The amount of substance found in the environment (such as water, soil, and air) relates to the concentration of pollutants. Pollutant concentration analysis is a helpful tool for evaluating how effectively procedures for waste treatment and regulatory constraints reduce contamination concentrations. Because of this, the Bodewadt flow of ternary hybrid nanofluid movement over a stretched disk in the existence of a porous medium and a concentration of pollutants is examined in the current investigation. The present analysis mainly focuses on the impact of external pollution sources on the concentration of pollutants. By applying the appropriate similarity variables, the governing equations for the flow and concentrations, which are in the form of partial differential equations (PDEs), are converted into a system of ordinary differential equations (ODEs). Utilizing graphs, various significant non-dimensional parameters and some engineering coefficient influences will be explained. local pollutant external source parameter and the Lewis number impact on the concentration profile is evaluated. The concentration of the fluid motion improves as the local pollutant external source parameter escalates while reduction of concentration is seen in the case of Lewis number. Enhancement in the volume fraction upsurges the concentration of the fluid motion and drops the velocity of the fluid motion. Raise in the stretching strength parameter, drop the Sherwood number and rises the skin friction coefficient.
