Uncertainties in Estimates of Exposure via Dust Ingestion and Indoor Air Inhalation

5 Uncertainties in Estimates of Exposure via Dust Ingestion and Indoor Air Inhalation 

While there is a substantial body of evidence that suggests dust ingestion and indoor air inhalation are significant pathways of exposure, it is important to note that there remains a degree of uncertainty regarding the absolute magnitude of the exposure estimates upon which such evidence is based. We discuss here the principal causes of such uncertainty.
