Summary: The study assessed the sediment toxicity and pollution in the Shadegan International Wetland and the phytoremediation capability of Typha latifolia L. The results showed higher concentrations of toxic elements in the sediment, roots, and stems of Typha latifolia L. compared to the local background, indicating anthropogenic sources of pollution. The wetland was found to be moderately-heavily polluted and moderately to highly toxic. However, the toxicity towards organisms was at a medium-low level based on sediment quality guidelines. Typha latifolia L. showed potential for phytoremediation, particularly for Pb and Zn accumulation, and its phytoremediation capability increased with distance from the landfill area.

Summary: The study in Bahmanshir River of Iran revealed that sediment contamination was primarily caused by municipal wastewater/vehicular pollution, with contributions from weathering/industrial/agricultural activities. Moderate pollution levels for Pb and Cu were indicated, along with low to moderate contamination and toxicity overall. Typha latifolia L. demonstrated good phytostabilization capability for Cd, Cu, and Pb, and phytoextraction capacity for Zn, making it a potential candidate for bioaccumulation in the study area.

Summary: This study aimed to evaluate sediment pollution loadings and ecological risks, with three objectives. Through hierarchical clustering and principal component analysis, it was found that wetlands are most affected during the post-monsoon season, with most sites falling under moderate risk category. Cd was identified as the primary contributor to ecological risk. Chemical speciation analyses revealed different heavy metals' availability forms in sediment, highlighting the negative impact of Cr, Mn, and Mg on aquatic ecology.

Summary: Heavy metal pollution is a global concern, and phytoremediation using plants and associated microorganisms has been effective in removing heavy metals from contaminated sites. The Typha genus is particularly suitable for phytoremediation because of its rapid growth, high biomass production, and ability to accumulate heavy metals. Plant growth-promoting rhizobacteria have also been studied for their ability to improve plant growth and tolerance to heavy metals. This review discusses the phytoremediation process, the application of Typha species, and the bacterial communities associated with their roots in both contaminated and non-contaminated environments, highlighting the importance of Proteobacteria in these communities.

Summary: The study found that water depth and inundation duration have an impact on the growth and health of Typha domingensis. Deeper water treatments resulted in lower Typha density, but significantly affected the density of juveniles and leaf elongation rate. Typha adapted to deep water conditions by changing its morphology and biomass allocation to enhance gas exchange between above and belowground tissues.

Summary: This study investigated the effect of different measures on the rotation of rape-kenaf and rape-sweet sorghum in polluted farmland. The results showed that the rotation systems coupled with specific measures greatly increased crop yield and enhanced the uptake of Cd and Pb, effectively accelerating phytoremediation. The rotation systems also met safety standards for food and forage, and demonstrated economic value.

Summary: Cadmium is a harmful heavy metal that can cause environmental and health hazards through the food chain. Various biological approaches, particularly using microbes, have shown potential for remediating Cd contamination in natural resources. Studies have also demonstrated the effectiveness of heavy metal resistant microbes as biosorbents for removing Cd from natural resources.

Summary: This study aimed to isolate lead- and cadmium-tolerant endophytic bacteria from the roots of Typha latifolia growing in heavy-metal-contaminated environments. Several bacterial isolates with biochemical activities were identified, which could promote the growth of T. latifolia seedlings and help them adapt to the polluted site.

Summary: In this study, a two-stage enzymatic hydrolysis process using Typha domingensis as the source material achieved enhanced glucose production compared to a single-stage approach. The optimized process reached glucose yields of 74.4% and 71.7% for starch and cellulose fractions, respectively, demonstrating the importance of considering key process variables for increasing glucose production.

Summary: This study assessed metal contamination in mudflat sediment cores from different regions of the Chapora Estuary. The results showed variations in metal concentrations within the sediments, which were influenced by hydrodynamics, metal sources, and sand mining. The enrichment factor and geo-accumulation index indicated moderate contamination of manganese, while the potential contamination index revealed moderate contamination of iron, manganese, copper, cobalt, and nickel in certain regions. The study also found that metals were closely associated with iron-manganese oxides and organic/sulfide fractions, which influenced their bioavailability. Manganese, nickel, and zinc in Saccostrea cucullata exceeded permissible limits, indicating their toxicity and unsuitability for human consumption.

Summary: Floating treatment wetlands (FTWs) are a cost-effective ecological engineering tool for the restoration of polluted water bodies. This study evaluated the efficiency of FTWs planted with Typha domingensis in removing both Cr(III) and Cr(VI). The results showed that both Cr species were efficiently removed from water in all treatments, with T. domingensis directly involved in Cr removal. Cr was mainly bound to organic matter in sediments, indicating a low risk of future release under FTW conditions. T. domingensis demonstrated tolerance to both Cr species, with Cr mainly accumulated in the roots.

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.

Summary: This study examined the long-term phosphorus retention in Stormwater Treatment Areas (STAs) and identified the factors influencing their performance. 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.
