Study of Exposure to Chemicals in Consumer Products
Background:
\- 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 them because the companies that sell the products don t have to tell the exact chemical ingredients. Researchers want to compare how existing methods (e.g., surveys and models) measure exposure to chemicals in personal care and household products.
Objective:
\- To test and improve the ways that studies gather data about contact with chemicals found in consumer products.
Eligibility:
\- Healthy women volunteers ages 35 74 who use at least 15 consumer products a day.
Design:
* Participants will be screened with medical history, pregnancy test, smoking test, and blood sample. They will answer questions about their homes and products they use.
* Participation will last about 30 hours over 12 days.
* Researchers will:
* Place air samplers inside and outside participants homes for 10 days. One sampler will need to be plugged into an electrical outlet. It will make a low, continuous sound while in operation.
* Collect house dust samples and record all consumer products in the house.
* Visit the house daily to collect samples.
* Participants will:
* Give a blood sample at a clinic twice.
* Collect all urine voids for 10 days. They will label it and put it in a special cooler.
* Wear 4 small devices that measure air pollution, chemicals, location, and activity.
* Record what they eat and what consumer products they use. They will write these in a diary and \<TAB\>photograph them on an iPhone provided to them.
* On day 2 of the study, they will collect a duplicate sample of what they eat.
* Take iPhone videos of their use of certain products.
* Answer questions about chemical ingredients in their personal care products.
Gender: FEMALE
Ages: 35 Years - 74 Years
