ClearOccurrence and identification of microplastics in tap water from China
Researchers analyzed 38 tap water samples from cities across China and found microplastics in all of them, with concentrations averaging around 440 particles per liter. Most particles were smaller than 50 micrometers, and the dominant types were polyethylene and polypropylene fragments. The findings highlight that drinking water treatment plants face a significant challenge in addressing microplastic contamination in the water supply.
Occurrence of Microplastics in Tap and Bottled Water: Current Knowledge
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 of microplastics in tap and bottled water, and food packaging: A narrative review on current knowledge
This narrative review compiled findings on microplastic contamination in tap water, bottled water, and food packaging. Researchers found that various types of microplastic fragments have been detected in drinking water sources worldwide, with bottled water generally containing more particles than tap water. The review highlights that food packaging is an additional source of daily microplastic exposure, underscoring the need for better monitoring and regulation.
Prevalence and implications of microplastics in potable water system: An update
This review summarizes current knowledge on microplastic contamination in drinking water systems worldwide, covering sources, detection methods, and potential health implications. Researchers found that microplastics are present in both tap and bottled water, with fibers and fragments being the most common types detected. The study highlights the need for standardized testing methods and regulatory limits to protect public health from microplastic exposure through drinking water.
Analytical Review of Microplastics Occurrence in Bottled Water, Tap Water, and Wastewater Treatment Plants
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.
Microplastic Contamination in Drinking Water: A Review
This review summarized current research on microplastic contamination in drinking water, covering detection methods, occurrence data, and health implications. The authors found microplastics widely present in tap and bottled water worldwide and noted that conventional treatment processes remove them incompletely, raising ongoing concerns about chronic low-level human ingestion.
First evidence of microplastics and their characterization in bottled drinking water from a developing country
Scientists in a developing country analyzed 10 brands of bottled drinking water and found microplastics in all samples, with concentrations varying by brand. The most common particles were polyethylene and polypropylene fragments and fibers, likely originating from the plastic bottle caps and packaging. This study adds to evidence that bottled water is a significant source of daily microplastic intake for people worldwide.
Ubiquity of Microplastics in Drinking Water: An Update on Its Assessment and Impact
This review documents the widespread presence of microplastics in drinking water worldwide — including both tap and bottled water — and examines the potential health impacts of ingesting these particles. Current evidence shows microplastics are present in essentially all drinking water supplies at levels that cause concern, though the long-term health effects remain under investigation. The review calls for improved water treatment and reduced plastic use as parallel strategies to address the problem.
Microplastic pollution in drinking water
This review examines what is known about microplastic contamination in both tap and bottled drinking water around the world. Researchers found that while microplastics have been detected in drinking water at many locations, the reported concentrations vary enormously, making it difficult to draw firm conclusions about relative risk. The study highlights the urgent need for standardized sampling and analysis methods to produce reliable and comparable data on microplastics in the water we drink.
Occurrence and Source of Microplastics Contamination in Drinking Water and Performance of Water Treatment Plants in Removing Microplastics
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.
Estimated exposure to microplastics through national and local brands of bottled water in Central India
Researchers tested bottled water from national and local brands in central India and found microplastics in every single sample, with local brands containing about three times more than national brands. The most common particles were polyethylene and PET fragments, likely coming from the plastic bottles and caps themselves. The study estimated that people drinking bottled water in India could be consuming tens of thousands of microplastic particles per year, highlighting bottled water as a significant source of human exposure.
Occurrence and characterization of microplastics in bottled drinking water
Researchers analyzed microplastics in ten bottled water brands and found up to nine microplastic particles per liter, estimating that people who drink only bottled water may ingest over 150 microplastic particles per year — with polypropylene and polystyrene being the most common types found.
Microplastics in Drinking Water: Assessing Occurrence and Potential Risks
This review paper examines how widespread microplastics are in drinking water — from rivers and lakes to groundwater — and what health risks this contamination may pose. The authors call for urgent research into how microplastics move through water treatment systems and ultimately reach taps, emphasizing that current sampling and analytical methods are inconsistent, making it hard to compare studies or set safety thresholds. For people drinking tap or bottled water daily, understanding and regulating this exposure pathway is a pressing public health priority.
Insights into human exposure to microplastics through drinking water: Current state of the science
This review analyzed 66 studies on microplastics in drinking water from 2018 to 2023 and found that tap water actually contained more microplastics on average (about 62 particles per liter) than bottled water (about 38 particles per liter). Most particles were small fragments and fibers made of common plastics like PET, polyethylene, and polypropylene. The researchers estimate that people ingest roughly 175 microplastic particles per day just from drinking water alone.
First assessment of occurrence, characteristics and human exposure of microplastics in bottled drinking water, Nepal
Researchers conducted the first assessment of microplastics in bottled drinking water from Nepal's mountain, hill, and Terai regions, finding microplastics in all 35 samples tested (mean 118 items/L), with fiber-shaped particles dominating at 71.76%, establishing a baseline for this developing-country context.
Microplastics in Our Waters: Insights from a Configurative Systematic Review of Water Bodies and Drinking Water Sources
This systematic review mapped microplastic contamination across rivers, lakes, seas, tap water, and bottled water worldwide. The findings show that microplastics are present in virtually every water source we rely on, with rivers being the most studied and polyethylene being the most commonly found plastic type.
Abundance and characteristics of microplastics in drinking water treatment plants, distribution systems, water from refill kiosks, tap waters and bottled waters
This review summarizes research on microplastic contamination across the entire drinking water supply chain, from treatment plants to tap water and bottled water.
