Exposure to a mix of pesticides raises risk of pregnancy complications, study suggests

Research looks at health impacts of being exposed to multiple pesticides versus just one substance

Exposure to multiple pesticides increases the chances of pregnancy complications compared to exposure to just one pesticide, new peer-reviewed research suggests. The findings raise new questions about the safety of exposure to widely used pesticides and herbicides in food and agricultural communities.

The study, which bio-monitored pregnant women in a heavily agricultural state in Argentina, adds to recent-but-limited evidence pointing to heightened dangers in mixtures of pesticides.
