Glyphosate exposure and GM seed rollout unequally reduced average birthweight and gestational length
Proceedings of the National Academy of Sciences, FREE PDF is online
Main Finding: Average birth weights declined with increased maternal exposure to glyphosate, with the most vulnerable (lowest expected birthweight) infants experiencing losses up to 4% of their expected weight.
Other Findings:
On average, birth weight was reduced by roughly 29.8 grams (about 1%) at standard exposure, but the impact rose for subgroups—up to 4% for infants in the lowest birth weight decile, or higher for those with very high exposures.
Pregnancy duration was also shortened by an average of 1.49 days.
The highest-exposed group (1% of rural births) saw birthweight reductions as high as 5–9%.
