“…This study did not count PAM in microplastics because it is water-soluble; however, in previous studies, PAM is regarded as microplastics in some drinking water [17,26]. Polytetrafluoroethylene (PTFE) was also detected in TW1 after passing through the DWTPs but not in RW1, indicating that the treatment process and pipeline contribute microplastics into the water [27]. At the same time, large amounts of chlorine-containing disinfectants are also widely used in DWTPs.…”

“…Among these studies investigating the change in microplastic abundance from water sources to consumed tap water [16,[22][23][24][25], only Bäuerlein et al have sampled RWs from different water bodies and found some differences in microplastic abundances [25]. Generally, the treatment processes in DWTPs aim to remove contaminants, such as turbidity, organic matter, and microorganisms, affording fresh drinkable water [26,27]. The water purification processes in DWTPs are not specially designed to remove microplastics, which are emerging global environmental pollutants; however, nontargeted microplastic removal often occurs after traditional sand filtration [27].…”

Microplastics in drinking water have attracted increasing global concerns due to their potential adverse impacts on human health. However, there needs to be more knowledge of the occurrence and distribution of microplastics in drinking water systems from water sources to household tap water. Herein, laser direct infrared spectroscopy is used to investigate the occurrence of microplastics in a typical drinking water plant with different water sources. Microplastic information is further used to understand microplastic fates during drinking water supply, including microplastic abundance, size, shape, and polymer type. Overall, the microplastic abundance in treated water ranges from 12.00 to 25.33 particles/L, higher than those in raw water (RW; 2.33–17.33 particles/L) and household water (HW; 8.00–19.67 particles/L), which shows that microplastics are not removed from RW. The main polymers in these microplastics are polyethylene terephthalate, polyvinyl chloride, polyethylene, and polypropylene. At the same time, the main microplastic shapes are fragments and fibers. Small-sized microplastics of 20–100 μm account for up to 76.74% and 79.30% of microplastics during the dry and wet seasons, respectively. Additionally, more microplastics are detected in RW from rivers than those from reservoirs and lakes, and the microplastic abundance in the wet season is higher than that in the dry season. As expected, the potential ecological risk of microplastics in all waters is the I level, which is the lowest level. Most importantly, the annual microplastic intake of an adult via drinking water is 5063–18,301 microplastics, less than that reported in previous studies. These results provide valuable data on the fates of microplastics in drinking water supply systems from water sources to HW and promote authorities to update the treatment technologies for drinking water in the future to remove microplastics efficiently.

“…Figuring out microplastics in consuming water is crucial because of the related health risks, such as the ability of Microplastics to carry dangerous chemicals and pathogens (Acarer et al, 2023). Accurate evaluation is important for assessing and mitigating these dangers (Koelmans et al,2019).…”

Plastic pollution is a critical environmental issue today, with microplastics emerging as persistent toxicants found in various samples. Recent studies have detected Microplastics in drinking water, raising concerns due to their association with toxicity in animals, including humans. Metagenomics has become instrumental in understanding the microbial communities responsible for plastic biodegradation. The text discusses the challenges associated with detecting and evaluating microplastics in drinking water, highlighting metagenomics as a viable instrument for devising enduring remedies for plastic contamination. There is a great deal of environmental concern due to the fact that microplastics pollution is pervasive and that it harms ecosystems and human health. Metagenomics, a powerful tool for studying microbial communities, has emerged as a promising approach for understanding the biodegradation of microplastics. This review explores how metagenomics helps identify the microbial communities that break down microplastics, showing promise in creating strategies to reduce microplastics pollution. It summarizes recent metagenomic research on microplastics, focusing on identifying important microbial groups and enzymes involved in degradation. Additionally, we discuss the challenges and future directions of using metagenomics to address microplastics pollution, emphasizing the need for interdisciplinary research efforts to develop sustainable solutions.

“…Microplastics represent a diverse group of emerging pollutants with varying structures, sizes, and densities, compounded by their inert properties, rendering them resistant to removal from water [40,41]. Existing water treatment systems exhibit variable efficacy in trapping microplastics, contingent upon factors such as size, nature, and technological sophistication [7,42]. A straightforward approach in drinking water treatment involves passing water through filter media, where the effectiveness of microplastic removal hinges on the pore size of the filter medium.…”

This study investigates the presence of microplastics in tap drinking water and evaluates the efficacy of various sorbents for their removal in the context of Kazakhstan’s water treatment system. Water samples taken in the cities of Kokshetau and Krasny Yar (Akmola region) were analyzed. Microplastics were detected in all samples, with concentrations ranging from 2.0 × 10−2 to 6.0 × 10−2 particles/dm3, predominantly in fiber form (74.1%). Outdated technologies and non-compliance with treatment regimens contribute to poor water quality, including high turbidity (87% of samples), color deviations (40% of samples), and acidity issues (20% of samples). To address these challenges, the study examined the sorption efficiency of different sorbents, with results indicating high retention rates (82.7–97.8%) for microplastic particles. Notably, aliphatic structures like PE and PP exhibited higher retention than PET. Among the sorbents tested, the synthesized carbon sorption material (CSM) demonstrated the highest efficiency in both microplastic retention and improvement in water quality parameters, making it a promising option for water treatment facilities and household filters.
