The CHORDS project strengthens data infrastructure to facilitate research connections between environmental exposures and health outcomes. Exposures such as poor air and water quality, extreme temperatures, and natural disasters can cause both short-term health effects, like asthma attacks and heat stroke, and long-term conditions such as heart disease and cancer. By providing accessible, interoperable data and analytical resources, CHORDS supports researchers, health practitioners, and public officials in assessing environmental health risks, developing evidence-based interventions, and anticipating future health challenges to better protect communities.
