“…Raw and treated drinking water can be sampled for MPs in different ways. The simple one is to take a conventional grab sample in glass [26,43,59,60,63,64,67] , aluminum [44] , stainless steel [56] , or even high-density polyethylene (HDPE) [58,66] bottles and process them in a laboratory. This is appropriate for volumes between 1 and 25 L. If a higher water volume is needed (> 50 L), grab samples could be immediately passed through a stainless steel wire mesh of different sizes, and then reduced volume samples are taken to the laboratory [45] .…”

“…The most important problem with drinking water is the presence of mineral salts. However, many works do not emphasize this issue [43,44,[46][47][48]55] . Some studies used HCl, HNO 3 , or H 2 SO 4 to remove CaCO 3 and iron or EDTA to sequester mineral salts in general.…”

“…Polymer chemical identification (and sometimes its quantification) is performed by using µFTIR [44,48,50,52,56,60,63,69] , µ-Raman [30,43,45,46,50,53,57,59,64,[66][67][68]70] , or Py-GC-MS [6,26,52,54,55] . However, several studies used ATR-FTIR spectroscopy [54,61,69,71] and Raman spectroscopy [63] .…”

“…Seven studies focused on the occurrence of MPs and/or NPs in bottled water. Interestingly, Almaiman et al [44] reported that about 57% of the samples had quantifiable levels of MPs in the size range of 25-500 μm. Ibeto et al [51] found MPs (20-100 µm) in 92% of the samples.…”

“…Zucarello et al [72] decreased the particle size detected to a range of 0.5-10 µm and showed concentrations between 3.16 × 10 7 and 1.1 × 10 8 MPs/L, showing the importance of detecting smaller MPs to make studies more comparable. Several types of MPs were detected, but PET (the most common plastic in bottles) and PE (most common plastic in caps) were the main plastic types [44,51,53,57,62,65,70,72] . One of the studies analyzed the effect of water treatment and bottling by determining the concentration of MPs after each step [70] including raw and deferrized water, empty bottles, and caustic cleaning solutions.…”

Aim: The commonly used analytical methods for microplastic (MPs) detection in drinking water and the threat of MP pollution in water intended for human consumption to human beings are presented through a systematic review. Furthermore, MP occurrence, transport, and fate from raw to treated drinking water, tap water, and bottled water, as well as the possible health impacts of MPs on human beings, are also evaluated. Methods: Systematic review included articles published in scientific journals that contain specific keywords in the title and were searched in Web of Science (WOS) and Scopus. The literature was selected and extracted by two reviewers based on the PRISMA-A guidelines, which recommend including 57 items. Results: The experimental studies pointed out that sampling is performed using grab or reduced samples, and sample treatment involves mostly oxidation with hydrogen peroxide and density separation. The minimum sample size obtainable in the extraction and the maximum density of the polymer separable from the matrix provided different results. Clearly, the determination of MPs involves the simultaneous application of several analytical techniques, including optical, fluorescence, and electronic microscopies, µFTIR, µ-Raman, and pyrolysis gas chromatography-mass spectrometry. The determination technique also provides different results according to the sensitivity as well as the minimum size determinable. These studies are mostly devoted to establishing the occurrence, transport, and fate within the supply network, the efficiency in removal of MPs from drinking water by treatment plants, and the risk to humans. The MP concentration in drinking water reservoirs is highly variable. However, tap water always presents lower concentrations of MPs than the water that enters the drinking water treatment plants because the different treatments are efficient at removing MPs. Although it has not been fully demonstrated that MPs are toxic to humans, the effects point to oxidative stress, gastrointestinal irritation, microbiome irregularities, and changes in lipid metabolism. Conclusion: Analytical methods present some common features as a first step towards harmonization. However, it is still unknown whether the analytical methods could influence the disparity of the results. The MP concentration in drinking water is low in comparison to other types of water. MPs are not exempt from hazards to human health.

Microplastics (MPs) are emerging pollutants that are ubiquitous in the environment, and may be a potential threat to human health. This review describes the MP exposure sources and pathways through drinking water, food intake, and air inhalation. The unregulated discharge of MPs in water sources and the absence of required MP filter technology in water treatment plants are important routes of MP exposure through drinking water. The presence of MPs in food may lead to the accumulation of MPs in the body. Exposure to MPs can occur through airborne fallout and dust inhalation in both indoor and outdoor environments. This review summarizes the MP exposure sources and possible pathways in the human body, and illustrates that the intake of drinking water, food consumption, and air inhalation should be assessed in during routine activities.
