Environmental Data

What it Can Tell Us

Environmental data can tell us something about the sources of possible exposures, such as the levels of chemicals people may breathe or people's proximity to certain chemicals or facilities that use or release chemicals. The more actual data we have about the level of chemicals that people might breathe, drink, eat or touch, the more we know about exposure.

What it Cannot Tell Us

None of these data directly measure people's exposure (the levels of chemicals in people by breathing, ingestion or contact with skin). For exposure information, see Exposure Data.

We identify the type of data or information and suggest what it might tell you about chemicals in the environment or exposure.
