Thursday, November 23, 2017 by

Chlorfenvinphos is an organophosphorus cholinesterase inhibitor that is used as an insecticide and an acaricide. It can be physically described as a colorless liquid with mild odor. It was widely used until all products that contain the chemical was banned in the United States in 1991. It was commonly used to control household pests such as flies, fleas, mice, ticks, lice, and mites on cattle and for blowfly, lice, ked, and itchmite on sheep.

In addition, it is used as a foliage insecticide for potatoes, rice, maize, and sugar cane and is used to control soil insects. Chlorfenvinphos has the molecular formula of C12H14Cl3O4P.

List of known side effects

There are a lot of side effects of chlorfenvinphos in humans, both acute and chronic health effects. Exposure to chlorfenvinphos can cause rapid, fatal organophosphate poisoning with headache, sweating, nausea, vomiting, diarrhea, loss of coordination, and death. If inhaled, the chemical may cause irritation in the lungs, which can also lead to coughing and/or shortness of breath. Inhalation may cause pupillary constriction, muscle cramp, and excessive salivation. It may also cause the vision to blur if eye contact occurs.

Moreover, higher exposures may result to severe shortness of breath and pulmonary edema, which is the build-up of fluid in the lungs. In addition to the list of acute health effects, it may also affect the heart, resulting to bradycardia, in which the heart beats slower, or arrhythmia wherein the heart beats irregularly. Long-term effects of the chemical are headache, confusion, loss of coordination, slurring of speech, convulsions, and unconsciousness. In addition, it may cause personality changes, depression, anxiety, or irritability. If the chemical is swallowed and inhaled, it can be fatal. Moreover, it can be toxic in contact with skin.

Chlorfenvinphos is highly toxic to mammals, birds, honeybees, and aquatic invertebrates, while it is moderately toxic to fish and earthworms.
