Dartmouth Superfund Program (SRP) researchers Brian Jackson and Margaret Karagas and Trainee Hannah Laue (lead author) are co-authors of the paper Nutrient-Toxic Element Mixtures and the Early Postnatal Gut Microbiome and in a United States Longitudinal Birth Cohort. The study concluded that “Early postnatal toxic and nutrient elemental exposures are associated with differences in the infant microbiome. Further research is needed to clarify the whether these alterations are a biomarker of exposure or if they have implications for child and lifelong health.” The paper was  published in the journal Environment International.
