Kabam Overview



KABAM links hydrophobic organic pesticide bioaccumulation in aquatic components of a food web to terrestrial exposure in birds and mammals. Given the dual ecosystem emphasis, KABAM is divided into two portions: 1) an aquatic bioaccumulation model and 2) a terrestrial risk component. The bioaccumulation model is based off of a widely accepted model by Arnot and Gobas (2004) developed to evaluate PCB and select pesticide transfer through Great Lakes ecosystems. Dietary and respiratory exposures are estimated using a pesticide’s octanol-water partition coefficient (KOW). The terrestrial risk component follows EPA’s TREX model. KABAM spans all trophic levels from aquatic primary producers and consumers to aquatic and terrestrial predators (Figure 1).

To use KABAM effectively, a pesticide must adhere to all 3 of the following characteristics:

  • Be chemically non-ionic and organic
  • Log KOW; range = 4 – 8
  • Can reach aquatic habitats
