Estimating the true detection limit for particle number concentration based on the procedural blank sample reported by Qian et al. (1). Note that the measured concentration of micro/nanoplastics in every bottled water sample is below that of the procedural blank and far below the theoretical detection limit of +3 SD (or “3-sigma”) (2).
