Are you breastfeeding or pregnant with your first child? You may be eligible to take part in the Healthy Moms, Healthy Kids study.

This study will test breastmilk to look for toxic chemicals such as flame retardants and nonstick PFAS chemicals. Adults and children can be exposed to many toxic chemicals from consumer products like electronics, building materials, and furniture. For many chemicals found in our homes, we don’t know enough about how much they are building up in our bodies and being passed on during breastfeeding.

Our findings will help us understand how babies are exposed to chemicals linked to health problems such as learning disabilities and immune problems. We will use the results to inform doctors, scientists, policymakers, and companies to promote the use of safer materials in consumer products.

Chemicals end up in our bodies when we inhale them, ingest them through food, dust, or water, or absorb them through our skin. Some of these chemicals can build up, and a woman who is pregnant may pass them to her developing fetus. Chemicals can also be passed to the child during breastfeeding. Even though breastmilk may contain harmful chemicals, breastfeeding is still healthier than formula bottle-feeding for both babies and mothers and is the best way a mother can feed her baby.

Participants of the study must meet the following criteria:

  • 18 years of age or older
  • Pregnant in the third trimester or breastfeeding first child
  • Live in Washington State

If you join our study, your participation will include:

  • Providing a breast milk sample
  • Completing a questionnaire

If you meet the study criteria and are interested in participating in this study, please fill out the form and we will be in touch with further information.

This study builds on Toxic-Free Future’s history of advocating for and winning strong protections against toxic chemicals. Backed by science, including our own scientific research, we work to create a healthier world for you, your patients, family, and community. Recently, our work to identify and restrict toxic chemicals led to new Washington State laws protecting drinking water and food from harmful nonstick chemicals known as PFAS.
