“Paraquat is one of the pesticides most frequently used to commit suicide. There is no antidote for paraquat. The mortality rate for paraquat suicide attempts is comparatively high, at 42 to 80 per cent,” read the report. The number of suicides in the world using paraquat is estimated to be several tens of thousands per year, it added. The purpose of this report is to describe cases of paraquat poisoning recorded at the Poison Control Center in Marseille over the 9-year period starting .
Paraquat poisoning remains a public health concern in Malaysia due to its high mortality and significant morbidity. However, there is limited publication of local data in regards to paraquat poisoning, particularly since the lifting of the ban in This study aims to describe the demographic characteristics, clinical features and outcomes. Paraquat is in the news because of toxicity concerns, discussed in an article in the December 20th New York Times, so this is a good time to examine what paraquat does and doesn't do. Ideally, a pesticide or herbicide (and "cide," really) should target the pest by disrupting a process that does not have a human counterpart.
The records say that, between September and December , as many as 32 persons were admitted with Paraquat poisoning to VIMSAR. Of them, 31 did not survive, and one patient left against medical. Paraquat is a Restricted Use Pesticide (RUP) and is banned for use in several Scandinavian countries. Restricted Use Pesticides may be purchased and used only by certified applicators. TOXICOLOGICAL EFFECTS ACUTE TOXICITY Paraquat is highly toxic to animals by all routes of exposure, and is labeled with a DANGER-POISON signal word.

Paraquat poisoning is a fast process, and symptoms develop quickly. Immediately after ingesting or inhaling a toxic amount of paraquat, an individual is. Paraquat garden items poisoning in dogs occurs when dogs ingest paraquat, a powerful ingredient that is included in a variety of herbicides and pesticides.
This substance is primarily used for agricultural needs, as well as for weed and grass control. • Paraquat is an organic acid that is used as an herbicide.
It kills green plant tissue on contact. • When sprayed on plants, paraquat is tasteless and odorless and invisible. In other words, you wouldn’t be able to tell if the weed you were smoking had been sprayed with paraquat.
Paraquat (dipyridylium) is a highly toxic weed killer (herbicide). In the past, the United States encouraged Mexico to use it to destroy marijuana plants.
Later, research showed this herbicide was dangerous to workers who applied it to the plants. This article discusses the health problems that can occur from swallowing or breathing in paraquat.
Paraquat poisoning typically occurs from direct overexposure to the chemical. Most commonly, the poisoning happens after the chemical is ingested, though inhaling the chemical and having it exposed to the skin can be just as poisonous and detrimental to a person's health. Paraquat, a commonly used herbicide, is known to cause myopathy in humans examined at both biopsy and necropsy.
A few cases of paraquat poisoning and myopathy are described here in brief. Dinis-Oliveira et al. () reviewed the toxicity of this herbicide in detail.
Discussion. Paraquat is a commonly used non-selective herbicide ().According to the International Program for Chemical Safety Classification System of Pesticides by the World Health Organization (WHO), paraquat is classified as ‘moderately hazardous’ (WHO class II) ().The herbicide industry claims that paraquat is safe if handled as instructed, yet paraquat Cited by: 6.
Paraquat Poisoning: Mechanisms, Prevention, Treatment (DRUG AND CHEMICAL TOXICOLOGY) 1st Edition by Chantal Bismuth (Author), Price: $ Paraquat. Paraquat, a commonly used herbicide, is known to cause myopathy in humans examined at both biopsy and necropsy. A few cases of paraquat poisoning and myopathy are described here in brief.
Recently, Dinis-Oliveira et al. () reviewed the toxicity of this herbicide in detail. Koppel et al. Paraquat poisoning is also possible after skin exposure. Poisoning is more likely to occur if the skin exposure lasts for a long time, involves a concentrated version of paraquat, or occurs through skin that is not intact (skin that has sores, cuts, or a severe rash).
If it is inhaled, paraquat could cause poisoning leading to lung damage. Paraquat (PQ) (1,1-dimethylbipyridium dichloride; gramoxon), is an herbicide that is commonly used for suicide attempts. PQ has been used for the past three decades in Korea, with an estimated 2, toxic ingestions annually and an associated % mortality [ 2 ].Cited by: Paraquat dichloride, commonly referred to as “paraquat,” is an herbicide registered in the United States since to control weeds in many agricultural and non-agricultural use sites.
It is also applied as a pre-harvest desiccant on some crops including cotton. Serum paraquat- nomograms –correlate serum paraquat concentration with mortality risk The proudfoot nomogram, best cut off for the Severity in Paraquat Poisoning(Sipp) Sipp score-paraquat concentration(mg/dl) x time since poisoning(hrs) The clinical features of paraquat poisoning are well recognised.
However 2 observations are made from this study: 1) In any case of unknown poisoning, paraquat must be suspected when the patient has painful mouth ulcers, acute renal failure and liver dysfunction.
2) Dyspnoea is an ominous sign followed by a rapidly progressive downhill course. Paraquat is a bipyridyl compound with no known chronic toxicity or teratogenicity. It is poorly absorbed when inhaled, but causes severe illness when ingested orally, death usually occurring within 2 days of ingestion of 50 mg/kg.
At lower doses death may be delayed for several weeks. The toxic compound accumulates in lung tissue where free radicals are formed, lipid Cited by: Bismuth C, Garnier R, Baud FJ, Muszynski J, Keyes C. Paraquat poisoning: an overview of the current status.

DIQUAT Toxicology Diquat poisoning is less common than paraquat poisoning, thus the human reports and animal experimental data for diquat poisoning are less extensive than for para-quat.
Systemically absorbed diquat is not selectively concentrated in lung tissue, as is paraquat, and pulmonary injury by diquat is less prominent.
Paraquat poisoning, characterized by multi organ failure and pulmonary fibrosis with respiratory failure, is widely reported worldwide. However, the data from our country is scanty.Paraquat is a fast acting, potent, and non-selective contact herbicide.
Paraquat poisoning, resulting in serious damage to various organs, may be caused by ingestion of just one teaspoon of paraquat. Paraquat poisoning is frequently fatal.

There is as yet no successful treatment for this form of poisoning and efforts to diminish its lethal effect continue to be only .
