Pesticide exposure in rural areas linked to Parkinson’s

Inhaling environmental pollutants such as weed and insect sprays can increase the risk of Parkinson’s Disease.

People living in rural areas have a higher risk of developing Parkinson’s Disease due to exposure to chemicals used in agricultural and horticultural sprays, according to research charity Cure Parkinson’s.

They say it’s not just farmers, orchardists, vineyard workers and gardeners actually using the chemicals who are vulnerable, but anyone living near where weedkillers and insecticides are sprayed.

Products containing paraquat, heptachlor and rotenone are among the worst offenders, with studies showing they can increase the risk of Parkinson’s by 200 to 600 per cent, depending on exposure levels. Now banned in many countries, products containing paraquat are still available in NZ, although they are restricted, while rotenone remains a common garden pesticide – better known as Derris dust or spray.

Cure Parkinson’s community engagement lead Lizzie Drum says people should be wary around any industrial chemicals, as inhaled pollutants may cause inflammation, cognitive issues and neurodegenerative diseases such as Parkinson’s.

“It’s very much a disease of our industrial era. There is little doubt that Parkinson’s is caused, at least in part, if not to a large extent, by exposure to environmental pollutants,” she says.

“People should follow precautions when using any industrial chemicals, as many associations are proposed but remain unproven.

“Protecting your nose is crucial for brain health, because it serves as the main entry point for air and inhaled substances, including pollutants and pathogens, which can directly reach the brain.”

Parkinson’s Disease is the fastest-growing neurological condition globally and is now the second most common progressive neurological disorder after Alzheimer’s. It affects more than 13,000 New Zealanders and costs the country $600 million annually.

“Pesticides can have neurotoxic effects that may contribute to the development of disease by damaging neurons that produce dopamine, a neurotransmitter crucial for motor control – a common symptom of Parkinson’s that includes tremors, stiffness and slowed movements.”

She says anyone using chemical sprays should wear protective gear, especially a mask to protect their nose – and brain.

Cure Parkinson’s, together with the Dairy Women’s Network, will host a live webinar to discuss the issue on Wednesday, September 24, between noon and 1pm. The charity’s chief executive Dr Daniel McGowan will look at the connection between long-term exposure to agricultural and horticultural chemicals, and the increased risk of developing Parkinson’s. He will also outline early warning signs of the disease, such as tremors, loss of smell or changes in coordination, and look at practical steps anyone who uses herbicides and pesticides can take, such as wearing protective clothing or sourcing alternative products.
