ClearWetland Removal Mechanisms for Emerging Contaminants
This review examines how natural and constructed wetlands remove emerging contaminants, including pharmaceuticals, personal care products, and microplastics, from water.

The study highlights wetlands as a promising, low-cost approach for treating emerging contaminants that conventional wastewater systems may miss.
Constructed wetlands for emerging pollutants removal: A decade of advances and future directions (2014–2024)
This review evaluates a decade of research on constructed wetlands, an eco-friendly water treatment approach, for removing emerging pollutants including antibiotics and microplastics. The evidence shows that constructed wetlands can effectively remove many types of pharmaceuticals and microplastics from water through a combination of physical filtration, microbial breakdown, and plant uptake. These low-cost, nature-based systems could help reduce human exposure to microplastics in treated water, though optimizing their design for different pollutant types remains a challenge.
