Summary 3D printers are currently widely available and very popular among the general public. However, use of these devices may pose health risks to users, attributable air‐quality issues arising from gaseous particulate emissions in particular. We characterized a low‐end printer based on material extrusion, using most common polymers: acrylonitrile‐butadiene‐styrene (ABS) polylactic acid (PLA). Measurements were carried out an emission chamber conventional room. Particle rates obtained by...
Increasing temperatures and more frequent heatwave events pose threats to population health, particularly in urban environments due the heat island (UHI) effect. Greening, particular planting trees, is widely discussed as a means of reducing exposure associated mortality cities. This study aims use data from personal weather stations (PWS) across Greater London Authority understand how vary according tree canopy coverage estimate heat-health impacts London's trees.

Human-induced resuspension of floor dust is a dynamic process that can serve as major indoor source biological particulate matter (bioPM). Inhalation exposure to the microbial and allergenic content associated with adverse protective health effects. This study evaluates infant adult inhalation exposures respiratory tract deposited dose rates resuspended bioPM from carpets. Chamber experiments were conducted robotic crawling an performing walking sequence. Breathing zone (BZ) size...
Material extrusion (ME) desktop 3D printing is known to strongly emit nanoparticles (NP), and the need for risk management has been recognized widely. Four different engineering control measures were studied in real-life office conditions by means of online NP measurements indoor aerosol modeling. The general ventilation, local exhaust ventilation (LEV), retrofitted enclosure, enclosure with LEV. Efficiency between was compared based on particle number surface area (SA) concentrations from...
This study considers fundamental methods in occupational risk assessment of exposure to airborne engineered nanomaterials. We discuss characterization particle emissions, assessment, hazard with vitro studies, and range using calculated inhaled doses dose-response translated humans from studies. Here, the were utilized assess workers' inhalation nanodiamonds (NDs) during handling sieving ND powder. NDs agglomerated over 500 nm particles, mean levels different work tasks varied 0.24 4.96...
While production and use of carbon nanotubes (CNTs) is increasing, workers exposure to CNTs expected increase as well, with inhalation being potentially the main pathway for uptake. However, there have been few studies reporting results about workers' personal CNTs. In this study, worker single-walled (SWCNTs) during conductive films in a modern up-scaling factory was assessed. Particulate matter concentrations (2.5–10 μm) CO CO2 were monitored by using real-time instruments. Workers' levels...
Due to the health risk related occupational air pollution exposure, we assessed concentrations and identified sources of particles volatile organic compounds (VOCs) in a handcraft workshop producing fishing lures. The work processes site included polyurethane molding, spray painting, lacquering, gluing. We measured total VOC (TVOC) particle size distributions at three locations representing various phases manufacturing assembly process. mean working-hour TVOC studied were 41, 37, 24 ppm...
Pulmonary exposure to micro- and nanoscaled particles has been widely linked adverse health effects high concentrations of respirable are expected occur within around many industrial settings. In this study, a field-measurement campaign was performed at an manufacturer, during the production paints. Spatial personal measurements were conducted results used estimate mass flows in facility airborne particle release outdoor environment. Airborne number concentration (1 × 103–1.0 104 cm−3),...
Abstract Particle and gaseous contaminants from industrial scale additive manufacturing (AM) machines were studied in three different work environments. Workplaces utilized powder bed fusion, material extrusion, binder jetting techniques with metal polymer powders, filaments, gypsum powder, respectively. The AM processes operator’s point of view to identify exposure events possible safety risks. Total number particle concentrations measured the range 10 nm 300 breathing zone using portable...

Ionized acetates were used as model compounds to describe gas-phase behavior of oxygen containing with respect their formation dimers in ion mobility spectrometry (IMS). The ions created using corona discharge at atmospheric pressure and separated a drift tube before analysis the by mass spectrometry. At ambient operational temperature our instrument, all studied formed dimers. Using homolog series n-alkyl-acetates, we found that collision cross section dimer was smaller than monomer same...
Design for additive manufacturing is adopted to help solve problems inherent attaching active personal sampler systems workers monitoring their breathing zone. A novel and parametric 3D printable clip system was designed with an open source Computer-aided design (CAD) additively manufactured. The concept first tested a simple design, when it found be functional, the ability of innovative extended other applications demonstrated by designing another tooling system. mechanical stress test...
This study describes workers' exposure to fine and ultrafine particles in the production chain of ferrochromium stainless steel during sintering, smelting, melting, hot cold rolling operations. Workers' personal inhalable dust was assessed using IOM sampler with a cellulose acetate filter (AAWP, diameter 25 mm; Millipore, Bedford, MA). Filter sampling methods were used measure particle mass concentrations fixed locations. Particle number size distributions examined an SMPS+C sequential...
An ion mobility spectrometer (IMS) was used to study gas phase compounds during nucleation and growth of secondary organic aerosols (SOA). In this SOA particles were generated by oxidizing α-pinene with O3 OH in a 6 m3 reaction chamber.

Abstract. Ion mobility spectrometer (IMS) was implemented to measure gas phase compounds from ambient air in order study the suitability of technique for on-line atmospheric measurements. The measurements took place at SMEAR II station Hyytiälä, Finland during spring periods on 2008 and 2009. We were able separate several different atmosphere related ion peaks form measured distributions. hypothetic origins these are discussed accompanying comparison with earlier trace by techniques....
