Biological and Economic Analysis Division (BEAD) Contacts

The Biological and Economic Analysis Division (BEAD) provides pesticide use-related information and economic analyses in support of pesticide regulatory activities.

Information about how much and the manner in which pesticides are actually used helps EPA evaluate potential exposures, the need for various pesticides and the potential economic impacts of regulatory options.

BEAD's laboratories validate analytical methods for pesticide residues, test public health antimicrobials to ensure that they work as intended and study genetic response to antimicrobial agents. These laboratories provide technical assistance to states and support state and federal compliance activities.
