Analytical Review of Microplastics Occurrence in Bottled Water, Tap Water, and Wastewater Treatment Plants
AI summary Read the abstract
This review analyzes microplastic contamination across bottled water, tap water, and wastewater treatment plants using data from studies worldwide. Researchers found that microplastic levels in drinking water are closely tied to the water source and that packaging type significantly influences contamination, with glass bottles recommended over plastic. The study emphasizes the need for improved water treatment technologies and greater public awareness about microplastic exposure through drinking water.
Currently, water availability and accessibility have become more challenging due to population growth, development of industrial and agricultural activities, and the effects of climate change. Various types of pollutants released by human activities threaten water quality and availability. Microplastics and emerging contaminants are currently affecting water resources and posing a risk to human health. The present study reviews the available studies that analyzed the abundance, shape, and size of microplastics in water, including glass, plastic, reusable, recyclable, and beverage bottled water, tap water, and wastewater treatment plant (WWTP) influent and effluent. Analysis of the collected data allowed comparison of microplastic abundance in different packaging water bottles, tap water, and raw and treated water from WWTPs. The analysis results suggest that microplastics in drinking water are mainly associated with water sources. Therefore, more attention should be paid to water treatment and purification processes and technologies. The type of packaging is also a crucial parameter to consider when quantifying microplastics in drinking water, although the use of glass bottles is recommended to minimize the potential associated risk to humans and ensure safe consumption. Increasing public awareness and knowledge about waste separation, the potential risks of microplastics to human health, and the urgent need for behavioral change in the management of waste, mainly plastic objects, remain the main keys to reducing the number of plastics entering our environment and our bodies.

Occurrence of Microplastics in Tap and Bottled Water: Current Knowledge
AI summary Read the abstract
This review summarizes current research on microplastic contamination in both tap and bottled drinking water. Researchers found that microplastics are present in both water sources, with bottled water generally containing higher concentrations than tap water, and smaller particles being more abundant. The study raises public health concerns and emphasizes the need for improved detection methods and drinking water treatment standards.
Occurrence and Source of Microplastics Contamination in Drinking Water and Performance of Water Treatment Plants in Removing Microplastics
AI summary Read the abstract
This review summarizes evidence that microplastics are present in both tap water and bottled water worldwide, with bottled water frequently contaminated by particles shed from the plastic packaging itself. Conventional water treatment plants remove between 40% and 93% of microplastics but cannot eliminate them entirely, meaning treated drinking water still carries measurable plastic loads. The chapter highlights the irony that plastic packaging intended to deliver clean water is itself a major source of microplastic contamination.
