Toxic Exposure: Chemicals Are in Our Water, Food, Air and Furniture

When her kids were young, Tracey Woodruff, PhD, MPH, knew more than most people about environmental toxics. After all, she was a senior scientist at the Environmental Protection Agency (EPA). But even she never dreamed, as she rocked her children to sleep at night, that the plastic baby bottles she used to feed them contained toxic chemicals that could leach into the warm milk. 

Back then, in the late 1990s, it wasn’t widely known that the chemicals used in plastic sippy cups and baby bottles can potentially disrupt child development by interfering with the hormone system. That, in turn, could alter the functionality of their reproductive systems or increase their risk of disease later in their lives.

“When I had babies, I did many of the things we now tell people not to do,” says Woodruff, who for the past decade has been the director of UC San Francisco’s Program on Reproductive Health and the Environment (PRHE). Also a professor in the University’s Philip R. Lee Institute for Health Policy Studies, she earned her doctorate in 1991 from a joint UCSF-Berkeley program in bioengineering and then completed a postgraduate fellowship at UCSF. 

Woodruff’s children have since grown into physically healthy teenagers, but many children are not as lucky. Unregulated chemicals are increasing in use and are prevalent in products Americans use every day. Woodruff is concerned by the concurrent rise in many health conditions, like certain cancers or childhood diseases, and the fact that the environment is likely to play a role in those conditions. What motivates her is the belief that we need to know more about these toxics so we can reduce our exposure to the worst of them and protect ourselves and our children from their harmful effects. (Woodruff points out that the word “toxics” as a noun means any poisonous substances, from either chemical or biological sources, whereas “toxins” are poisons only from biological sources, either plant or animal.)
