In the present work, we investigate effect of weathering duration on a commercial photocatalytic nanocoating basis its nanoparticle emission tendency into two media, air and water. It is found that increased results in stepwise structural deterioration nanocoating, which turn decreases life, changes removal mechanism, increases particle concentration. Emission free TiO2 nanoparticles to be dependent. Three quantities are introduced: transition pace (ETP), stable level (SEL), (SED). By linear...
Recently, much progress has been made to develop more physiologic in vitro models of the respiratory system and improve simulation particle exposure through inhalation. Nevertheless, field nanotoxicology still suffers from a lack relevant methods predict accurately effects observed vivo, especially after exposure. In this context, aim our study was evaluate if exposing pulmonary cells at air-liquid interface aerosols inhalable poorly soluble nanomaterials generates different toxicity...
Transmission electron microscopy (TEM) coupled with energy-dispersive X-ray (EDX) offers a very comprehensive tool for individual particle analysis allowing the determination of size, morphology, specific surface, and elemental composition. This information is needed in aerosol studies, especially field nanomaterials. However, observations TEM require controlled sampling on an adapted support, namely grid. Techniques grids are great interest to analysis. Indeed, sample preparation not...
The potential health effects of fine and ultrafine particles are increasing concern. A better understanding particle characteristics dispersion behavior is needed. This study aims at characterizing spatial temporal variations in after emission from a model source an experimental house. Particles emitted by incense stick burning for 15 min were characterized. Number concentration, specific surface area mass measured. Partial chemical analysis was also realized. Near the stick, maximum...
In the context of air quality improvement, there is an increasing need to monitor gas and particle emissions originating from exhaust stacks (incinerators, foundries, etc.) for regulation enforcement purposes. Lots pollutants are targeted; among them, heavy metals mostly found in particulate forms. Hence, a promote development suitable on line analytical techniques. To that end, laser-induced breakdown spectroscopy (LIBS) appears be good technique. Indeed, it quantitative, fast (<1 min),...
Nanoclay-based nanocomposites have been widely studied and produced since the late 1990s, frequently end up in waste disposal plants. This work investigates behavior of PA6/HNTs (nylon-6 incorporating halloysite nanotubes) during incineration. Incineration tests were performed at lab-scale using a specific tubular furnace modified order to control key incineration parameters within both combustion postcombustion zones. The residues aerosol (particulate matter gas phase) collected downstream...
Manufactured products are being coated with nanoparticles in order to functionalize them antibacterial or self-cleaning properties improve their durability etc. As the (eco-) toxicological effects of not well known yet, use could lead new potential risks for workers, consumers and environment. This study focuses on release during operations related handling processing an automotive part. The part is made up a metallic alloy and, reduce friction, nano-coated inorganic fullerenes. mechanical...
A parametric study on the release of titanium dioxide (TiO 2 ) nanoparticles from two commercial photocatalytic nanocoatings is carried out. For this, abrasion tests are performed them. The formed aerosols characterized by their number concentration, particle size distribution, individual shape, size, and chemical composition. appear to exhibit contrastingly opposite behavior with respect concentration released particles. Having irregular shapes, particles found have unimodal distributions...
The NANOFOL concept aims at creating nanodevices containing a drug for inflammatory disorder treatment. This paper provides recommendations nanosafety based on measurement campaign which aimed identifying exposure risks with respect to two specific phases of the product’s lifecycle, that is, production device and its waste management. nanoparticle’s presence both in air liquid phase was studied. While no emissions were detected during period, many have been made, particularly regarding...
The growing use of nanomaterials requires the development tools enabling study risks to consumer, worker, and environment. This relates risk suspension inhalable particles upon production and/or powders constituted nanoobjects, more specifically potential vortex shaker as apparatus for determining dustiness a powder atmosphere generating tool experimental toxicology. chosen this was Graphistrength C100 (ARKEMA), multiwalled carbon nanotube. Its agitation in at 1500 rpm leads an aerosol...
