The hazards for humans and the environment are readily apparent in chemical emergencies. On the other hand, the risks from nongenotoxic effects of chronic exposures to low levels of chemicals are poorly understood. In particular, developmental toxicity studies should pay greater attention to the identification and biological evaluation of subtle effects as early indicators of damage and to the ...
