Fast and simple assessment of surface contamination in operations involving nanomaterials 2019 Access copy available to the general public Unrestricted The deposition of airborne nanosized matter onto surfaces could pose a potential risk in occupational and environmental scenarios. The incorporation of fluorescent labels, namely fluorescein isotiocyanate (FITC) or tris-1, 3-phenanthroline ruthenium (II) chloride (Ru(phen)3Cl2), into spherical 80-nm silica nanoparticles allowed the detection after the illumination with LED light of suitable wavelength (365 or 405 nm respectively). Monodisperse nanoparticle aerosols from fluorescently labeled nanoparticles were produced under safe conditions using powder generators and the deposition was tested into different surfaces and filtering media. The contamination of gloves and work surfaces that was demonstrated by sampling and SEM analysis becomes immediately clear under laser or LED illumination. Furthermore, nanoparticle aerosols of about 105 nanoparticles/cm3 were alternatively fed through a glass pipe and personal protective masks to identify the presence of trapped nanoparticles under 405 nm or 365 nm LED light. This testing procedure allowed a fast and reliable estimation of the contamination of surfaces with nanosized matter, with a limit of detection based on the fluorescence emission of the accumulated solid nanoparticles of 40 ng of Ru(phen)3@SiO2 of silica per mg of non-fluorescent matter. info:eu-repo/grantAgreement/ES/DGA/FSE info:eu-repo/grantAgreement/EC/FP7/263147/EU/Development of reference methods for hazard identification, risk assessment and LCA of engineered nanomaterials/NANOVALID info:eu-repo/grantAgreement/ES/MINECO/JCI-2012-13421 info:eu-repo/grantAgreement/ES/MINECO/RYC-2011-07641 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 9.038 2019 2.01 2019 ENVIRONMENTAL SCIENCES 8 / 265 = 0.03 2019 Q1 T1 Environmental Chemistry 2019 Q1 ENGINEERING, ENVIRONMENTAL 4 / 53 = 0.075 2019 Q1 T1 Environmental Engineering 2019 Q1 Waste Management and Disposal 2019 Q1 Pollution 2019 Q1 Health, Toxicology and Mutagenesis 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Jiménez, R.
