Bioaccumulation is the process by which the chemical concentration in an aquatic organism achieves a level that exceeds that in the water, as a result of chemical uptake through all possible routes of exposure.The relationship between bioaccumulation and bio-concentration is that, chemicals that have the potential to bioconcentrate also have the potential to bioaccumulate. Bioaccumulation is closely related to the Bioconcentration factor (BCF).

The estimated BCF of the key study was obtained to be 3.2.Supporting studies indicate the BCF to be between 1 to 3. This low value of BCF of 2-aminobenzenesulphonic acidindicates its non bioaccumulative nature as the BCF factor is less than the bio-concentration threshold of 2000.
