A precision environmental health approach to prevention of human disease

Human health is determined by the interaction of our environment with the genome, epigenome, and microbiome, which shape the transcriptomic, proteomic, and metabolomic landscape of cells and tissues. Precision environmental health is an emerging field leveraging environmental and system-level ('omic) data to understand underlying environmental causes of disease, identify biomarkers of exposure and response, and develop new prevention and intervention strategies. In this article we provide real-life illustrations of the utility of precision environmental health approaches, identify current challenges in the field, and outline new opportunities to promote health through a precision environmental health framework. Precision environmental health leverages environmental and system-level data to understand underlying environmental causes of disease, identify biomarkers of exposure, and develop new prevention and intervention strategies. In this Perspective, the authors provide real-life illustrations of the utility of precision environmental health approaches and identify current challenges in the field.
