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.
A narrative review was carried out to describe the current knowledge related to the occurrence of MPs in drinking water. The reviewed studies (n = 21) showed the presence of microplastics (MPs) in tap (TW) and bottled (BW) water, increasing concerns for public health due to the possible toxicity associated with their polymeric composition, additives, and other compounds or microorganism adsorbed on their surface. The MP concentration increase by decreasing particles size and was higher in BW than in TW. Among BW, reusable PET and glass bottles showed a higher MP contamination than other packages. The lower MP abundance in TW than in natural sources indicates a high removal rate of MPs in drinking water treatment plants. This evidence should encourage the consumers to drink TW instead of BW, in order to limit their exposure to MPS and produce less plastic waste. The high variability in the results makes it difficult to compare the findings of different studies and build up a general hypothesis on human health risk. A globally shared protocol is needed to harmonize results also in view of the monitoring plans for the emerging contaminants, including MPs, introduced by the new European regulation.

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.
Occurrence of microplastics in tap and bottled water, and food packaging: A narrative review on current knowledge
AI summary Read the abstract
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.

Global Microplastics Contamination in Bottled and Tap Water: Prevalence and Sources
AI summary Read the abstract
This review pulls together existing research showing that tiny plastic particles (microplastics) are showing up in both bottled and tap water—sometimes at levels over 10,000 particles per liter in bottled water alone. Bottled water tends to have more plastic fragments (likely from the packaging itself), while tap water has more plastic fibers, often picked up from pipes and treatment systems. Since we don't yet fully know the health effects of ingesting these particles, this widespread contamination is a reminder that avoiding plastic exposure entirely is nearly impossible right now, which is why scientists are pushing for better water treatment and plastic
