Study: Pregnant women increasingly exposed to chemicals

A new study finds the amount of pregnant women becoming exposed to chemicals from plastics and pesticides is increasing.

The National Institutes of Health study included more than 170,000 women.

Researchers measured 103 chemicals. These chemicals can be harmful to pregnancy and child development.

The study found more than 80% of the chemicals were found in at least one of the women, and more than a third of the chemicals were found in a majority of the participants.

The study also found some of these chemicals were present in higher amounts than in previous studies.
