Pharmaceuticals enter aquatic systems mainly with wastewater via wastewater treatment plants. These emerging contaminants can be removed by introducing biological cleaning systems with plants that grow near secondary wastewater units. This study analyzed the ability of <em>Lemna minor</em> to bioaccumulate four antidepressants: sertraline (SER), fluoxetine (FLU), paroxetine (PAR), and mianserin (MNS). A significant decrease in drug concentrations was observed in the samples with <em>L. minor</em> in comparison with those without plants. Among the tested drugs, <em>L. minor</em> showed the greatest bioaccumulation potential for SER, and the lowest for FLU. The bioconcentration factor for MNS never exceeded 100 L kg<sup>–1</sup> even after 7 days, while for SER it was 1,902 L kg<sup>–1</sup>. These results indicate that <em>L. minor</em> can influence the water treatment process in the natural ecosystem and serve as an effective tool in wastewater treatment for the removal of the analyzed antidepressants.</p></div>","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139538013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was carried out in channels with and without bed load, simulating conditions in a lowland river. The system was supplemented with artificial sewage containing FPOM and polypropylene fibres. Changes in the amount of suspended solids in the water, as well as organic matter and microplastics in the water and sediment, were recorded over the course of a week. The presence of a bed load increased the rate of suspension removal from the river water many times over. The decomposition rate of organic matter in the sediment was much higher than in the water, reaching 1 g of organic carbon per week. Bed load favoured the immobilisation of large microplastic fibres, facilitating their incorporation into bottom biofilms. The fibres formed a 'skeleton' that led to the formation of larger bed load biofilms.

The accelerated decomposition of peat formations in the Supraśl River catchment after heavy rains makes it easier for organic matter to penetrate into the aquatic ecosystem. Intensive flushing of valley and river bed sediments during summer floods has a particularly negative impact on the ecosystem of inland waters. If there are organic sediments on the bottom, their re-suspension is very dangerous. Then there is the immediate demand for oxygen, which can lead to deoxygenation of the water.
