In Canada, more than half of all children ages 6 months to 5 years spend the largest part of their waking hours in early learning and child care facilities. During those hours, an important part of their time is spent on or near the ground, floor, and other areas where potentially harmful pests and pesticide residues may be present.
Because of their lower body weight, stage of development, and rapid metabolism, infants and toddlers are much more susceptible to pesticide poisoning than adults, according to The Canadian Partnership for Children’s Health and the Environment
They eat, drink, and breathe more than adults do, so they not only come into closer contact with more indoor pollutants, but are also more sensitive to them (since they will get a bigger dose per body size compared to adults). Young children also explore the world by touching objects and putting their hands in their mouths, which increases the risk of exposure to pesticides
and cleaning products.
