These values are determined … Four potential processes exist for a chemical interacting with an animal: absorption, distribution, metabolism and excretion (ADME). Absorption describes the entrance of the chemical into the body, and can occur through the air, water, food, or soil. Once a chemical is inside a body, it can be distributed to other areas of the body through diffusion or other biological processes. At this point, the chemical may undergo metabolism and be biotransformed into other chemicals (meta… WebToxicokinetics is the mathematical description of the uptake and disposition of a chemical in the body. Toxicokinetic modeling is usually implemented by describing the time course of the amount or concentration of the parent substance and its metabolites in one or several body compartments. georgia down payment programs
