Migration and remediation of typical contaminants in soil and groundwater: A state of art review

Land Degradation and Development, Год журнала: 2024, Номер 35(8), С. 2700 - 2715

Опубликована: Апрель 3, 2024

Abstract Soil and groundwater contamination has always been a global concern. Contaminants are migrated transformed in the soil environments, which turn pose potential environmental risks to humans. This paper describes four typical contaminants, including heavy metals, polycyclic aromatic hydrocarbons, microplastics, perfluorinated polyfluoroalkyl substances. Based on systematic summary of sources, hazards, migration behaviors these various existing remediation methods analyzed, advantages disadvantages different discussed. Finally, future research prospects described, significance study contaminant subsurface environment is emphasized. can help provide theoretical technical support for removal further improve rate actual sites.

Phytotoxicity and phytoremediation potential of Lemna minor exposed to perfluorooctanoic acid

Frontiers in Plant Science, Год журнала: 2025, Номер 15

Perfluorooctanoic acid (PFOA) is one of the highly toxic compounds which was phased out application in consumer products 2015 due to its harmful effects on human and environmental health. However, this chemical use for many years still found water resources. This study focuses physiological response duckweed ( Lemna mino r) exposed PFOA so as determine phytotoxicity potential aquatic species remove from environment. A time-dependent assay showed that exposure 0.1 µg/L 14 days resulted loss chlorophyll pigment 15-25% more chlorosis than controls. Although seven chlorosis, no significant impact parameters such photosynthetic or anthocyanin content were detected. The analysis cellular size day zero experiment control group significantly larger cell after (213 ± 6.5 µm²) compared with (186 18 µm²), while (198 13 did not change group. nuclear increased by 13% upon controls (ρ < 0.0001). concentration essential elements K, Cu, Fe, Mn, Zn, Mo reduced L. minor 39.6, 33.4, 42.1, 35.2, 31.9, 40.2%, respectively. Additionally, accumulated fronds roots an average bioaccumulation factor 56 7. Overall, some symptoms toxicity observed, shows can tolerate up PFOA, a commonly concentrations bodies, water. provides invaluable information regarding phototoxicity impacts phytoremediation PFOA.

Long-term management of PFAS contaminated water using constructed floating wetlands: Opportunities, limitations, and implementation considerations

Critical Reviews in Environmental Science and Technology, Год журнала: 2024, Номер unknown, С. 1 - 25

Опубликована: Июнь 7, 2024

This review critically examines the long-term management of per- and polyfluoroalkyl substances (PFAS) using constructed floating wetlands (CFW) as a sustainable approach for contaminated water treatment. PFAS, which are persistent widely distributed environmental contaminants, pose significant challenges due to their resistance natural degradation. CFW, featuring buoyant platforms that support vegetation, show promise in mitigating PFAS contamination through range processes such plant uptake, sorption growth media, accumulation biofilms. The explores CFW opportunities, emphasizing suitability installation existing urban environments with minimal earthwork drainage adjustments address contamination. It also assesses limitations, potential trophic transfer, highlighting need comprehensive studies on fate transport within these systems. To ensure efficiency management, highlights importance site-specific assessments, including species selection, hydrodynamics, PFAS-microbial community interactions. synergistic removal approaches, combining wetland plants' phytoremediation capabilities removable sorptive materials or other substrates discussed. Over-all, study provides valuable insights into covering essential implementation considerations achieving sustainable,
