Level 3 - non-randomized controlled study
Longitudinal observational cohort study tracking biomonitoring levels over time
PubMed 29067413 · doi:10.1001/jama.2017.11726
What was done
Urinary levels of the herbicide glyphosate were measured among older adult participants in the Rancho Bernardo Study of Healthy Aging between 1993 and 2016.
What was found
The abstract reports no numerical findings, exposure concentrations, detection frequencies, or directional trends.
Why it matters
Biomonitoring across a 23-year period can document long-term population exposure trends following the adoption of genetically modified crops.
Limits
The abstract reports no sample size, participant demographics, analytical assays, detection limits, dietary exposure sources, or health outcomes.
