Models

When EPA assesses the risk of a pesticide to human health or the environment, it considers the toxicity of the pesticide as well as the amount of pesticide to which a person or the environments may be exposed. In assessing exposure, scientists frequently use mathematical models to predict pesticide concentrations in food, water, residential, and occupational environments.

• Aquatic Models

  OPP uses aquatic models to estimate pesticide concentrations in food, water, non-target organisms, residential and occupational environments. These estimated concentrations are used to assess exposure to aquatic organisms, humans, and the environment.

  EXPRESS, FIRST, KABAM, PFAM, PRZM-GW, SCIGROW, SWAMP, SWIMODEL, SWCC, Tier I Rice Model

• Terrestrial Models

  OPP uses terrestrial models to estimate pesticide concentrations on avian and mammalian food items and exposure and risk to terrestrial organisms from pesticide use.

  BeeREX, MCnest, SIP, STIR, T-HERPS, T-REX, TerrPlant, TIM

• Atmospheric Models

  OPP uses atmospheric models to predict the deposition patterns of pesticides released into the atmosphere.

  AGDISP^TM, AgDRIFT^®, FEMS, PERFUM, SOFEA

• Health Effects Models

  OPP uses health effects models to predict effects to humans from exposure to pesticides.
