An unprecedented study with major impacts

By understanding how prenatal exposure to environmental chemicals impacts the health of pregnant women and their infants, we can influence the policies and guidelines that help Canadians make decisions about their health. The MIREC Study is one of a few large-scale maternal-infant research cohorts in the world. We recruited 2000 pregnant women from 10 cities across Canada.
