Question DERBI section Responsive content
Note: Typical participant questions were first published in Brody et al. (2007).
What did you find?
How much?
Is that high?
Where did it come from?
Chemicals We Found Personalized headlines highlight key exposure results defined by the research team.
Strip plots show individual results for each chemical in relation to other study participants and a reference group.
Text for a chemical group gives a brief history of use and potential sources of current exposure.
Is it safe? Health Concerns Groups of chemicals are affiliated with potential health effects, such as promoting cancer or affecting fertility.
Language acknowledges uncertainty and warns against drawing a causal link between exposure results and illness.
How can I limit my exposure? What You Can Do Options for reducing exposure are organized by area, such as food or clothing, and address opportunities for (and limits on) individual and collective action.
What did you learn? Overall Study Results Text and graphs show what the research team has learned so far and provide broader public health context for individual results.
