Table 1.
Quality of the eggs (egg, yolk, and shell mass; thyroid hormone concentrations: T3 = triiodothyronine, T4 = thyroxine, average ± SD) from GBH (glyphosate based herbicide)-exposed and control females. The egg mass was averaged over all eggs (4 and 12 months of exposure). The other parameters were measured after 4 months of exposure. See text for power analysis.
