“…Co-introduction of PCs and their metabolites to soils via application with reclaimed wastewater irrigation may lead to possible competition for sorption sites on soil particles (Pan et al, 2009). Competitive effects of lamotrigine and carbamazepine and vice versa were not observed neither at 10 nor at 100 mg L À1 of the respective competitor (Fig.…”

“…The linear partitioning coefficient (K d ) of carbamazepine was 1.7 and 12.3 l kg −1 . Sorption of bisphenol A on soils, sediments, minerals and zeolite was reported by Pan et al (2009). The K d data varied widely for bisphenol A from 2.75 to 212.8 depending on the properties of the solid matrices.…”

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.

“…These chemicals are released into soil, aquatic, and groundwater environments from many sources, such as livestock production and discharges from hospitals and pharmaceutical plants [1,2]. The environmental fate and transport of these emerging contaminants have received much attention [3,4]. Nonetheless, although numerous studies have been conducted to understand the fate processes of antibiotics in soil [5] and aquatic environments [6,7], to date very little information is available on the transport of antibiotics in groundwater environments [1].…”

Humic acid‐mediated transport of tetracycline and pyrene in saturated porous media

The authors observed that humic acid (HA) mediates transport of tetracycline and pyrene in saturated porous media via distinctively different mechanisms. The presence of HA (20-80 mg C/L) in the influent consistently enhances the transport of tetracycline, whereas for pyrene a critical HA concentration exists (about 10 mg C/L), below which transport is inhibited but above which transport is enhanced. The difference in the HA effect stems from the difference in relative sorption affinity to HA and sand between these two compounds. Because sorption of pyrene is driven primarily by hydrophobic effect, pyrene exhibits much stronger sorption to HA than on sand. Accordingly, pyrene in the influent (or mobile phase) is predominantly associated with HA, and its transport is controlled by the partition of HA between mobile phase and sand. For the polar, ionic, and highly hydrophilic tetracycline, sorption is driven mainly by surface complexation and ligand exchange, so tetracycline exhibits relatively strong adsorption on sand, but has much weaker sorption to HA than pyrene does. For tetracycline, the effect of HA on transport is likely the competition of HA for the available adsorption sites on sand. In addition, tetracycline and pyrene exhibit markedly different breakthrough profiles, both in the presence and in the absence of HA; this can be attributed to the greater degree of adsorption nonequilibrium of tetracycline on sand.
