How Does a Concentration Gradient Affect Toxicant Absorption?
The concentration gradient significantly influences the absorption of toxicants. When a toxicant is introduced into the body, it often moves from the site of exposure (where its concentration is high) to other areas (where its concentration is lower). This movement is primarily driven by passive diffusion, where substances move along the concentration gradient without the need for energy. The steeper the gradient, the faster the rate of diffusion, affecting how quickly a toxicant can exert its effects.
