MIREC is a national five-year research study that is recruiting about 2,000 women from the following cities: Vancouver, Calgary, Winnipeg, Sudbury, Ottawa, Kingston, Hamilton, Toronto, Montreal and Halifax. Women will be recruited during the first trimester of pregnancy and followed through pregnancy and up to eight weeks after birth. Participants must be 18 years of age or older and six to 12 weeks pregnant to be eligible for the study.
The main goals of this study are: to measure the extent to which pregnant women and their babies are exposed to environmental chemicals, as well as tobacco smoke; to assess what pregnancy health risks, if any, are associated with exposure to heavy metals (lead, mercury, cadmium, arsenic and manganese); to measure the levels of environmental chemicals and some of the beneficial components (nutritional and immune constituents) of breast milk.
The MIREC study will generate new knowledge on Canadians' exposure to environmental chemicals. This information will help to strengthen health risk assessments and support measures to reduce the release of contaminants into the environment and to limit Canadians' exposure.
