Growing children absorb more of what they ingest than the average adult. When we think of growing children, we often think of that absorption in terms of nutrients, but studies have shown that children also absorb more contaminants than the average adult. With a lower body weight and increased contaminant absorption, children are at a higher risk of negative effects from pollution and contamination. Because of this, it is vital to ensure schools and childcare facilities aren’t a source of toxic exposure for growing children. Known risks include lead and copper contamination from old plumbing, lead from old lead-based paint, and pesticides sprayed around structures. To address exposure concerns, testing for schools and childcare centers can include pesticides, dioxins, and heavy metals.
