The I4C includes mother-infant cohorts in Europe, Israel, and Australia and over 300 cases of childhood cancer. We are leading analyses of occupational and residential exposure to agricultural pesticides in the Danish National Birth Cohort (DNBC), the Norwegian Mother and Child Cohort (MoBa), the Avon Longitudinal Study of Parents and Children, the Tasmanian Infant Health Survey, and the Jerusalem Perinatal Study and residential exposure (based on geocoded birth residence and questionnaire) in DNBC and MoBa. Analyses are being led by Ben Booth, a pre-doctoral fellow in OEEB as part of his dissertation research
