Paraquat (1-1´-dimetil-4-4-bipyridylium dichloride) is still widely used in Costa Rica as a contact herbicide and is marketed as a 20% aqueous solution (Gramoxone) .Paraquat poisoning carries a high mortality rate. Severe paraquat poisoning is characterized by multiple-organ involvement, mainly the lungs, kidneys, liver. The lung is a major target organ in paraquat poisoning, and respiratory failure from acute pulmonary fibrosis is the most common cause of death.

Keywords : intoxication; Paraquat; lung; lung fibrosis.
