Quantifying soil contamination and identifying interventions to limit health risks

Numerous toxicants contaminate soil and negatively affect the environments that children explore. Accurately measuring these toxicants and characterizing the level of soil contamination may be difficult and must include measurements of both the environmental concentrations and the exposure responses of human populations. This article reviews the current methods and technologies available for quantifying soil contamination. Several intervention strategies exist for limiting human exposure to contaminated soils and the strengths and weaknesses of these methods are discussed. Lastly, current policies on soil contamination and the importance of protecting vulnerable populations by developing means to improve health conditions for children are reviewed.
