In a lifetime, a person may encounter tens of thousands of chemicals used as ingredients in the products they buy. It’s not easy to measure these chemicals because the companies that sell the products aren’t required to divulge the exact chemical ingredients.
Researchers want to compare how existing methods, such as surveys and models, measure exposure to chemicals in personal care and household products. This study intends to test and improve the ways that studies gather data about how chemicals in products come in contact with consumers.
- Ages Eligible for Study: 35–74 years
- Genders Eligible for Study: Female
- Accepts Healthy Volunteers: Yes
- Individuals must be a non-smoker living in a non-smoking home. Individuals who are former smokers or live with a former smoker must be at least one year smoke free at the time of enrollment.
- Individuals must be non-pregnant and non-nursing at the time of enrollment.
- Individuals will not be selected for specific preexisting health conditions but will be excluded if any of the conditions described in Section 5.2 (EXCL 5) are present at the time of enrollment.
- Individuals who spend a majority of their time in the home each day will be recruited for this study. This includes individuals who work from home, are stay-at-home caretakers, retired, unemployed, etc.
- Individuals must use a high number of consumer products. A high consumer product user is someone who uses more than a certain number of products (e.g., 15 or more products a day). This number will be finalized following the completion of a separating screening activity by NIEHS under a separate IRB protocol, and will be defined prior to enrollment of participants in the study.
