Health-Based Rules and Guidance for Air

Air Values Table

The Minnesota Department of Health (MDH) develops health-based rules and guidance to evaluate potential human health risks from exposures to chemicals in ambient air. This guidance is developed at the request of MDH programs and other state agencies, such as the Minnesota Pollution Control Agency (MPCA).

A Health Risk Value (or guidance value for air) is defined as the concentration of a chemical (or a defined mixture of chemicals) that is likely to pose little or no risk to human health. These values are expressed in micrograms per cubic meter of air (µg/m3). HRVs are developed to protect human health for a specified length of exposure (e.g., one hour, 13 weeks, a lifetime).
