What is Paraquat?
Paraquat Dichloride a/k/a Paraquat is a quaternary ammonium compound or Quat. Quats are best known as disinfectants, however, Paraquat is used as a broad-spectrum, fast-acting contact herbicide. It is sold in the United States under the brand name Gramoxone.
Paraquat is registered for use in both agricultural and non-agricultural settings. In the non-agricultural setting, it is a weed killer. In the agricultural setting, Paraquat is used to both control weeds and as a post-harvest desiccant.
A desiccant is a chemical used to “dry up” or kill the plant so that the crop is easier to harvest and process. It is applied as a direct spray and only kills the leaves that come in direct contact with the compound. Paraquat is inactivated when it lands on the soil. Paraquat is not registered for residential use. Thus, it is only permitted to be applied under the supervision of a licensed applicator.
What Injuries Are Allegedly Caused by Paraquat Exposure?
Parkinson’s Disease is the most serious injury alleged to be caused by Paraquat exposure. A number of studies going back several decades have linked Paraquat to Parkinson’s Disease.
Other injuries may depend upon the degree of exposure. Talk to a Paraquat exposure lawyer to determine whether your injuries are linked to Paraquat exposure.
High-Level Acute Exposure vs Low-Level Acute Exposure
Paraquat is characterized as having high acute inhalation toxicity, moderate acute oral toxicity, and slight acute dermal toxicity according to research done by the National Toxicology Program of the U.S. Dept. of Health & Human Services. High-level acute exposure is associated with pulmonary toxicity since Paraquat has been shown to accumulate in the lung tissues. Low-level ongoing exposure has been associated with damage to the lungs and central nervous system. Talk to a paraquat exposure attorney to learn more.
What is Parkinson’s Disease?
Parkinson’s Disease is a non-life-threatening neurodegenerative disease that affects different people and their muscle movements to different degrees. It can have very serious symptoms. The most common symptoms of Parkinson’s Disease include:
- Tremors, most commonly in the hands. (Many are described as pill-rolling tremors because the thumb and forefinger rub together as if rolling a tiny pill between them.)
- Slowness of movement
- Limb rigidity
- Gait and balance problems
- Monotone speech changes or slurring
- Writing changes
- Loss of automatic movements.
Parkinson’s tends to be defined in stages 1-5 for its degree of severity. In the latter stage, the patient is often confined to a wheelchair.
How Do People Get Exposed to Paraquat?
Paraquat can get into your system from contact with your skin, through inhalation, and from contact with your eyes or mouth. There are three main ways in which paraquat exposure occurs: exposure during the manufacturing process, exposure during the application process, and incidental exposure.
- Manufacturing process exposure. Obviously, there is a risk of exposure during the manufacturing and application processes of Paraquat. If the chemical is inhaled by workers in or around the area or it is splashed on their eyes, mouth, or skin, exposure occurs.
- Application process exposure. Workers on farms applying Paraquat without proper gear face potential exposure from inhalation or contact.
- Incidental Exposure. Even though Paraquat is not registered for residential use, inhalation exposure can occur for people who live on, or near farms that use Paraquat.
How Long Have the Manufacturers Known of the Dangers of Paraquat?
Internal documents uncovered by The Guardian suggest that the manufacturer Syngenta’s “insiders feared they could face legal liability for long-term, chronic effects of paraquat as long ago as 1975.” Studies specifically linking Paraquat exposure and accumulation in brain tissue and neurological tissue damage consistent with the etiology of Parkinson’s disease have existed as far back as 2002. McCormack AL, Thiruchelvam M, Manning-Bog AB, Thiffault C, Langston JW, Cory-Slechta DA, Di Monte DA. 2002. Environmental risk factors and Parkinson’s disease: selective degeneration of nigral dopaminergic neurons caused by the herbicide paraquat. Neurobiol Dis 10(2): 119-127. Research published in 2007 in the American Journal of Epidemiology suggested that the use of Paraquat within 1600 feet of a home increased the residents’ risk of developing Parkinson’s Disease by 75%.
Who Are the Defendants in the Paraquat Lawsuits?
The primary defendants include Syngenta Crop Protection, LLC., Syngenta AG, Growmark, and Chevron U.S.A., Inc. Syngenta Crop Protection, LLC., Syngenta AG, and Growmark, are the manufacturers of Paraquat and are headquartered in Basel, Switzerland. U.S.A., Inc. distributed and sold Paraquat under the Brand name Gramoxone in the United States pursuant to an agreement with Imperial Chemical Industries (ICI)—a predecessor to the Syngenta companies.
The lawsuits accuse these defendants of making, marketing, and selling a product that they knew caused Parkinson’s disease and of concealing the risks of the herbicide and hiding evidence of its dangers from government safety agencies so as to be able to sell the product in the United States for the past 50+ years.
What Crops Were Treated With Paraquat?
Paraquat obtained EPA approval for use on over 100 different crops grown in the United States. These approvals extend to commonly produced crops such as coffee, cotton, maize, potatoes, rice, soybeans, sugar cane, tea, wheat, and several fruits.
Free Consultation
You should obtain a free consultation with a Paraquat exposure lawyer if you worked with or around Gramoxone (Paraquat) or live near a farm that you suspect may have applied Paraquat and you developed Parkinson’s Disease. You may be subject to a short statute of limitations stemming from the date of your diagnosis and/or when you knew or should have known of the relation between Paraquat and Parkinson’s Disease. Thus, your time to file a claim may be very limited.
