Microplastics in Freshwater and Drinking Water: Sources, Impacts, Detection, and Removal Strategies
AI summary Read the abstract
Researchers review how microplastics enter drinking water systems and evaluate the limited ability of conventional treatment plants to remove them, underscoring a critical gap in public health protection given that most people worldwide consume tap water processed by these facilities.
The discovery of microplastics in freshwater and drinking water sources has raised concerns about the effectiveness of drinking water treatment facilities in protecting the public from exposure to these potentially harmful particles. Microplastics present in drinking water pose a risk to human health, and there is currently a lack of scientific knowledge about their existence and removal in drinking water treatment plants (DWTPs). It is crucial to understand the fate of microplastics in DWTPs as they act as a barrier preventing them from accessing drinking water. The manuscript focuses on the increasing concern of microplastics in freshwater environments, their sources, occurrence, and potential impacts on human health and aquatic ecosystems. The article discusses various techniques used for the detection, characterization, and quantification of microplastics in water. The text also covers the potential negative impacts of microplastics on the environment and human health, and the processes that drinking water treatment plants can use to eliminate microplastics from water. It emphasizes the importance of considering various parameters while implementing treatment strategies and highlights the effectiveness of ozone and UV treatments in speeding up the removal of microplastics. The paper also mentions the use of machine learning techniques for identifying and quantifying the environmental risks of microplastics and aiding in the development of new removal techniques. The article concludes by highlighting the need for regulations for the disposal and usage of microplastics and the importance of developing effective waste management strategies to reduce plastic consumption.

Occurrence and Fate of Microplastics in Freshwater Resources
AI summary Read the abstract
Microplastics enter freshwater resources through both primary sources such as cosmetic microbeads and secondary fragmentation of larger plastic debris, accumulating throughout river systems, lakes, and groundwater. Their persistence and widespread distribution in freshwater raise direct concerns for human exposure via drinking water consumption.
Freshwater Microplastic Pollution: The State of Knowledge and Research
AI summary Read the abstract
Microplastics have been detected in freshwater ecosystems worldwide, including in remote regions far from industrial activity, yet scientific understanding of their distribution, transport mechanisms, and biological impacts in rivers and lakes remains limited. Filling this knowledge gap is urgent because freshwater systems are primary sources of drinking water and support food webs directly connected to human health.
