EPA has released its 2011 Exposure Factors Handbook. The 1,400 plus-page handbook provides a summary of available statistical data on various factors risk assessors use when calculating human exposure to environmental agents. The factors addressed include (i) drinking water consumption; (ii) soil ingestion; (iii) inhalation rates; (iv) dermal exposure; (v) consumption of fruits and vegetables, fish, meat, and dairy products; (vi) human activity factors; (vii) consumer product use; and (viii) building characteristics. The handbook, last produced in 1997, provides recommended exposure values for the general population and for special populations.
