Briefings

A new report reveals atrazine, a banned pesticide linked to cancer and birth defects, was detected in dangerous quantities in one-quarter of US rivers. The study, conducted by the Center for Biological Diversity, interviewed Aynsley O'Neill of Living on Earth and Nathan Donley, highlighting that the chemical is unnecessary for food production. Key findings include specific river locations and concentration levels, though the report notes data collection gaps and uncertainty regarding long-term ecological impacts.

Key points

• Atrazine was detected in one-quarter of US rivers at dangerous quantities, a finding supported by data from the Center for Biological Diversity.
• The chemical is banned in 63 countries and linked to multiple health issues, yet the report emphasizes it is not needed for food production.

Context

This article presents findings from a study by the Center for Biological Diversity, which interviewed Aynsley O'Neill of Living on Earth and Nathan Donley. The report highlights the paradox of a widely banned pesticide being found in significant amounts in US waterways, challenging the necessity of its continued use.

Limitations

The evidence is limited to a single study conducted in 2026, with data collection gaps noted in the report. Specific river locations and concentration levels are provided, but long-term ecological impacts and the full scope of atrazine's effects remain uncertain.
