Research Interests

The effects of exposure to environmental contaminants on child development are of significant concern in view of the growing number of these contaminants. The issue is of great interest to the public, especially as this determinant of child development can be modified through interventions aimed at reducing exposure.

Dr. Maryse Bouchard specializes in studying the effects of environmental contaminants, such as metals (manganese, lead, mercury) and pesticides, on a child’s nervous system. Children are more vulnerable to exposure to neurotoxic substances, given that their nervous system is still developing and they receive a higher dose of exposure, given that they consume more food and water per body weight than do adults.

During her postdoctoral training at the Harvard School of Public Health in Environmental Neuroepidemiology, she identified links between exposure to various environmental contaminants and the prevalence of central nervous system disorders in the population using data from large-scale CDC studies. For example, she demonstrated that in the general population living in the USA:

• The prevalence of depression and panic disorder increases significantly with lead blood concentrations in young adults (20-39 years old);

• The prevalence of attention deficit/hyperactivity disorder increases significantly with urinary metabolite levels that indicate exposure to organophosphate pesticides.

In addition, she is now conducting an epidemiological study of 362 Quebec school-age children exposed to manganese present in underground drinking water. She recently reported that the concentration of manganese in drinking water was negatively associated with the children’s IQ scores. These findings support the hypothesis that exposure to manganese in drinking water induces neurotoxic effects that are associated with cognitive deficits in children.
