Removal of Glyphosate in Agricultural Runoff Using Subsurface Constructed Wetlands in Monocultures and Polycultures of Tropical Plants

Processes, Journal Year: 2025, Volume and Issue: 13(3), P. 860 - 860

Published: March 14, 2025

Glyphosate (GLY) is the most widely used herbicide in agriculture worldwide, posing a significant contamination risk to rivers, lakes, wetlands, and soils. Its ultimate fate represents potential threat health of both terrestrial aquatic ecosystems. This study evaluated removal efficiency glyphosate conventional pollutants mesocosm-scale horizontal subsurface flow-constructed wetlands planted with Canna indica, Heliconia psittacorum, Alpinia purpurata runoff water contaminated glyphosate. Additionally, examined performances these species monoculture polyculture settings tropical ornamental plants. indica exhibited highest growth (up 160 cm) conditions, as well efficiencies for total nitrogen (TN), phosphorus (TP), phosphate (PO43⁻), achieving 91%, 93%, 98% removal, respectively. Polyculture systems demonstrated superior ammonium efficiency, reaching 94%. (>5 ppm after 40 days) psittacorum 200 were effective removal. can be effectively removed from environments through constructed species, offering sustainable approach mitigating bodies.

Spent Mushroom Substrate-Derived Biochar and Its Applications in Modern Agricultural Systems: An Extensive Overview

Life, Journal Year: 2025, Volume and Issue: 15(2), P. 317 - 317

Published: Feb. 18, 2025

Spent mushroom substrate (SMS), a nutrient-dense byproduct of cultivation, has emerged as promising feedstock for biochar production, offering sustainable solution to modern agricultural and environmental challenges. This review explores SMS properties, its conversion into biochar, various applications. Due lignocellulosic structure, high organic matter (OM), essential nutrients, is ideal pyrolysis, process that enhances biochar's porosity, nutrient retention, carbon stability. These properties improve soil fertility, water microbial activity, plant growth while also contributing climate change mitigation through sequestration. SMS-derived stands out superior benefits, including balanced pH, rich profile, the ability adsorb heavy metals, which mitigates contamination minimizes toxic risks in food chain. By enhancing cycling, moisture supports farming practices reduce chemical fertilizer use boost resilience. Beyond applications, effective wastewater treatment, mitigating diseases, improving cultivation substrates, thereby mycelial productivity. Economically, it cost-effective alternative due abundant availability inexpensive nature SMS. Nevertheless, challenges still exist, particularly optimizing production methods ensuring consistency influenced by variations pyrolysis conditions types. Advances technology are vital scaling up production. paper emphasizes transformative potential advocating integration circular economy frameworks systems. Recommendations future research policy support provided maximize ecological economic benefits fostering widespread adoption global strategies.

Passive Treatment of Acid Mine Drainage Effluents Using Constructed Wetlands: Case of an Abandoned Iron Mine, Morocco

Water, Journal Year: 2025, Volume and Issue: 17(5), P. 687 - 687

Published: Feb. 27, 2025

This study presents the effectiveness of two vertical subsurface flow (VF) constructed wetlands (CWs), one planted with Juncus effusus (PCW) and other unplanted (CCW), for remediation acid mine drainage (AMD) from Ouixane abandoned site located in Morocco. The VFs were fed highly acidic AMD (pH < 2.5) evaluated over a period 150 days. substrate was composed limestone, as neutralizing agent, river gravel, natural peat moss, goal promoting growth sulfate-reducing bacteria (SRB) metals precipitation. results showed that both successfully neutralized acidity, effluent pH values ranging 3.57 to 8.5, indicating effective alkalinization AMD. Significant differences (p 0.05) observed between metal removal rates CCW PCW, except Mn. Both types system exhibited similar efficiencies influent. metalloid follows: 99.9% vs. 99% Cr, 80% As, 96% 94 Zn, 99.94% Fe, 90% 81% Al. Microbial sulfate reduction increased 43% 50% by presence plants. Sediment analysis revealed primarily stable forms: Fe Zn mostly associated Fe-Mn oxides, while Mn Ni predominantly present carbonates. These observations indicate relative stability CWs’ sediment. highlights studied CWs, particularly those vegetation, remediation, emphasizing importance agents, plants, organic substrates treatment process.
