A recent study by the McLaughlin Centre for Population Health Risk Assessment of the University of Ottawa finds that an increased risk of childhood leukemia is associated with the mother's exposure at work to pesticides.
"Childhood leukemia was associated with prenatal maternal occupational pesticide exposure in analyses of all studies combined and in several subgroups. Associations with paternal occupational pesticide exposure were weaker and less consistent. Research needs include improved pesticide exposure indices, continued follow-up of existing cohorts, genetic susceptibility assessment, and basic research on childhood leukemia initiation and progression."
