Reproductive disorders, chemical industry

First, although there is substantial evidence that many cancers are primarily associated with so-called lifestyle factors , the natural environment including viruses, and even genetics, we certainly cannot rule out some role for industrial chemicals. Moreover, chemicals can cause many other types of adverse health effects about which we do not have significant explanations of any type. Until we have evidence to rule out a significant role for industrial pollutants in human reproductive disorders, diseases of the nervous system, and so on, it would seem imprudent to cease or reduce gathering toxicity data on them and establishing limits on human exposures.
