[en] Global studies of microplastic (MP) pollution confirm wastewater treatment plants serve as pathways for microplastics entering terrestrial and aquatic ecosystems. The behaviour, transport and fate of microplastics in wastewater effluents remain mostly unknown, rendering wastewater-derived microplastics as a contaminant of significant concern. We critically examine the literature to understand the sources and fate of microplastics in wastewater treatment plants (WWTPs) and the implications of treated effluents admitted to soil and aquatic systems. The transport of chemical and biological contaminants is also discussed in detail, using fundamental principles of vector relationships. For the removal and reduction of microplastics, profound knowledge is required from source to solution. This review presents a comprehensive overview of the significance of microplastics as a vector of water-borne contaminants in WWTPs.
[en] Aquatic or land-based plastic pollution has raised serious concerns for ecosystems, and especially human and animal health worldwide. A variety of legislative instruments were developed to control, reduce, and manage the usage of plastics in day-to-day life to minimize the adverse outcomes brought by sending these plastic to landfill. Existing legislation heavily embraces levies, bans, and voluntary efforts through “reduce and reuse campaigns.” Thus, the present review highlights the pros and cons of the existing legislation and its implementation. It also assesses the need for the improvement of plastic legislation to better consider environmental and human health impacts. The paper proposes new efficient management strategies to aid in the development of plastic legislation which prevents increase of plastic pollution worldwide, the potential challenges that would arise from its implementation, and the mechanisms for overcoming these challenges. The paper proposes a conventional management strategy based on the current plastic management and legislation. It aims to improve the feasibility and effectiveness of the implementation of future plastic policies.
