Research | Children’s Health Allergy and Sensitization during Childhood Associated with Prenatal and Lactational Exposure to Marine Pollutants
Ba c k g r o u n d: Breast-feeding may affect the risk of developing allergy during childhood and may also cause exposure to immunotoxicants, such as polychlorinated biphenyls (PCBs), which are of concern as marine pollutants in the Faroe Islands and the Arctic region. Objectives: The objective was...
