Prevalence and implications of microplastics in potable water system: An update
AI summary Read the abstract
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.
Synthetic plastics, which are lightweight, durable, elastic, mouldable, cheap, and hydrophobic, were originally invented for human convenience. However, their non-biodegradability and continuous accumulation at an alarming rate as well as subsequent conversion into micro/nano plastic scale structures via mechanical and physio-chemical degradation pose significant threats to living beings, organisms, and the environment. Various minuscule forms of plastics detected in water, soil, and air are making their passage into living cells. High temperature and ambient humidity increase the degradation potential of plastic polymers photo-catalytically under sunlight or UV-B radiations. Microplastics (MPs) of polyethylene terephthalate, polyethylene, polystyrene, polypropylene, and polyvinyl chloride have been detected in bottled water. These microplastics are entering into the food chain cycle, causing serious harm to all living organisms. MPs entering into the food chain are usually inert in nature, possessing different sizes and shapes. Once they enter a cell or tissue, it causes mechanical damage, induces inflammation, disturbs metabolism, and even lead to necrosis. Various generation routes, types, impacts, identification, and treatment of microplastics entering the water bodies and getting associated with various pollutants are discussed in this review. It emphasizes potential detection techniques like pyrolysis, gas chromatography-mass spectrometry (GC-MS), micro-Raman spectroscopy, and fourier transform infrared spectroscopy (FT IR) spectroscopy for microplastics from water samples.

Ubiquity of Microplastics in Drinking Water: An Update on Its Assessment and Impact
AI summary Read the abstract
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
AI summary Read the abstract
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.
