Dataset for: PVC microplastic release from drinking water pipes under repeated hydraulic transients (water hammer)
Year: 2026
Type: dataset
Abstract: This dataset supports the article “Water hammer as a driver of microplastic release from PVC drinking water pipes” (Criollo et al., submitted to Environmental Science: Water Research & Technology). It contains the data underlying the quantification of polyvinyl chloride (PVC) microplastics released from PVC drinking water pipes subjected to repeated hydraulic transients (water hammer) under three initial deformation states (no, low and high deformation), in nine valid experimental runs. Particles were analysed by focal plane array micro-Fourier transform infrared spectroscopy (µFTIR) on two zinc selenide windows per sample and identified with siMPle software. Particles assigned to the groups “PVC” and “vinyl chloride copolymer” were counted as PVC. The dataset includes:(1) a list of all identified PVC particles per run and window, with polymer group, reference spectrum, AAU match score, major and minor dimensions, area and estimated mass;(2) particle counts per window and run, extrapolated to the full sample volume and normalised to the internal pipe surface area;(3) the spreadsheet with calculations for the exposure scenarios (release rates, concentrations and per-person intake). Particle mass was estimated following Simon et al. (2018), as computed by siMPle.
