Abstract
Purpose Sorption studies of organic micropollutants to sediments are useful for predicting their fate and transport. They allow for a better understanding of the migration of contaminants through environmental media, the exposure of aquatic organisms to such chemical and their affect on human health. Materials and methods This study examined the sorption of carbamazepine, ketoprofen, diclofenac, bisphenol A and triclosan onto sediments sampled along a dam reservoir. The sediments differed in structure, chemical composition and particle size distribution. The potential effect on the quality of drinking water through the removal of micropollutants by sorption was also estimated. Results and discussion Sorption isotherms of micropollutants were constructed at pH 7.6 on three natural sediments. The sorption points were determined by measuring the concentrations of analytes in both the solution and sediment samples. The results of partitioning coefficients suggest that triclosan (187.5–1248.5 μg1-1/n l1/n kg−1) and bisphenolA (11.4–51.0 μg1-1/n l1/n kg−1) exhibited relatively higher sorption, whereas ketoprofen (1.3–2.0 l kg−1), diclofenac (4.8–5.5 l kg−1) and carbamazepine (2.9–5.5 l kg−1) did not sorb to the studied sediments. The affinity of all micropollutants was higher for the finest sediment with the highest content of organic carbon and clay minerals, collected in the deepest part of the reservoir near the water intake. Conclusions The low values of partitioning coefficients suggest that all of the tested micropollutants, except triclosan, are predominantly freely dissolved, which can have an adverse effect on the quality of drinking water.
