It acts on the nervous system of insects by inhibiting acetylcholinesterase. Chlorpyrifos is moderately toxic to humans, and exposure has been linked to neurological effects, persistent developmental disorders, and autoimmune disorders. Chlorpyrifos can be harmful if it is touched, inhaled, or eaten. Chlorpyrifos works by blocking an enzyme which controls messages that travel between nerve cells. When the enzyme is blocked, the nervous system can't send normal signals. Chlorpyrifos was first registered as an insecticide in 1965 and the United States Environmental Protection Agency (US EPA) re-registered it in 2006. The only legal indoor use for chlorpyrifos is in containers with treated baits. Crystalline in nature, chlorpyrifos is a form of organophosphate insecticide that is widely used in both agricultural and home settings. Organophosphates (sometimes abbreviated OP) are a common name for phosphoric acid esters. When this happens, headaches, dizziness, increased urination, loss of motion, and drooling can occur. If exposure has been excessive, convulsions, paralysis, and even death can result. Chlorpyrifos is classified as an endocrine disruptor, which can cause detrimental effects on the hormonal system as well. Effects on the central nervous system may include confusion, drowsiness, depression, difficulty concentrating, slurred speech, insomnia, nightmares, and a form of toxic psychosis resulting in bizarre behaviour (11) . Chlorpyrifos poses a risk of serious damage to eyes, and is irritating to skin (12) . Chlorpyrifos has an advantage over other products in that it is effective against a wide range of plant-eating insect pests. Production Chlorpyrifos (trade name Dursban, Lorsban and others) is primarily produced by the US multinational DowElanco. Chlorpyrifos (IUPAC name: O, O-diethyl O -3,5,6-trichloropyridin-2-yl phosphorothioate) is a crystalline organophosphate insecticide. It was introduced in 1965 by Dow Chemical Company and is known by many trade names (see table), including Dursban and Lorsban. Chlorpyrifos is moderately toxic to humans, and exposure has been linked to neurological effects, persistent developmental disorders, and autoimmune disorders. Dursban, also known as chlorpyrifos, is a highly toxic pesticide that was once widely used in the U.S. A nerve toxin, Dursban has been linked to birth defects, neurological injuries in children, and other ailments. It was used in homes, schools, daycare centers and many other places frequented by children.  Highlights. Chlorpyrifos is an insecticide which has been widely used in homes and on farms. Breathing or ingesting chlorpyrifos may result in a variety of nervous system effects, ranging from headaches, blurred vision, and salivation to seizures, coma, and death, depending on the amount and length of exposure. Chlorpyrifos is an insecticide that is a white crystal-like solid with a strong odor. It does not mix well with water, so it is usually mixed with oily liquids before it is applied to crops or animals. It may also be applied to crops in a capsule form. Chlorpyrifos has been widely used in homes and on farms. In the home, it is used to control cockroaches, fleas, and termites; it is also used in some pet flea and tick collars. On the farm, it is used to control ticks on cattle and as a spray to control crop pests. top Chlorpyrifos is one of about 100 organophosphate (OP) insecticides on the market today. It is used to kill insect pests by disrupting their nervous system. Chlorpyrifos has an advantage over other products in that it is effective against a wide range of plant-eating insect pests. Production Chlorpyrifos (trade name Dursban, Lorsban and others) is primarily produced by the US multinational DowElanco. Chlorpyrifos is an organophosphate insecticide. It is no longer registered for use inside homes except as bait in containers, but it is still used in agriculture, on golf courses, and to control public health pests such as fire ants. Chlorpyrifos blocks an enzyme that stops nerve cells from firing without stopping. If the enzyme is blocked, the nerves don't send normal signals, and the nervous system fails. Chlorpyrifos is used in agriculture, but it is no longer registered for residential us
