Summary: Aquaponics combines aquatic animals with hydroponic plants, with studies showing the great attributes of aquatic macrophytes for feeding different species. However, there is limited information on managing macrophytes in aquaponics. High flow rates and short HRTs contribute to the highest biomass production and plant growth, while planting density directly affects plant behavior. Retaining around 7-8% of nutrients in water by aquatic macrophytes can keep water quality within suitable limits for fish production.

Summary: The application of nanoparticles has been proved to be an efficient technique for mitigating stress in plants. In this study, the synergistic effect of iron oxide nanoparticles and silicon nanoparticles in alleviating cadmium toxicity in Phaseolus vulgaris was elucidated. The results showed that nanoparticles enhanced growth and gas exchange in Cd-contaminated plants, and the synergistic application of iron oxide nanoparticles and silicon nanoparticles increased potassium content and polyamine biosynthesis, alleviating cadmium stress.

Summary: This study explores the potential of acidifying cattle slurry to enable the growth of Lemna minor on less diluted wastewater, which is typically toxic to the plant. By lowering the pH, the toxic NH3 form can be shifted towards the less toxic NH4+ form, allowing the plant to grow. This finding has important implications for implementing duckweed-based wastewater treatment systems in agriculture.

Summary: This study investigated the effects of different concentrations of BPA on the growth, photosynthesis, antioxidant system, and osmotic substances of duckweed. The results showed that low concentrations of BPA promoted plant growth and improved the concentration of photosynthetic pigments, while high concentrations of BPA inhibited growth and photosynthesis. Additionally, high concentrations of BPA induced oxidative stress and activated the antioxidant defense system in the plants. These findings provide new insights into the effects of BPA on aquatic plant physiology.

Summary: The study suggests that Lumefantrine has adverse but variable effects on the growth and physiology of the studied aquatic plants, with a decline in growth for some species and stimulation in growth for others. This indicates that the pharmaceutical may have different impacts on various aquatic organisms.

Summary: This study evaluated the toxicity of heavy metals in textile and tannery wastewater and investigated the effect of acetic acid on the phytoextraction of heavy metals by duckweed plants. The results showed that the addition of acetic acid significantly improved the antioxidant defense mechanism in plants and alleviated the toxicity of heavy metals. Duckweed plants were found to be a potential phytoremediation option for industrial wastewater treatment.

Summary: Chromium (Cr) toxicity is a serious problem that negatively affects living organisms and agricultural production. The use of scandium (Sc) as an antioxidant enhancer has shown potential for mitigating the harmful effects of Cr toxicity in plants. This study investigated the effects of Sc treatments on Lemna minor exposed to Cr stress, and found that Sc increased antioxidant enzyme activities and hormone levels, while reducing oxidative damage and improving photosynthesis.

Summary: This study assessed the effect of light intensity on the phytoremediation potential of Lemna minor, finding that the response of Lemna minor to light intensity varied under different conditions. The interactive effects of light intensity and wastewater composition on growth and phytoremediation potential of Lemna minor were demonstrated, suggesting that high light intensities may not necessarily be beneficial in duckweed wastewater remediation.

Summary: Plastic pollution is a significant issue, and this study investigates the toxic effects of polystyrene nanoplastic on aquatic plants. The results suggest that low concentrations of nanoplastic do not cause oxidative damage or limitations in photosynthetic capacity, while high concentrations result in insufficient antioxidant activity and oxidative damage.

Summary: This study assessed the adverse effects of four pharmaceuticals and their binary mixtures on Lemna minor, revealing toxic effects for all tested substances with methotrexate being highly toxic. The most sensitive endpoints for binary mixtures were photosynthetic pigments and frond surface area. Synergistic effects were observed in mixtures of methotrexate with fluoxetine or 17 alpha-ethynylestradiol, while mostly additive effects were seen in mixtures with diclofenac. More chronic ecotoxicological data is needed to better understand the environmental risk of methotrexate in surface water.

Summary: The present study evaluated the potential of common duckweed as a source of bioactive compounds. Untargeted profiling of the bioactive components was done using UHPLC-HRMS, and in vitro antioxidant and enzymatic inhibition properties were assessed. The results showed that common duckweed is rich in carotenoids and flavonoids, with the highest correlation values to the bioactive properties. The optimized extraction parameters revealed that ethanol percentage has a pivotal impact on the recovery of bioactive compounds.

Summary: Silver nanoparticles (AgNPs) are commonly used in consumer products for their antimicrobial properties and can enter aquatic ecosystems through wastewater. This study investigated the toxicity of AgNPs and AgNO3 on Lemna minor at different initial frond densities. Results showed that plants at higher initial frond densities were more sensitive to silver, with lower growth rates observed in both silver treatments. Competition and crowding at high frond densities resulted in reduced growth in the presence of silver.

Summary: Soils contaminated with rare earth elements (REEs) can harm agriculture by causing physiological disorders in plants. This study investigated the impacts of different concentrations of nano terbium (Tb) on duckweed, revealing effects on ion and hormone accumulation, chlorophyll fluorescence, photochemical reactions, and antioxidant activity. At appropriate concentrations, Tb can enhance the antioxidant system, protect photosynthetic reactions, and regulate hormone levels in duckweed.
