Summary: This study reviewed the research on enhanced constructed wetlands (CWs) for the removal of heavy metals and metalloids (HMMs) from polluted water. A bibliometric analysis was performed to evaluate research trends, critical literature, and keyword evolution. The study found that research on CW technology for the remediation of HMM-polluted water is receiving increased attention, with no apparent trends in topics. Suggestions for optimizing the design and operation of efficient CWs for HMM-polluted water treatment are proposed based on the established literature.

Summary: Constructed wetlands (CWs) are engineered systems that utilize natural processes for wastewater treatment. CWs take advantage of processes found in natural wetlands, but operate in a more controlled environment. They can be classified based on the presence/absence of wastewater on the wetland surface, and the direction of subsurface flow. Hybrid CWs combine different types of CW technologies. The use of CWs for wastewater treatment gained popularity in the 1990s and early 2000s due to stricter regulations and the application of CWs in circular economy concepts.

Summary: The combination of an organic amendment, biological treatment, and nZVI was shown to be the strategy of choice in soils with high concentrations of Cr(VI) and lindane, while for moderate levels of chromium, the organic amendment plus biological treatment is the most profitable treatment.

Summary: Increasing pollution caused by inappropriate anthropogenic activities and industrialization has raised concerns about general health. Bioremediation is considered as the most efficient, economical, and environmentally friendly method for treating polluted environments. Microorganisms play a crucial role in detoxifying harmful pollutants by degrading, mineralizing, and transforming them into less toxic forms. Different bioremediation techniques have their own advantages and limitations based on the characteristics and location of the pollution. This review analyzes various bioremediation methods for organic pollutants from soil/sediments and wastewater, and explores emerging technologies that can enhance the efficiency of bioremediation. The integration of these technologies with existing bioremediation facilities is changing the landscape of environmental remediation towards sustainability.

Summary: This study investigated the factors affecting N2O emissions from constructed wetlands and developed a statistical formula to estimate N2O emission factors (EFs). The application of the formula to Greek settlements predicted a significant reduction in N2O emissions if constructed wetlands were used instead of conventional wastewater treatment plants.

Summary: This study evaluates the use of bamboo species as an alternative in constructed wetlands for wastewater treatment through bibliometric analysis and case study review. The study reveals the potential benefits of using bamboos in wastewater treatment, such as hyperaccumulation capacity and bioproduct generation, and identifies other promising applications. Despite promising results, further research is needed to investigate the morphological functions of bamboos in wastewater treatment with landscape integration and resource recovery.

Summary: Bioaugmentation combined with biostimulation was more effective in enhancing the degradation of HCHs in contaminated soil compared to biostimulation alone. Simultaneous application of inorganic and organic nutrient substances improved the living environment of microorganisms and increased microbial quantities, accelerating the enzymatic reaction and degradation of HCHs.

Summary: In this study, melatonin was added to constructed wetland systems to investigate its effects on plant physiology, microbial enzyme activity, and microbial community structure. The results showed that melatonin treatment improved the stress tolerance and nutrient content of Phragmites australis plants, and increased the removal efficiency of NH4+-N in the constructed wetlands. Melatonin also altered the microbial composition and functions, leading to improved purification effect of the constructed wetland.

Summary: Reclamation of pesticide contaminated sites, especially agricultural soil and pesticide manufacturing sites, has been challenging. Microbial bioremediation is an ecofriendly strategy for soil reclamation, but its large-scale field application faces challenges due to the varying interaction of microbes with polluted soil under different climatic conditions. Addressing challenges and employing interdisciplinary approaches can make microbe assisted bioremediation the preferred method for reclamation of pesticide contaminated sites.

Summary: Rhizoremediation is a green and sustainable alternative for remediating contaminated environments by utilizing the symbiotic relationship between plants and their associated soil microorganisms. Identification of suitable plant-microbe combinations and application of appropriate soil amendments can enhance overall efficiency.

Summary: This study evaluated the effects of arbuscular mycorrhizal fungi (AMF) and different substrate types on the purification of pharmaceuticals and personal care products (PPCPs) in constructed wetlands. The results showed that adsorptive substrates (biochar, vermiculite, or perlite) had a greater impact on the removal of pollutants from wastewater than AMF symbiosis. Additionally, the presence of plants improved the performance of wetlands in wastewater purification.

Summary: This study examined the removal performance of organics and nutrients in intensified constructed wetlands, specifically tidal flow-based microbial fuel cell (MFC) and tidal flow wetlands receiving municipal wastewater. The results showed high removal rates for ammonia nitrogen, total nitrogen, phosphorus, chemical oxygen demand, and biochemical oxygen demand under different flood periods and media variations, with TN removal reaching the highest percentage under 24-h flood periods. Tidal flow-based MFC wetlands outperformed tidal flow wetlands in TN removal due to supplementary electron production through fuel cell-based organics degradation kinetics.

Summary: This study investigated the effects of bioaugmentation and biostimulation on the microbiomes and nitrate removal rates of woodchip bioreactors (WBRs). The results showed that introducing denitrifying bacteria and adding acetate can enhance the nitrate removal efficiency of WBRs. Additionally, the study found that denitrifiers are unevenly distributed in WBRs.

Summary: This study investigated the extractability, bioaccessibility, and biodegradation of 14C-phenanthrene and 14Coctacosane in two soils from former oil refinery facilities over 341 days. The impact of biostimulation and bioaugmentation treatments were evaluated, with bioaugmentation showing significant improvements in the degradation of 14C-octacosane residues. However, HPCD and methanol:water may underestimate the extent of contaminant degradation in soil.
