Constructed wetlands (CWs) utilizing macrophytes represent a sustainable and cost-effective approach for sewage treatment in developing regions. This pilot study evaluated the performance of selected macrophytes (Typha latifolia, Phragmites australis, and Canna indica) in a horizontal subsurface flow constructed wetland system for treating domestic sewage. The study was conducted over a 6-month period (March-August 2024) with a hydraulic retention time of 3 days. Water quality parameters including biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), total nitrogen (TN), total phosphorus (TP), and fecal coliforms were monitored bi-weekly. Results demonstrated significant removal efficiencies: BOD (82- 89%), COD (76-84%), TSS (85-92%), TN (68-75%), and TP (71-79%). Typha latifolia exhibited the highest overall performance with superior nutrient uptake capacity and biomass production (2.8 kg/m²). Plant growth rates and physiological responses were monitored to assess stress tolerance and adaptation. The findings suggest that macrophyte-based constructed wetlands can effectively treat domestic sewage, providing an eco-friendly alternative to conventional treatment systems, particularly suitable for small communities and rural areas with limited infrastructure.
Wildfires are increasingly frequent and severe globally, with profound impacts on ecosystems. While the effects of fire on aboveground communities are well-documented, less is known about the responses of belowground fauna. This comprehensive review synthesizes current knowledge on how wildfires affect soil-dwelling organisms across diverse landscapes. We examine the direct and indirect impacts of fire on various faunal groups, including microarthropods, nematodes, and earthworms, and explore how landscape variability influences these effects. The review highlights the complex interplay between fire intensity, soil properties, and faunal community composition. We discuss the implications of these findings for ecosystem recovery and resilience, and identify critical knowledge gaps to guide future research. Understanding the responses of belowground communities to wildfire is crucial for developing effective post-fire management strategies and predicting long-term ecosystem changes in a warming world.
Constructed wetlands (CWs) offer a sustainable method for treating nutrient-rich rice mill wastewater while enabling biomass valorization. This study uses Life Cycle Assessment (LCA) to compare two castor-based CW models—for biodiesel and eri-silk cocoon production—across key impact categories such as human health, ecosystem quality, resource use, energy, water footprint, and compost sustainability.
Environmental pollution has become a major global concern, requiring innovative technologies for effective remediation. This review discusses recent advancements in environmental cleaning, including bioremediation, nanotechnology, advanced oxidation processes (AOPs), artificial intelligence (AI), green chemistry, and membrane filtration techniques. These technologies offer sustainable solutions for treating soil, water, and air pollution. This paper provides a comprehensive evaluation of their mechanisms, applications, advantages, limitations, and future potential. The integration of multiple technologies for enhanced efficiency is also examined, emphasizing the need for further research and policy development for large-scale implementation.
Dance is undoubtedly a great health exercise which needs a healthy body. Dancers have a unique perspective on the relationship between the body and the natural world, and their training and practice can lead to a deeper understanding of the environment. So a proper food system is required for the dancers. Staying in a polluted area, inhaling a high amount of CO² or such unhealthy gases will cause a risk for a dancer. So definitely we need a strong eco system and an interest in green technology. But what does the dance or dancer do for this? First of all, a dancer can spread awareness in society through their dance productions. Dance can be a powerful tool for raising environmental awareness by allowing audiences to experience the emotional and physical impact of environmental issues in a kinaesthetic way, fostering deeper understanding and connection to the problem.
