Sorption of emerging organic micropollutants onto fine sediments in a water supply dam reservoir, Poland

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 μg 1-1/n l 1/n kg −1 ) and bisphenolA (11.4-51.0 μg 1-1/n l 1/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. ConclusionsThe 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.

Supramolecular Solvent-Based Microextraction of Selected Anticonvulsant and Nonsteroidal Anti-Inflammatory Drugs from Sediment Samples

“…In studies of pharmaceuticals adsorption in river sediment samples, it was shown that the sorption of carbamazepine and diclofenac was higher than for ibuprofen, namely KD for CBZ was in the range of 5.57-24.55 L kg −1 and KD for DIC was 4.04-33.01 L kg −1 [55]. Similar results were also obtained for soil samples collected from dam reservoirs, where KD of CBZ was 2.9-5.5 L kg -1 , and 4.8-5.5 L kg −1 for DIC [20], and in tropical soil samples CBZ was 0.83-3.38 L kg −1 [56].…”

“…Procedures to produce SUPRAS solvents compatible with chromatographic and electrophoretic techniques are currently being developing [20]. Very often, supramolecular solvent-based microextraction (SUPRAS microextraction) uses decanoic acid (DeA) with tetrahydrofuran (THF) as the amphiphilic compound.…”

“…Very often, supramolecular solvent-based microextraction (SUPRAS microextraction) uses decanoic acid (DeA) with tetrahydrofuran (THF) as the amphiphilic compound. To obtain the best concentration factors, an appropriate volume of SUPRAS and amount of decanoic acid and THF should be selected [20]. It is also necessary to choose the appropriate extraction temperature, the addition of salts, bases, acids, alcohols, polymers, and other organic compounds [21,22].…”

Cellulose membrane modified with polypyrrole as an extraction device for the determination of emerging contaminants in river water with gas chromatography–mass spectrometry

“…In the last decade, new sorbents and approaches to SPE have been developed that improve the selectivity of existing commercial phases and lower the cost of analyte extraction. New sorbents for preconcentration of trace elements is a common subject, and some novel materials have been developed recently, such as molecularly imprinted polymers, carbon nanotubes, nanoparticles, biosorbents, and conducting polymers .…”
