The binding of hydrophobic organic micropollutants to humic substances in humic water can prevent the pollutant's bioavailability. On the other hand, leads the conglomerate formation between toxic pollutants and humic matter in the aquatic environment to increased mobility of the toxic units. It is evident from the reviewed literature that the changes in pH of the aqueous phase can alter the sorption capacity of humic matter for organic micropollutants. The mechanisms for these changes should be sought in the specific surfaces of the humic substances. The lowering of the pH in the water may cause a decrease in sorption capacity on the humic compounds, thus directing the main flux of the pollutants toward the sediment. A raise in pH may cause a significant release of micropollutants from the sediment toward the humic substances in the water phase. It is desirable to incorporate the binding phenomena between organic micropollutants and dissolved humic matter in pollutant fate models
