South Carolina Paraquat Lawsuit
Paraquat, a weed killer used throughout South Carolina, is linked to Parkinson’s disease

Farmers, agricultural workers and groundskeepers who developed Parkinson’s disease after using the weed killer Paraquat might be eligible for compensation. A growing number of Paraquat lawsuits implicating the toxic weed killer for causing Parkinson’s disease have been filed throughout the country.
RPWB is a South Carolina-based law firm that is accepting the cases of farmers, farmhands, chemical applicators, groundskeepers, landscapers and others who were diagnosed with Parkinson’s disease or symptoms of Parkinson’s disease.
Paraquat is used extensively in the farming of wheat, corn, cotton, soybeans, tobacco and other crops. It is also used on golf courses and is used by landscapers.
Weed killers containing Paraquat have been on the U.S. market since 1964. The herbicide continues to be used to this day.
Paraquat is only sold to people with chemical applicator licenses in their respective states. It is also used by those who are unlicensed, but are working under someone else’s license. The types of clients we are able to represent are farmers, farmhands, chemical applicators, groundskeepers, golf course workers, landscapers and others who had repeated on-the-job exposure to Paraquat.
The people most at risk are those who actually mixed or applied herbicides containing Paraquat, including: Gramoxone, Ortho-Paraquat, Para-SHOT, Parazone, Quick-Quat, Firestorm and Helmqua.
Patients with Parkinson’s disease who had repeated exposure to Paraquat should consult with an experienced toxic exposure attorney without delay to see if their case can be included in national litigation against the manufacturers. RPWB is based in South Carolina with offices in Charleston, Mount Pleasant, Aiken and Columbia. We are a 2021 U.S. News Best Law Firm and are widely known for helping toxic exposure victims.

The Link between Paraquat and Parkinson’s Disease
A growing body of science points to Paraquat as a cause of Parkinson’s disease.
In his recent book, Dr. Bastiaan Bloem, a prominent neurologist who has published more than 700 scientific papers and chapters on Parkinson’s Disease, points to the tight link between exposure to herbicides such as paraquat — a weed killer — and the risk of developing Parkinson’s.
“These chemicals were introduced worldwide after World War II, and many are still used today on our fields,” he said. “For this reason, farmers are at a markedly increased risk of developing Parkinson’s. If you feed a mouse paraquat — which is banned in China but not the U.S. — it will kill the dopamine-producing cells in the brain. These chemicals are tremendously toxic to the brain and have even been detected in milk, in supermarkets.”
A recent study, published in the journal Toxicological Sciences in December 2020, confirmed that inhaling Paraquat gives it a direct pathway to the brain, where other studies have shown that it can impair dopamine receptors. Parkinson’s disease occurs when nerve cells in an area of the brain that controls movement become impaired or die. Normally, these neurons produce dopamine. When the neurons die or become impaired, they produce less dopamine, which causes the movement problems of Parkinson’s.
Common symptoms associated with Parkinson’s disease include shaking or tremors, stiffness and difficulty with walking, balance and coordination. As the disease progresses, it can affect a person’s ability to talk and chew food. It can be associated with memory loss and other behavioral issues.
In 2020, the EPA released new guidelines about the application of Paraquat seeking to reduce human exposure to the chemical, which is known to be toxic.

Who is at risk?
The use of Paraquat in the United States began in 1964, and continues to this day despite other governments such as China and the European Union already banning it. It is typically used in agricultural settings, but also is used on golf courses and in grounds maintenance at large facilities such as schools, parks, factories and other industrial sites. The people most impacted are those who mixed the chemicals or inhaled them during or just after application. This includes:
- Farmers
- Ranchers
- Farm-workers
- Aerial applicators
- Groundskeepers
- Landscapers
- Maintenance workers
Paraquat is used for weed control in many types of farming, including wide use by corn, soybean, tobacco and cotton farmers.
In October 2020, the EPA proposed new guidelines that would limit the use of Paraquat weed killers, including a prohibition of aerial application (except for cotton desiccation), requiring enclosed cabs and respirators, and creating a longer re-entry waiting period.
RPWB has a Strong Record with Toxic Exposure Cases
Attorneys at RPWB have been helping people harmed by dangerous products for more than 40 years.

We are in the leadership of national litigation against 3M for producing a toxic fire-fighting foam that is contaminating water systems throughout the United States. We have experience helping farmers as well. We recently helped corn farmers get compensation for financial losses they incurred when corn prices plummeted following China’s rejection of Syngenta GMO corn.
