Performance of Large-Scale Ornamental Wetlands for Municipal Wastewater Treatment: A Case Study in a Polluted Estuary in the Gulf of Mexico

Sustainability, Год журнала: 2025, Номер 17(5), С. 2120 - 2120

Опубликована: Март 1, 2025

This study investigates the performance of large-scale ornamental treatment wetlands (TW) for municipal wastewater in municipality Nautla, Veracruz, Mexico, specifically within a contaminated estuary Gulf Mexico. The research employed wetland system that integrates mixed flow methods, including vertical subsurface (VSSF) and horizontal (HSSF), to optimize operational, maintenance, energy costs. Over monitoring period from 15 October 2022 17 September 2023, achieved remarkable efficiencies removal chemical oxygen demand (COD), NH3-N, NH4-N, NO2-N, NO3-N, total nitrogen (TN), with rates 93.37%, 93.37%,91.36%, 91.29%, 95.74%, 97.36%, 71.69%, 92.26% 91.45%, respectively. effluent complied water quality standards established by official Mexican standard NOM-001-SEMARNAT-2021, demonstrating effectiveness this TW configuration treating characterized high demand, nitrogen, phosphorus levels. results are especially relevant tropical climates, where temperatures humidity can affect microbial activity nutrient cycling, potentially enhancing reducing construction management highlights viability as sustainable solution climates provides valuable information future implementation design criteria.

Carbon Cycling in Wetlands Under the Shadow of Microplastics: Challenges and Prospects

Toxics, Год журнала: 2025, Номер 13(3), С. 143 - 143

Wetlands are one of the most crucial ecosystems for regulating carbon sequestration and mitigating global climate change. However, disturbance to dynamics caused by microplastics (MPs) in wetlands cannot be overlooked. This review explores impacts MPs on cycles within wetland ecosystems, focusing underlying physicochemical microbial mechanisms. The accumulation sediments can severely destabilize plant root functions, disrupting water, nutrient, oxygen transport, thereby reducing biomass development. Although may temporarily enhance storage, they ultimately accelerate mineralization organic carbon, leading increased atmospheric dioxide emissions undermining long-term sequestration. A critical aspect this process involves shifts community structures driven selective colonization MPs, which affect decomposition methane production, thus posing a threat greenhouse gas emissions. Notably, dissolved matter derived from biodegradable promote photoaging coexisting enhancing release harmful substances aged further impacting microbial-associated due disrupted metabolic activity. Therefore, it is imperative deepen our understanding adverse effects mechanisms health cycles. Future strategies should incorporate regulation ecological engineering techniques develop effective methodologies aimed at maintaining sustainable capacity affected MP contamination.
