After quantification of 77 target antibiotics in 6 categories, ten antibiotics were detected simultaneously with a detection frequency &amp;gt;50.0% in water and sediment; the concentrations of these ten antibiotics were 0.1–1508.0&amp;nbsp;ng&amp;nbsp;L−1&amp;nbsp;and 0.01–9.4&amp;nbsp;ng&amp;nbsp;g−1&amp;nbsp;in water and dry sediment, respectively. Sulfadiazine and Azithromycin (Pseudo partitioning coefficient were 28–3814&amp;nbsp;L&amp;nbsp;kg−1&amp;nbsp;and 21–2405&amp;nbsp;L&amp;nbsp;kg−1, respectively.) had the largest partitioning coefficient between sediment and water. In addition, pseudo partitioning coefficient of Sulfadiazine and Clindamycin were higher than the values of corresponding equilibrium partitioning constant (&lt;em&gt;K&lt;/em&gt;d), which would likely cause them to re-release from sediment to water. Compared to the physiochemical properties of the sediment, water quality has a greater impact on antibiotic partitioning. We found that the partitioning of antibiotics was significantly positively correlated with&amp;nbsp;&lt;a class=&quot;topic-link&quot; href=&quot;https://www.sciencedirect.com/topics/earth-and-planetary-sciences/salinity&quot; title=&quot;Learn more about salinity from ScienceDirect&amp;#039;s AI-generated Topic Pages&quot;&gt;salinity&lt;/a&gt;, suspended solids, pH, NH4+-N and Zn; and negatively correlated with temperature, dissolved oxygen, PO43−,&amp;nbsp;&lt;a class=&quot;topic-link&quot; href=&quot;https://www.sciencedirect.com/topics/earth-and-planetary-sciences/chemical-oxygen-demand&quot; title=&quot;Learn more about chemical oxygen demand from ScienceDirect&amp;#039;s AI-generated Topic Pages&quot;&gt;chemical oxygen demand&lt;/a&gt;, NO3−-N, oil, Cu and Cd. The ecological risks of antibiotics in water and sediment were also evaluated for revealing their relationship with the concentration partitioning of antibiotics. Results showed that the target antibiotics mainly pose ecological risks to Daphnia with low and median chronic toxicity risk rather than fish and&amp;nbsp;&lt;a class=&quot;topic-link&quot; href=&quot;https://www.sciencedirect.com/topics/earth-and-planetary-sciences/green-alga&quot; title=&quot;Learn more about green algae from ScienceDirect&amp;#039;s AI-generated Topic Pages&quot;&gt;green algae&lt;/a&gt;. The antibiotics in sediment were more chronically toxic to Daphnia than that in water. The risk quotient ratio of sediment and water (RQs/RQw) ranged from 0 to 1154.0, which were exactly opposite of the values of&amp;nbsp;&lt;a class=&quot;topic-link&quot; href=&quot;https://www.sciencedirect.com/topics/earth-and-planetary-sciences/organic-carbon&quot; title=&quot;Learn more about organic carbon from ScienceDirect&amp;#039;s AI-generated Topic Pages&quot;&gt;organic carbon&lt;/a&gt;&amp;nbsp;normalized&amp;nbsp;&lt;a class=&quot;topic-link&quot; href=&quot;https://www.sciencedirect.com/topics/earth-and-planetary-sciences/partition-coefficient&quot; title=&quot;Learn more about partition coefficient from ScienceDirect&amp;#039;s AI-generated Topic Pages&quot;&gt;partition coefficient&lt;/a&gt;&amp;nbsp;(&lt;em&gt;K&lt;/em&gt;oc), suggesting that the physical properties of antibiotics drove the ecological risk allocation of antibiotics in sediment and water.</style></abstract></record></records></xml>
