WebJun 11, 2024 · Bioaccumulation is the sum of two processes: bioconcentration and biomagnification. Bioconcentration is the direct uptake of a substance by a living organism from the medium (e.g., water) via skin, gills, or lungs, whereas biomagnification results from dietary uptake. Many synthetic contaminants are more soluble in fat than in water.
