Farm Family Exposure Study on Glyphosate
Author Information
Author(s): Acquavella John, Alexander Bruce, Mandel Jack, Gustin Christophe
Primary Institution: University of Minnesota
Conclusion
The study found that urine collection completeness among farmers was exceptional, with only four samples below the expected daily excretion limit.
Supporting Evidence
- Only four 24-hr urine samples over 5 days were below the expected daily excretion limit.
- The highest systemic dose estimated in the study was 0.004 mg/kg/day, much lower than the EPA reference dose.
- Absorbed dose was related to specific practices, such as not wearing gloves.
Takeaway
Farmers in the study had very good urine sample collection, showing they were exposed to glyphosate during pesticide application.
Methodology
The study assessed urinary glyphosate levels in farmers over a 5-day period.
Potential Biases
Potential bias due to not correcting for pre-application urine values.
Limitations
The study only evaluated one application per farm family, which may limit the understanding of exposure variation.
Participant Demographics
Farmers and their families involved in pesticide application.
