What is Paraquat?
Paraquat dichloride (commonly known as Paraquat) is one of the most widely used herbicides in the United States. It's primarily used to control weeds and grasses in agricultural settings, including on crops like corn, soybeans, cotton, and various fruits.
Unlike other herbicides available to consumers, Paraquat is restricted to licensed applicators due to its extreme toxicity. Even small amounts can be fatal if ingested, and long-term exposure has been scientifically linked to serious neurological conditions.
The Link Between Paraquat and Parkinson's Disease
Multiple peer-reviewed scientific studies have established a strong connection between Paraquat exposure and the development of Parkinson's disease. Research has shown that individuals exposed to Paraquat have a significantly elevated risk — in some studies, up to 2.5 times higher — of developing Parkinson's compared to those not exposed.
The manufacturers of Paraquat-based products have been aware of these risks for decades but failed to adequately warn users. Thousands of agricultural workers, farmers, and residents living near treated areas may have been unknowingly exposed. If you believe you have valid paraquat claims, a free case review can help determine your options.

Projected Paraquat Settlement Amounts
A global Paraquat settlement is being negotiated; payout amounts are still being finalized. Based on similar toxic exposure and Parkinson's cases, lawyers estimate potential settlement ranges by injury severity. Outcomes depend on the final settlement structure and your individual facts.
| Severity | Description | Estimated Range |
|---|---|---|
| High Severity | Advanced Parkinson's, significant disability, early onset, high medical needs | $100,000 – $500,000+ |
| Moderate Severity | Moderate symptoms, some work impact, ongoing treatment | $50,000 – $150,000 |
| Lower Severity | Mild to moderate Parkinson's, limited impact on daily life | $25,000 – $75,000 |
These are estimates only. No guarantee of recovery. Law firms work on contingency—you typically pay only if there is a recovery. Learn more about paraquat claims and settlement factors.
Evidence Linking Paraquat to Parkinson's Disease
Multiple peer-reviewed studies have established a connection between Paraquat exposure and an increased risk of Parkinson's disease. Researchers have identified mechanisms by which Paraquat may damage dopamine-producing neurons in the brain.
Agricultural Health Study (AHS)
The NIH-funded Agricultural Health Study followed tens of thousands of farmers and pesticide applicators. Analyses found that individuals who used Paraquat had a significantly elevated risk of developing Parkinson's disease compared to those who did not—with risk estimates ranging from about 1.5x to 2.5x higher depending on exposure levels.
Key finding: Up to 2.5x increased risk with Paraquat use
UCLA / Environmental Health Studies
UCLA researchers and others have published studies showing that Paraquat exposure is associated with oxidative stress and damage to dopaminergic neurons—the same cells affected in Parkinson's disease. Combined exposure to Paraquat and certain other pesticides may further increase risk.
Key finding: Biological plausibility for Paraquat-induced Parkinson's
Meta-Analyses and Systematic Reviews
Meta-analyses pooling data from multiple studies have consistently found an association between Paraquat exposure and Parkinson's disease risk. These analyses strengthen the scientific basis for litigation claims that manufacturers knew or should have known about the risks.
Key finding: Consistent association across studies
