Even more surprising, the Wall Street Journal’s lead article that same day (7/25/05) focused on the challenge and puzzle of endocrine disruptors:

An especially striking finding: It appears that some substances may have effects at very low exposures that are absent at higer levels…. the new science of low-dose exposure is challenging centuries of accepted wisdom about toxic substances and rattling the foundation of environmental law.

Environmental law is founded of course, on the traditional dose-response curve: more stuff has more impact, less stuff has less impact. If that’s does longer correct, it tosses the notion of safe thresholds and acceptable tolerance into a cocked hat. And elevates the strategic attractiveness of ‘zero waste‘ and ‘cradle to cradle‘ approaches to both business strategy and product design.
