Biomagnification Biomagnification is the process where chemicals accumulate AND become more concentrated at each trophic level of the food chain. BIOACCUMULATION Bioaccumulation refers to the accumulation of substances.
• Accumulation is measured in parts per million (ppm). • This refers to one particle of the chemical out of 1 million particles. ... Consider the food chain: ...
Thus, bioconcentration and bioaccumulation occur within an organism, and biomagnification occurs across trophic (food chain) levels. Biodilution is also a process that occurs to all trophic levels in an aquatic environment; it is the opposite of biomagnification, thus a pollutant gets smaller in concentration as it progresses up a food web.
