Summary: Phytofiltration is an eco-friendly and cost-effective approach to managing pollutants in aquatic systems. This study aimed to identify the process variables that determine the efficiency of invasive macrophytes in phytofiltration. Invasive macrophytes, such as Pistia stratiotes, pose challenges due to their unfettered proliferation, biomass generation, and nutrient uptake capability. However, these features make them ideal for decontaminating polluted aquatic systems.

Summary: The study found that the enteric pathogen S.Napoli can persistently adhere and internalize in aquatic plants, potentially serving as a reservoir of pathogens for humans and animals. The adhesion to roots and rhizomes, along with internalization, may play a significant role in bacterial persistence in aquatic ecosystems and transmission of pathogens.

Summary: The occurrence of aquatic vegetation in peat lakes is related to water depth, wind-fetch, nutrients, growth form, and life-history strategies. Different growth forms and overwintering strategies predict the occurrence of macrophytes in peat lakes, indicating the importance of environmental factors in species selection for re-vegetation efforts.

Summary: The research found that Salvinia natans and Pistia stratiotes have the ability to efficiently remove phosphorous from water bodies contaminated with high levels of nutrients, especially when the plants are P-starved. These aquatic macrophytes can potentially provide a green and sustainable solution for purifying water with excessive nutrients, such as wetlands, lagoons, and ponds.

Summary: In this study, the capacity of Lemna minor and Salvinia molesta to remove antibiotics from contaminated water was investigated. It was found that both plants were able to uptake Ciprofloxacin and sulfamethoxazole, with the mixed culture showing better removal efficiency than monoculture. S. molesta exhibited higher uptake capacity for antibiotics. These findings suggest that the use of L. minor and S. molesta in artificial wetlands can enhance the phytoremediation capacity of the systems.

Summary: Water pollution, including the use of plant protection products, is a significant environmental issue. Some plants have developed an efficient antioxidative system to cope with the pollution, and local plants can enhance the remediation process of polluted water ecosystems. The study found that toxic compounds can impact enzyme activities, and water mint showed the strongest response in terms of glutathione S-transferase activity.

Summary: The study investigated the influence of chlorpyrifos on the nonenzymatic system in various aquatic plants. It was found that high concentrations of chlorpyrifos led to an increase in polyphenols and flavonoids in the plants, while the main assimilating pigments showed the opposite trend. The research suggests that aquatic plants develop a defensive mechanism against toxic insecticides through their nonenzymatic antioxidant systems, and the amount of low-molecular weight compounds depends on the pollutant concentration.

Summary: The phytoremediation of partially treated municipal solid waste (MSW) leachate using selected free floating and emergent macrophytes has been shown to improve the quality of leachate before discharge to the environment. Different dilutions of leachate had varying effects on the growth of different macrophytes, with certain species showing better phytoremediation capabilities than others. The results suggest that certain emergent macrophytes, such as Chrysopogon zizanioides, could be recommended as the best plant for remediation of partially treated MSW leachate.

Summary: The study focused on the rate of leaf litter degradation in the evergreen forests of Pampadum Shola National Park in southern Western Ghats, India. The results showed that the degradation rate of major polymers in leaf litter follows the order cellulose > hemicellulose > lignin, with a higher degradation rate in the initial stages of decomposition. Certain phytochemical compounds and functional groups present in the initial stage were degraded and a few daughter compounds were formed at the end of the experiment.

The environmental relationships of these blooms were studied, showing a positive correlation of Noctiluca scintillans and Gymnodinium wulfii with temperature, salinity, phosphate, and nitrate, while Guinardia delicatula displayed an affinity towards silicate and ammonia. The reduced copepod abundance was attributed to the toxic thin layer of dinoflagellate blooms.

Summary: In this study, pineapple waste was hydrolyzed into acidic and alkaline solutions and used for biohydrogen production with locally isolated bacterial strains. Bacillus altitudinis showed the highest biohydrogen yield of 836.33 +/- 48.02 mL H-2 from alkaline hydrolysate during the 96th hour of fermentation. Compared to acidic hydrolysates, alkaline hydrolysates exhibited a higher yield of hydrogen. The aim of this study was to convert waste biomass into energy by utilizing native bacterial communities' potential.

Summary: This study systematically investigated the health risks of exposure to particulate-bound metals of different sizes and analyzed their sources. The results showed that resuspensions of crustal and road dust were the main sources of metals, and industrial emissions and biomass/waste burning were the major contributors to health risks. Metal-contaminated food ingestion posed non-carcinogenic risks, while inhalation of carcinogenic metals increased the risk of cancer. The health risks associated with exposure to size-segregated airborne metals were within the tolerable level but exceeded the safe level of exposure.

Summary: A mechanistic model was developed to assess the removal efficiency of pollutants in a wetland system, particularly in oil sands process-affected water (OSPW). The model simulated wetland mechanisms of chemical removal and showed that sustained wetland treatment is feasible. It is a helpful tool to evaluate the feasibility of treatment systems and to assess trade-offs in wetland design and operation.

The results showed that the operational performance of STAs improved over time. There were notable differences among individual STAs, with the co-precipitation of phosphorus with calcium playing a critical role in one of the STAs. This highlights the complexity of phosphorus removal in STAs and the need for site-specific management strategies.

Summary: The biogeochemical response to different flow conditions within two parallel flow-ways in Everglades Stormwater Treatment Area (STA)-2 was studied. It was found that there was a gradual decrease in the total phosphorus (TP) concentration from inflow to outflow for both emergent aquatic vegetation (EAV) and submerged aquatic vegetation (SAV) dominated systems, with EAV showing a higher reduction rate. Significant increase in TP concentration was observed in the SAV system under no flow condition, possibly due to the production of particulate phosphorus (PP) through various mechanisms.
