persistent in soil with a half-life of 4 to 8 years. Hydrolysis, biodegradation, and volatilization are expected to be very slow processes in water. Bioaccumulation is expected to be very high in organisms.
