The Top 3 Places Paraquat Is Used in Los Angeles—and Who Is Exposed

Paraquat is one of the most toxic herbicides ever created. It is so lethal that in the United States, it is a “restricted use” chemical, meaning only licensed applicators are legally allowed to handle it. Despite being banned in over 50 countries, it remains in use across California, including in and around Los Angeles County. The chemical is highly effective at killing weeds, but its devastating cost is becoming tragically clear. Scientific research has established a strong link between Paraquat exposure and the development of Parkinson’s disease, an incurable and progressive neurological disorder.

For residents of Los Angeles, the danger is closer than you might think. You do not have to be a licensed applicator to suffer the consequences of this poison. At Walch Law, we are dedicated to helping victims of toxic exposure understand their rights and fight for the justice they deserve. Knowing where this chemical is used is the first step in protecting your family and recognizing if your illness could be connected to corporate negligence.

What Is Paraquat and Why Is It So Dangerous?

Paraquat is a non-selective herbicide, which means it kills nearly any plant tissue it comes into contact with. Its primary mechanism of action is creating oxidative stress, which causes cells to die. Unfortunately, this same process is believed to trigger severe damage in the human body, particularly in the brain.

Studies have shown that exposure to Paraquat can destroy dopamine-producing neurons, the very cells whose loss is the hallmark of Parkinson’s disease. This can lead to symptoms like tremors, muscle rigidity, loss of balance, and slowed movement. The risk is not just from long-term, low-dose exposure; acute poisoning from ingesting even a small amount of Paraquat is often fatal, and there is no known antidote.

The Top 3 Places for Paraquat Exposure in Los Angeles

While you might associate pesticide use with distant rural farms, Paraquat is used to manage vegetation in a variety of settings right here in Los Angeles County.

1. Agricultural Fields Bordering Los Angeles County

The vast agricultural lands in neighboring counties like Ventura, Kern, and Riverside are significant sources of Paraquat exposure for Los Angeles residents, especially those living near the county lines.

• What it’s used for: Paraquat is widely used to clear fields of weeds before planting crops like cotton, soy, and corn. It is also used to desiccate (dry out) crops to make harvesting easier.
• How exposure happens:
  • Spray Drift: This is the most common route of exposure for nearby residents. Wind can carry fine droplets of Paraquat for miles from the application site, blanketing adjacent homes, schools, and parks with the toxic chemical.
  • Direct Application: Farmworkers who mix, load, or spray Paraquat face the highest risk of direct exposure through inhalation or skin contact.
  • Contaminated Water: The chemical can seep into the ground and contaminate private wells, creating a source of long-term exposure for families.
• Who is most at risk: Farmworkers, their families (through “take-home” exposure on clothes), and anyone living or working in communities adjacent to these large agricultural operations.

2. Utility and Transportation Rights-of-Way

Crews responsible for maintaining critical infrastructure rely on powerful herbicides to keep vegetation from interfering with power lines, railroads, and freeways.

• What it’s used for: Clearing weeds and brush along freeway embankments, under high-voltage power lines, and along railroad tracks to prevent fire hazards and ensure access for maintenance crews.
• How exposure happens: Large-scale spraying operations along these corridors can produce significant spray drift. The chemicals can settle on nearby residential properties, playgrounds, and community spaces.
• Who is most at risk: Residents living in homes that back up to freeways or utility easements, children playing in nearby parks, and the grounds maintenance crews themselves.

3. Public Parks, Golf Courses, and Commercial Landscaping

While many municipalities are moving away from the most toxic chemicals, Paraquat and other potent herbicides have historically been used to maintain the pristine appearance of public green spaces.

• What it’s used for: Controlling weeds along pathways, in flower beds, and on the turf of parks and golf courses. Commercial landscapers may also use it to manage large properties.
• How exposure happens:
  • Direct Contact: People and pets can come into contact with the chemical by walking, playing, or sitting on grass that has been recently treated.
  • Inhalation: Breathing in the air during or shortly after a spray application can lead to exposure.
• Who is most at risk: Groundskeepers, landscapers, golfers, and families who frequent these public areas, including children and pets who are often closer to the ground.

Your Legal Rights as a Victim of Paraquat Exposure

If you or a loved one has been diagnosed with Parkinson’s disease and you believe you were exposed to Paraquat, you have the right to seek compensation. A successful lawsuit holds the manufacturers, like Syngenta and Chevron, accountable for allegedly hiding the dangers of their product.

To build a strong case, you will need to establish:

1. A history of exposure to Paraquat.
2. A medical diagnosis of Parkinson’s disease or evidence of acute poisoning.
3. A link between the exposure and your illness, which is typically established through expert testimony.

A successful claim can provide compensation for:

• All past and future medical bills
• Lost income and diminished earning capacity
• Pain and suffering
• The cost of lifelong care
• Punitive damages to punish the manufacturer
