Paraquat and Parkinson’s Disease















What is Paraquat? Paraquat, also known as Gramoxone, is an herbicide primarily used for weed and grass management. However, According to the CDC (Centers for Disease Control and Prevention), It is a toxic chemical. The CDC also states that the highly poisonous herbicide marketed to the United States has safeguards such as a blue dye, a sharp odor, and an added agent that induces vomiting if ingested. These safeguards are in place to warn potential users of its toxicity. Because this herbicide is so toxic and can lead to fatal poisoning, only licensed professionals can use it.

Why is Paraquat Used? The herbicide kills weeds and unwanted grasses because of its incredible effectiveness, which is why, in the United States, commercial farmers and agricultural workers have used this product to control their land’s unruly weeds and grass since 1964. Before harvest, it also is used as a defoliant on crops, such as cotton. There are many uses for this herbicide, but unfortunately, the consequences can be fatal. 

How can you get poisoned by Paraquat? Acute poisoning can occur because of accidental ingestion, inhalation, or skin exposure by an individual. It can cause damage to the lungs, intestines, stomach, and mouth when ingested in small amounts, while in large quantities, it can damage multiple organs and lead to death within hours. The most common way of getting poisoning from this herbicide is by accidentally ingesting it. Unfortunately, there is no antidote after getting poisoned by this toxic chemical.

What is Parkinson’s disease? Parkinson’s disease is a neurodegenerative disease that affects mobility. Symptoms may begin to show themselves slowly, like a slight tremor in one hand. In fact, with this disease, tremors are very common. In addition, slowed or slurred speech and your face showing little or no expressions are symptoms. This disease, unfortunately, cannot be cured. However, some medications can improve symptoms significantly. 

What does Paraquat have to do with Parkinson’s disease? Numerous studies report a link between long-term Paraquat exposure and Parkinson’s disease. According to these studies, Paraquat increases the risk of getting Parkinson’s disease due to its ability to create oxidative stress that damage and kill dopamine neurons. A quote from Unified Parkinson’s Advocacy Council states, “On behalf of the Unified Parkinson’s Advocacy Council, we write to express our concern with paraquat dichloride (“paraquat”), which is shown to increase risk of Parkinson’s disease (PD). We ask the Environmental Protection Agency (EPA) to deny the reregistration of this herbicide based on strong evidence of paraquat’s harm to human health.”
