- Brief Review
- Paraquat (PQ; N,N'-dimethyl-4,4'-bipyridinium dichloride) is a highly toxic organic material that was previously used as an herbicide. Paraquat has toxic effects on the lungs, liver, and kidneys. Death from paraquat poisoning is primarily caused by progressive pulmonary damage and respiratory failure. In the past, paraquat intoxication was a serious public health problem, with an estimated annual incidence of 2000 toxic ingestions associated with a mortality rate of 60%
