Developing an Exposure Burden Score for Chemical Mixtures Using Item Response Theory, with Applications to PFAS Mixtures
Science
2 Nov 2022 | Environ Health Perspect
A novel exposure burden score method for chemical mixtures was developed and applied to estimate the exposure burden of PFAS mixtures and resulted in stronger estimated associations with cardio-metabolic outcomes in the general U.S. population compared to summed PFAS concentrations.
