Summary: The release of organic compounds in the aquatic environment is a serious hazard due to their toxic, hydrophobic, and persistent nature, making the removal of these contaminants a major topic in environmental science research. Phytoremediation, using plants to clean up pollutants, is a crucial process, with endophytic bacteria playing a key role in contaminant removal. Understanding the mechanisms behind bacterial-plant interactions is essential for various biotechnological applications.

Summary: The study assessed the phytoremediation abilities of nine wetland plant species for neonicotinoids, finding that Cyperus alternifolius and Cyperus papyrus exhibited the best removal performance for all six neonicotinoids. The main removal processes were determined to be biodegradation and plant accumulation, with further research needed on the toxicity of neonicotinoids to plants and microorganisms and their metabolic pathways in wetland systems.

Summary: Consortium FIP autonomously degrades Orange 3R with a higher elimination rate than individual plant systems. The consortium expresses a variety of oxidoreductase enzymes during Orange 3R degradation, successfully mineralizing it into metabolites. Toxicity assessment on the HepG2 cell line showed a reduction in the toxic nature of Orange 3R after phyto-treatment with consortium FIP.

Summary: The study showed that Scirpus grossus plants were effective in removing TSS from palm oil mill effluent, with a higher removal rate in the free-surface system compared to the sub-surface system on day 7. The presence of suspended solids in the effluent influenced the sedimentation rate, impacting TSS removal efficiency. COD removal was not significantly different between systems or with or without plants, indicating the importance of the sand medium in COD removal.

Summary: Anthropogenic activities produce a significant amount of organic pollutants that impact human health and the environment. While monitoring of many hazardous contaminants is regulated by law, certain substances like therapeutic agents and personal care products are not currently covered. Traditional methods of organic pollutant removal can be economically challenging, leading to the exploration of biological agents like phytoremediation, which uses plants for in situ decontamination. However, limitations such as plants' accumulation capacity, sensitivity to high concentrations of pollutants, and inability to utilize pollutants for growth, have led to the recent use of an integrated technology involving bacteria-assisted phytoremediation for enhanced efficiency.

Summary: Water scarcity is a major global challenge impacting food safety, food security, and human health. This study explored the potential of using vertical flow constructed wetlands (VF-CWs) with different indigenous wetland plants to treat chromium (Cr)-contaminated water. The results showed that VF-CWs vegetated with certain wetland plants can effectively remove Cr from water, with removal rates ranging from 47% to 92%. The wetland plants also accumulated Cr, with higher concentrations found in the roots. This research provides evidence supporting the use of VF-CWs with indigenous wetland plants as a sustainable technology for treating Cr-contaminated water.

Summary: The performance of different macrophytes in floating treatment wetlands (FTWs) for the remediation of ciprofloxacin (CIP) contaminated water is investigated in this study. The FTWs have the potential to remove 30-43.58 mg L-1 CIP from water in 28 days, and also reduce the chemical oxygen demand and biochemical oxygen demand of water. Among the macrophytes, Canna indica is the most effective in removing CIP, while Typha domingensis is the least effective. This study contributes to the sustainable bioremediation of water contaminated with antibiotics.

Summary: This study investigated the distribution, speciation, hydrogeochemical behavior and environmental risks of chromium in tannery wastewater in Kasur district, Punjab, Pakistan. The concentration of chromium was higher in winter compared to summer, and exceeded the national environmental quality standard. The presence of chromium was mainly in the form of hexavalent and trivalent chromium, controlled by iron and magnesium minerals. Environmental risk assessment categorized the tannery wastewater as 'worst quality' and unsuitable for crop irrigation without treatment.
