Why industry needs to adopt the precautionary principle:
Article says:
For centuries, the basic rule of toxicology has been "the dose makes the
poison." Now, the scientists say "the timing makes the poison" - in other
words, when a toxic exposure occurs is as important as the amount people are
exposed to.

Among the risky chemicals they named are bisphenol A, found in polycarbonate
plastic food and water containers; the pesticides atrazine, vinclozolin and
DDT; lead; mercury; phthalates used in some cosmetics and soft plastics;
brominated flame retardants; arsenic, which contaminates some water
supplies; and PCBs, banned but ubiquitous, particularly in fish.

Some of the chemicals have been regulated in the United States, but many
have not. Moreover, the scientists said, tests for developmental effects are
not routinely required, so "the potential for such effects is therefore not
necessarily considered in decisions on safety levels of environmental
exposures."

There is "an incredible gap," Landrigan said, because 80% of major chemicals
in commerce have never been tested to see if they damage early development.
