What are PFAS chemicals?

PFAS chemicals, or per- and polyfluoroalkyl substances, are a group of man-made chemicals that have been used in a wide range of products, including nonstick cookware, water-resistant clothing, and firefighting foam. PFAS chemicals are known as “forever chemicals” because they do not break down easily in the environment or the human body.

How are PFAS chemicals linked to delayed puberty in girls?

A new study has found that exposure to PFAS chemicals may delay puberty in girls. The study, which was published in the journal Environmental Health Perspectives, examined data from more than 800 girls. Researchers found that girls with higher levels of PFAS chemicals in their blood were more likely to experience delayed puberty.

The study’s authors believe that PFAS chemicals may delay puberty by interfering with hormone production. PFAS chemicals have been shown to mimic the effects of estrogen, a hormone that plays a key role in puberty.

What are the health risks of delayed puberty in girls?

Delayed puberty can have a number of negative health consequences for girls. Girls who experience delayed puberty are at an increased risk for developing breast cancer, kidney disease, and thyroid disease. They are also more likely to experience anxiety and depression.

What can you do to protect yourself and your family from PFAS chemicals?

There are a number of things you can do to protect yourself and your family from PFAS chemicals:

  • Avoid using nonstick cookware.
  • Wash new clothes before wearing them.
  • Use a water filter to remove PFAS chemicals from your drinking water.
  • Avoid eating fish that are known to be contaminated with PFAS chemicals.

If you are concerned about your exposure to PFAS chemicals, you can talk to your doctor about getting tested.


PFAS chemicals are a serious health hazard. Exposure to PFAS chemicals has been linked to a number of health problems, including delayed puberty in girls. It is important to be aware of the risks and to take steps to protect yourself and your family from exposure.
