What Role Does Molecular Diffusion Play in Toxicant Distribution?
After absorption, toxicants are distributed throughout the body, largely through the bloodstream. Molecular diffusion plays a crucial role in this process, as it facilitates the movement of toxicants from the blood into tissues and organs. Factors such as blood flow, tissue permeability, and the chemical properties of the toxicant determine the rate and extent of distribution. Compounds with high lipid solubility or affinity for tissue proteins may accumulate in specific organs, leading to potential bioaccumulation and toxicity.
