Children's susceptibility to environmental contaminants can vary significantly by life stage. The recent adoption by the US Environmental Protection Agency of a standard set of childhood age groups is proving instrumental in improving our ability to protect children by more consistently considering life-stage changes when assessing exposure, dose, and risk.
儿童对环境污染物的易感性会因生命阶段的不同而有显著差异。美国环境保护署最近采用了一套标准的儿童年龄组,这证明有助于提高我们的能力,通过在评估暴露、剂量和风险时更一致地考虑生命阶段的变化,来更好地保护儿童。
