Exposure Biology


The field of exposure biology focuses on unraveling how the toxicants a person is exposed to during life can interact with each other, with lifestyle factors, and with a person's genes to cause disease.

NIEHS currently supports the development of innovative technologies to measure environmental exposures such as toxicants, diet, physical activity, psychosocial stress, and addictive substances.

The goal is to advance environmental health by looking at collections of environmental exposures rather than single events and by measuring exposures more precisely than has previously been possible.
