DHA reduces toxicity caused by chlorpyrifos


Chlorpyrifos is a organophosphate insecticide that kills mites and ticks, which has been widely used since 1965 in homes and on farms. In agriculture, to control foliage and soil-borne insect pests (among other crops: corn, soybeans, fruit trees, Brussels sprouts, cranberries, broccoli, and cauliflower). It is used also in golf courses, turf, and green houses; in the home, it is used to control cockroaches, fleas, and termites; and it is also used in some pet flea and tick collars.

Breathing or ingesting chlorpyrifos may produce diverse nervous system effects, from headaches, blurred vision, lacrimation, nausea, dizziness, confusion, and excessive salivation to loss of bowel control, severe muscle tremors, seizures, loss of consciousness (coma), respiratory paralysis or death, depending on the amount and length of exposure. Furthermore, this insecticide is classified as a possible human carcinogen. People who works with chlorpyrifos (handling and applying it) must wear personal protective equipment (chemical resistant gloves, coveralls, respirators), and should avoid coming into treated fields for 24 hours up to five days.

DHA has a preventive effect on toxicity caused by chlorpyrifos, reducing it. This information is particularly useful if we think we are exposed to this insecticide.
