Intense generation of respirable metal nanoparticles from a low-power soldering unit
Link to Journal Abstract
Evidence of intense nanoparticle generation from a low power (45 W) flux soldering unit is presented. This is a familiar device often used in daily life, including home repairs and school electronic laboratories. We demonstrate that metal-containing nanoparticles may reach high concentrations (ca. 106 particles/cm3) within the breathing range of the operator, with initial size distributions centered at 35–60 nm The morphological and chemical analysis of nanoparticle agglomerates collected on TEM grids and filters confirms their multiparticle structure and the presence of metals.
This study investigates nanoparticle generation from a low power (45 W) flux soldering unit, determining concentrations of metal-containing nanoparticles produced, their size distribution and the morphological and chemical analysis of nanoparticle agglomerates collected on TEM grids and filters.
