Quantification of Nanoplastics and Inorganic Nanoparticles via Laser-Induced Breakdown Detection (LIBD).

ABSTRACT: Nanoparticles with diverse characteristics are difficult to quantify at low concentrations in the water environment (10⁶-10⁹ particles mL^-1 for nanoplastics originating from the breakdown of plastic debris) for the evaluation of effective treatment methods. This study examines the sensitivity, or limit of detection (LOD), of laser-induced breakdown detection (LIBD) for the counting of nanoparticles, including nanoplastics. For polystyrene (PS) standards with sizes of 20-400 nm, LIBD shows relatively low LODs (for example, 2 × 10⁶ particles mL^-1 for 100 nm particles) compared with turbidity monitoring, UV-vis spectroscopy (both 6 × 10⁸ particles mL^-1), and nanoparticle tracking analysis (2 × 10⁷ particle
