Today, engineered nanomaterials are frequently used. Nanosized titanium dioxide (TiO2) has been extensively used for many years and graphene is one type of emerging nanomaterial. Occupational airborne exposures to important ensure safe workplaces extend the information needed complete risk assessments. The main aim this study was characterize workplace emissions exposure nanoplatelets, oxide, TiO2 nanofibers (NFs) nanoparticles (NPs) during down-stream industrial handling. Surface...
Globally, 3 billion people rely on solid biomass fuel for their everyday cooking, most often using inefficient cooking practices, leading to high exposure levels of household air pollution. This is subsequently associated with negative health and climate impact. Further, the use fuels applies pressure natural forests, resulting in deforestation, loss biodiversity, soil degradation. Improved cookstove technologies are being promoted mitigate these issues. However, limited knowledge exists...
Engineered nanomaterials (ENMs) are increasingly produced and used today, but health risks due to their occupational airborne exposure incompletely understood. Traditionally, nanoparticle (NP) toxicity is tested by introducing NPs cells through suspension in the growth media, this does not mimic respiratory exposures. Different methods introduce aerosolized cultured at air-liquid-interface (ALI) have been developed, require specialized equipment associated with higher cost time. Therefore,...
Abstract Background Diesel engine exhaust causes adverse health effects. Meanwhile, the impact of renewable diesel exhaust, such as hydrotreated vegetable oil (HVO), on human is less known. Nineteen healthy volunteers were exposed to HVO for 3 h in a chamber with double-blind, randomized setup. Exposure scenarios comprised from two modern non-road vehicles 1) no aftertreatment system (‘HVO PM+NOx ’ PM1: 93 µg m −3 , EC: 54 NO: 3.4 ppm, NO 2 : 0.6 ppm), 2) an containing oxidation catalyst and...
Cleaning workers are exposed to many risk factors, including handling of cleaning products. Epidemiological studies show that they have a high incidence asthma and other respiratory symptoms. Some indicated an even higher in individuals using sprays regularly. It is known produce aerosol can expose the system chemicals. Knowledge physical characteristics airborne particles, as well gas phase, needed determine how affect tract why cause airway The aim this study was characterize aerosols from...
In the strive towards a circular economy, metal waste recycling is growing industry. During process, particulate matter containing toxic and allergenic metals will be emitted to air causing unintentional exposure humans environment.In this study detailed characterization of particle emissions workplace exposures were performed, covering full size range from 10 nm µm, during three different material flows: Waste electrical electronic equipment (WEEE), scrap, cables.Both direct-reading...
Abstract Background Cleaning workers are exposed to chemicals and high physical workload, commonly resulting in airway problems pain. In this study the response upper airways workload following airborne ergonomic exposure of cleaning spray was investigated. Methods A survey answered by professional investigate their use sprays perceived effects on eyes, musculoskeletal human chamber then conducted with 11 8 non-professional exposure, acute eyes airways, load during sprays, foam application...
Abstract Objectives The use of manufactured nanomaterials is increasing globally. Although multi-walled carbon nanotubes (CNTs) are used in a wide range applications, only limited data available on emissions and exposures during CNT composite production. No exposure using portable aethalometers the personal breathing zone (PBZ) to monitor occupational CNTs have yet been published. aim this study was characterize production, sawing, shear testing. We also investigated whether real-time...
Nanowires are a high-aspect-ratio material of increasing interest for wide range applications. A new and promising method to produce nanowires is by aerotaxy, where the wires grown in continuous stream gas. The aerotaxy can grow much faster than more conventional methods. have important properties common with asbestos fibers, which indicate that there be potential health effects if exposure occurs. No conclusive (or emission) data from aerotaxy-production has so far been published.Different...
Firefighters can be occupationally exposed to a wide range of airborne pollutants during fire-extinguishing operations. The overall study aim was characterize occupational exposure smoke for several groups workers responding fires, with specific aims determine the correlations between markers and biologically assess their systemic polycyclic aromatic hydrocarbons (PAHs) in urine. Personal measurements equivalent black carbon (eBC), elemental (EC), organic (OC), nitrogen dioxide (NO
Abstract Background: Diesel engine exhaust causes adverse health effects. Meanwhile, the impact of renewable diesel on human is less known. In this study, nasal patency, pulmonary function, and self-rated symptoms were assessed in 19 healthy volunteers after two separate 3-hour exposures to (hydrotreated vegetable oil [HVO]) exhaust, exposure filtered air (FA) for comparison. The HVO generated with modern non-road vehicles (2019) having either: 1) no aftertreatment system (HVO PM+NOx ), or...
Abstract Waste of electrical and electronic equipment (WEEE) is one the fastest-growing waste streams in EU. The airborne occupational environmental exposures generated by this handling are poorly quantified, growing use nanomaterials electronics adds to uncertainty risk assessment. Emission personal exposure measurements were carried out during industrial recycling for three different metal flows: WEEE, scrap cables. Size distributions number-, mass- lung deposited surface area...
The dominant road traffic particle sources are wear particles from the and tire interface, vehicle brake pads. aim of this work was to investigate effect on pulmonary function biomarkers in isolated perfused rat lungs. Particles were sampled studded three pavements containing different rock materials a simulator; two pad using pin-on-disk machine. Isolated lungs inhaled coarse fine fractions resulting an estimated total lung dose 50 μg. tidal volume (TV) measured during exposure following...
Approximately 16 % of adult onset asthma is caused by occupational exposure. The need for early detection irritant key in treating and preventing the progression disease. aim work was to investigate if exposure irritants cause change gas composition exhaled breath, "exhalome". We studied 15 female hairdressers exposed a controlled dose aerosolized bleach powder sealed climate chamber. subjects' self-reported symptoms, spirometry components were monitored. exhalome collected breath holding...
