Program Description

People are exposed to a multitude of environmental toxicants through the air we breathe, the food and water we consume, and the products we use in our home or on our bodies. Scientists work to understand the implications of these complex chemical mixtures, which can sometimes produce health effects greater than each chemical would alone.

For example, exposure to ozone and aldehydes, which are components of smog, produces greater health effects than would be predicted based on each chemical alone. Similarly, smokers who are also exposed to radon or asbestos have a greater risk of developing lung cancer.

What NIEHS is doing

Historically, exposure research has studied the health effects of single chemicals at specific times, but there is a growing effort by NIEHS-funded scientists to develop methods to study environmental exposures in ways that more closely represent the mixture of exposures that we experience in modern life.

Researchers examine how these mixtures interact in cells, animals, and humans to determine health effects. They develop innovative statistical methods for assessing health effects of mixtures and characterizing real-life exposures.

The NIEHS Superfund Research Program also supports research of mixtures on human health and the environment.
