Document Summary
1. children"s environmental health: different exposure patterns between children and adults. Babies that drink breast milk (can be infected with dioxins, ddt) vs formula (need good quality water) 3-4 times more food in proportion to their body size than adults. Drink more water relative to their body weight. Mouthing behaviour (2-6 year-olds touch their mouths about 9 times every hour) Participation in certain athletics and/or risky activities. How and where children spend their time. Crawling and playing on the floor (dust, pollutants, infectious agents, radon) Playing on the grass (pesticides, skin infections) The breathing zone of the adults is 4-6 feet above the floor or ground. For children it is much lower: physiological differences between children and adults. More active than adults (eat more, drink more, breath more air relative to body weight) Higher ratio of skin surface area to body. Large surface area of intestines; more chemicals can go through.
