Many endocrine disruptors have U shaped 'potency' curves. In practice this means that in very small amounts the body treats it as a hormone signal, in medium amounts there is almost no response, and in high amounts it will be toxic. This U shaped curve is what makes the small amounts that leech from everywhere very serious. The bodily response is much more complex than "more is worse"
