Sorption of hydrophobic contaminant

For example, if the reaction controlling the sorption of each molecule of a contaminant is identical and the capacity of a sorbent for these molecules is operationally limitless, a linear isotherm relationship is prescribed in which the sorbed-phase concentration is a constant proportion of the solution-phase concentration. When the sorption reactions are identical but sorption capacity is limited, an asymptotic approach to a maximum sorbed-phase concentration might be expected. These two limiting-condition models have been described and compared with others for description of the sorption of hydrophobic contaminants on a variety of natural soils, sediments, and suspended solids...

A team of scientists adapted the fugacity model CEMC SFU Agro to assess the fate of chemicals within pisdveorous fish whose diet included a 10% microplastic component. The model indicated that bioaccumulation of chemicals would actually decline as a result of the sorption of hydrophobic contaminants into the plastic within the organism. In other words, the plastic particles would serve as a sink rather than a source of anthropogenic chemicals. For chemicals with a log between 6.5 and 7.5, the model predicted that the body burden concentration would decrease by more than 20% if the diet contained 10% microplastics [148].
