About the Exposure Factors Handbook

EPA's Exposure Factors Handbook (EFH)

The latest edition of the Exposure Factors Handbook was released in 2011, but since October 2017, EPA has begun to release chapter updates individually. This new process allows risk assessors to get the latest information as new data becomes available.

To make it easier to find these chapter updates, the chapter date column has been added to Table 1.
