> The approximate dose where this effect likely just begins to occur
Don't effects like this usually "begin" at a dosage of zero? If the effect size ends up being 0.001 points of IQ lost at a reasonable dosage, I don't particularly care whether scientists prove that there's a casual and statistically significant effect. Doesn't matter either way
not necessarily; consider hormesis, a two-phased dose response -- something can be highly beneficial at a low dose, then ineffective or simply toxic at higher doses
No, toxins usually have no effect, or a totally different effect until some the threshold dose.
