Focusing on Children's Inhalation Dosimetry and Health Effects for Risk Assessment: An Introduction (Journal Article)
Substantial effort has been invested in improving children’s health risk assessment in recent years. However, the body of scientific evidence in support of children’s health assessment is constantly advancing requiring continual updating of risk assessment methods. Children’s inhalation dosimetry and child-specific health effects are of particular concern for risk assessment. When focusing on this topic within children’s health, key issues for consideration include: the epidemiological evidence of adverse effects following children’s exposure to air pollution, ontogeny of the lungs and effects on dosimetry, estimation and variability of children’s inhalation rates, and current risk assessment methodologies for addressing children. In this article, existing and emerging information relating to these key issues are introduced and discussed in an effort to better understand children’s inhalation dosimetry and health effects for risk assessment. While much useful evidence is currently available, additional research and methods are warranted for improved children’s health risk assessment.
