Antibiotics with significant environmental toxicity, e.g., tetracyclines (TCs), are often used in large quantities worldwide, with 50-80% of the applied dose ending up in the environment. This study aimed to investigate the effects of exposure to tetracycline hydrochloride (TC) and minocycline hydrochloride (MIN) on . Our research evaluated the phytotoxicity of the TCs by analyzing plant growth and biomass and evaluating assimilation pigment levels and fluorescence. The research was extended with the ability potential of duckweed as a tool for removing TCs from water/wastewater. The results demonstrated that both TCs influenced Ir, Iy, biomass, and photosynthetic efficiency. The uptake of TC and MIN by duckweed was proportional to the concentration in the growth medium. The TC was absorbed more readily, reaching up to 8.09 mg × g of dry weight (DW) at the highest concentration (19.2 mg × L), while MIN reached 6.01 mg × g of DW. As indicated, the consequences of the influence of TC on plants were slightly smaller, in comparison to MIN, while the plants could biosorb this drug, even at the lowest tested concentration. This study has shown that using plants for drug biosorption can be an effective standalone or complementary method for water and wastewater treatment.
具有显著环境毒性的抗生素，如四环素（TCs），在全球范围内被大量使用，其中 50-80%的应用剂量最终进入环境。本研究旨在探讨盐酸四环素（TC）和盐酸米诺环素（MIN）暴露对植物的影响。我们的研究通过分析植物生长和生物量以及评估同化色素水平和荧光来评估 TCs 的植物毒性。该研究扩展了浮萍作为从水/废水中去除 TCs 的工具的能力潜力。结果表明，两种 TCs 都影响 Ir、Iy、生物量和光合作用效率。浮萍对 TC 和 MIN 的吸收与生长介质中的浓度成正比。TC 更容易被吸收，在最高浓度（19.2 mg × L）时达到高达 8.09 mg × g 干重（DW），而 MIN 达到 6.01 mg × g DW。如所指出的，与 MIN 相比，TC 对植物的影响后果略小，而植物即使在最低测试浓度下也可以生物吸附这种药物。本研究表明，使用植物进行药物生物吸附可以是一种有效且独立或补充的水和废水处理方法。
