Land application of sewage sludge as a pathway for emerging contaminants: a comparative review of microplastics, PFAS, and pharmaceuticals

Floating Treatment Wetlands for Emerging Contaminants in Wastewater: A Critical Review of Removal Mechanisms, Performance and Sustainability

Floating treatment wetlands (FTWs) are buoyant, vegetated treatment systems in which plant roots and associated biofilms develop directly within the water column. They are increasingly presented as low-energy, modular nature-based technologies for polishing wastewater and contaminated surface waters, yet their capacity...

PFAS Degradation Technologies and Mechanisms in Soil: A Review

Fate and persistence of emerging chemical contaminants after land application of biosolids: A screening-level risk assessment.

The presence of emerging chemical contaminants embodied in wastewater treatment plant residuals represents a potential barrier to the continued land application of biosolids given concerns about diffuse and long-term contamination of agricultural lands. Their diverse physiochemical properties, and uncertain environment...

Microplastic-Mediated Contaminant Mobilization and Biosystem Responses in Agricultural Soils

Plant Extracts for Heavy Metal Removal from Urban Wastewater: A Critical Review of Removal Mechanisms, Toxicity Reduction, and Implementation Constraints

Urban wastewater carries a persistent load of heavy metals from households, commercial activity, road runoff and small industries. Conventional treatment moves much of this load into sewage sludge, but a substantial fraction can remain in the treated effluent, which limits safe water reuse and the agricultural use of b...

A Critical Review of Microplastic Contamination in Agricultural Soils and its Potential Risks to Crops and Human Health

Microplastic contamination of agricultural soils has moved from a largely conceptual concern to an empirically documented component of terrestrial pollution. Agricultural plastic films, sewage sludge, compost and other organic amendments, irrigation water, atmospheric deposition, and diffuse litter can introduce plasti...
