“…The concentration ranged from LOQ to 0.05 MPs per litre with a mean concentration calculated of <LOQ (0.01 MPs per litre). These concentrations are in line with our previous study where 0.06 ± 0.04 MPs per litre were detected at the outlet of the DWTP (Dalmau-Soler et al, 2021) which supplies drinking water to the sampled cabinets. The size of detected MPs ranged from 83 to 3228 μm, and 58% were fibres versus a 42% of fragments, similar to the outlet of the DWTP (55% of fibres and 45% of fragments) (Figure 2).…”

“…This abundance pattern was broadly in accordance with the samples of the outlet of the DWTP. Figure 3 compares the polymer type pattern obtained in this study (eliminating PTFE contamination) with the data reported previously in the treated water sampled in the outlet from DWTP where the concentration, the type and the shape of MPs are similar (Dalmau-Soler et al, 2021). PE was not detected in any of the samples analysed and indicates that a priori, there is no contribution of the PE pipes (regardless of the % of PE constituting the pipes of each sector along the water supply network) and the linear distance from the DWTP (Table 1).…”

“…However, with the advent of MP pollution and risk of being present in drinking water, especially when the intake is a river that flows through a very anthropogenized area, it was deemed necessary to include MP analysis as part of the contaminant monitoring scheme of the DWTP. In a previous study, we have shown that 95% of MPs were removed in Sant Joan Despí DWTP (Dalmau-Soler et al, 2021). The concentrations at the outlet of the DWTP were of 0.06 ± 0.04 MPs per litre, but no information is available on MPs in tap water once pumped into the drinking water distribution network.…”

The aim of the present study was to evaluate the presence of microplastics in drinking water along a large distribution water supply network. Tap water was collected in situ at sampling cabinets using an in‐line sampling procedure that provided a representative sample with minimal risk of external contamination and avoided the transportation of large volumes to the laboratory. Microplastics > 50 μm were analysed via Fourier transform infrared spectroscopy (FTIR). Microplastics were detected in 38% of samples with a mean concentration of 0.01 microplastics per litre and polymers identified were polypropylene (PP), polyester (PES) and polyamide (PA). Detection of polytetrafluoroethylene (PTFE) and silicone particles were associated to the maintenance of cabinets. This study contributes to increase the knowledge regarding the presence and behaviour of microplastics throughout a large drinking water supply network providing water to 3 000 000 inhabitants. Results indicate that the pipes and the supply network not release microplastics into the drinking water.

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.
