About MIREC

Recent reports have raised concerns about the number of chemicals in our bodies and the potential health effects that may be associated with the levels measured. Canadian data on this issue are limited.

The MIREC Study had the following objectives:

  • to measure the extent to which pregnant women and their babies are exposed to common environmental chemicals;
  • to measure some of the beneficial elements in maternal milk;
  • to assess what health risks, if any, are associated with the chemical levels measured, with a focus on heavy metals such as lead and mercury;
  • to create a data and biological specimen bank for further research on fetal growth, pregnancy and health of mother and baby.

MIREC is the « mother branch » or foundation of what we hope to be a long list of follow-up studies that will look at various aspects of the MIREC children’s health as they grow up. We have already completed one follow-up study of the MIREC babies at birth and 6 months of age (called MIREC-ID), as well as two follow-ups called MIREC-CD3 and MIREC-CD Plus. You will find a summary of these studies in the MIREC & Follow-Up Studies section.

MIREC has created a large Biobank of specimens and data collected for future research on the health of mothers and their children. About 97% of the MIREC participants consented to be part of the Biobank. You will find a summary of the first five projects that were conducted, using the Biobank material, in the Researchers section.

Any researcher interested in accessing the MIREC Biobank to conduct research on the health of mothers and children can contact the Biobank Manager, for more information on the application procedure: (+1) 514-345-4931, ext. 4267.
