Scientific research is renewing questions about the safety of atrazine, a widely used herbicide in U.S. agriculture. Experts are examining whether long term exposure may be linked to serious health conditions, including non-Hodgkin lymphoma.
Atrazine has been used for decades on major crops such as corn and soybeans. Over time, it has been found in groundwater, rivers, and private wells near farming areas. This widespread presence has raised concerns for people who live or work close to treated fields.
In 2025, the International Agency for Research on Cancer reviewed existing data and classified atrazine as probably carcinogenic to humans. The agency reported that the chemical can cause oxidative stress, inflammation, and immune system disruption, which are known pathways linked to cancer development.
"Atrazine is much more strictly regulated in the European Union. It was banned in 2004 when regulators determined that the chemical's groundwater contamination was ubiquitous and unpreventable. Despite international restrictions, atrazine remains readily available in the U.S," said Health Policy Watch. Timothy A. Loranger, attorney and senior partner at Wisner Baum.
Further evidence was provided by a University of Nebraska Medical Center study in 2025. Researchers examined long-term environmental monitoring records, including tens of thousands of groundwater and surface water samples. The study found atrazine contamination in a large percentage of private wells across rural farming counties.
While many countries have restricted or banned atrazine, it remains legal in the United States. Health Policy Watch reports that at least 60 countries no longer allow atrazine due to environmental and health concerns.
According to the U.S. Environmental Protection Agency, roughly 72 million pounds of atrazine are used each year. Scientists warn that the chemical can remain in water for extended periods, increasing exposure risks for rural communities.
Wisner Baum is reviewing cases involving people diagnosed with non-Hodgkin lymphoma after long term atrazine exposure. The investigation focuses on occupational and environmental exposure and examines whether warnings were sufficient.
