bioaccumulation factor

initialisms: BAF, BF
synonym: accumulation factor

Ratio of tissue chemical residue to chemical concentration in an external environmental phase (e.g., sediment, water, soil, air, or food). BAF is measured at a steady state in situations where organisms are exposed to multiple sources (e.g., water, sediment, food), unless noted otherwise.
Notes:
  1. The concentration in the organism is typically expressed per unit body mass or per gram of lipid (bioaccumulation factor, lipid-based).
  2. The concentration in sediment may be expressed per gram dry weight of sediment or per gram of organic carbon and may be referred to as the biota-sediment accumulation factor (BSAF).
  3. The compound may have entered the organism by any available route and from any component of the water or sediment.
  4. In relation to uptake from food, the concentration in the organism is typically expressed per unit body mass or per gram of lipid and the concentration in food is expressed per gram dry weight of food.
