Qualitative and Quantitative Analyses of Microplastics in Tap Water Supply Network in Iran
AI summary Read the abstract
Researchers analyzed tap water samples from the drinking water distribution system in Isfahan, Iran, and found microplastics present in all samples tested. The most common types were fibers made of polyethylene and polypropylene, with concentrations varying across different points in the distribution network. The study estimates human microplastic exposure from tap water consumption in the region and highlights the need for improved water treatment to address this emerging contaminant.
Background: Microplastics (MPs) exposure can affect humans in various ways, with tap water being one of the potential sources. Microplastics can absorb other pollutants and pose risks to both humans and the environment. Objectives: The aim of this study was to investigate the presence of MPs in tap water from the drinking water distribution system of Isfahan, Iran, and to determine the exposure to MPs from drinking tap water. Methods: Samples were collected from different points in the drinking water distribution system of Isfahan, Iran. Samples were prepared for analysis through filtration and chemical digestion. The MPs were counted using a scanning electron microscope (SEM), and the composition of MPs was analyzed using a micro-Raman spectrometer. Results: The concentration of MPs in tap water was found to be 287.0 ± 65.9 MPs/l. MPs ≤ 10 µm were the predominant sizes, and fibers were the predominant shape. Polyethylene terephthalate, polyethylene, and polypropylene were the most frequently identified MPs, respectively. Conclusions: Considering that the Iranian population consumes 7 - 15 liters of water daily for drinking and cooking, it is estimated that the average intake of MPs through cooking and drinking water is 2009 - 43,051 particles per day.

Microplastic contamination in drinking water sources and distribution networks of a Western City in Iran
AI summary Read the abstract
Researchers testing tap water in an Iranian city found tiny plastic fibers in every sample, with levels rising after rainfall—suggesting rain washes plastic particles into groundwater supplies. While the amounts detected were classified as low-risk based on current science, this study adds to growing evidence that microplastics are a routine, hard-to-avoid part of our drinking water, underscoring the need for better filtration and more research into long-term health effects.

Researchers identified microplastics in three conventional drinking water treatment plants in Tehran, Iran, finding that standard treatment processes do not fully eliminate particles down to 1 micron in size, raising concerns about microplastic exposure through tap water.
Identification of Microplastics in Conventional Drinking Water Treatment Plants in Tehran, Iran
AI summary Read the abstract
Researchers investigated microplastic occurrence at multiple treatment stages in three conventional drinking water treatment plants in Tehran, Iran, finding microplastics at all stages including in finished drinking water. The study confirms that conventional treatment processes do not fully remove microplastics from drinking water, creating a direct route of human exposure through tap water consumption.
Tracking microplastics contamination in drinking water in Zahedan, Iran: From source to consumption taps
AI summary Read the abstract
Researchers tracked microplastic contamination through the entire drinking water system in Zahedan, Iran, from raw water sources to household taps. While water treatment plants removed 64-75% of microplastics, tap water actually contained more microplastics than the treated water, likely due to contamination from pipes and plumbing. Children were estimated to consume more microplastics per body weight than adults, highlighting concerns about drinking water as a source of microplastic exposure.
Microplastics in urban water systems, Tehran Metropolitan, Iran
AI summary Read the abstract
Researchers investigated microplastic contamination across Tehran's urban water systems, including runoff, drinking water, groundwater, rivers, and wastewater effluent. They found microplastics present in all parts of the system, with residential and commercial runoff showing the highest concentrations. The study revealed that different land use types influenced the amount and characteristics of microplastic pollution, suggesting that urbanization patterns play a significant role in water contamination.
