“…It has been reported that the resin and curing agents could cause occupational contact dermatitis, occupational asthma (Pietranek, 2007;Suojalehto et al, 2019), and serious lung diseases (Pesonen et al, 2016). On the other hand, additives in coating powders, which are nanometers in size, include carbon nanotubes, metal oxides (e.g., Cr 2 O 3 , Fe 2 O 3 , and ZnO), and toxic metals (Ni, Fe, Al, and Pt) (West et al, 2021). Metals and metal oxides in additives can cause serious diseases such as lung carcinogens, metal fume fever, and siderosis (Antonini et al, 2021).…”

Background: Powder-coating processes have been extensively used in various industries. The submicron particles generated during the powder-coating process in the workplace have complex compositions and can cause serious diseases. The purpose of this study was to better understand the health risks and respiratory intake of submicron particles during the powder coating process.Methods: The concentrations of and variations in submicron particles were measured using real-time instruments. The health risks of submicron particles were analyzed using the Stoffenmanager Nano model. A new computational fluid dynamics model was used to assess the respiratory intake of ultrafine particles (UFPs), which was indicated by the deposited dosage of UFPs in the olfactory area, nasal cavity, and lungs. The deposited doses of UFPs were used to calculate the average daily doses (ADDs) of workers, according to the method described by the Environmental Protection Agency.Results: The number concentration (NC), mass concentration, surface area concentration, personal NC, and lung-deposited surface area concentration of submicron particles were >105 pt/cm3, 0.2–0.4 mg/m3, 600–1,200 μm2/cm3, 0.7–1.4 pt/cm3, and 100–700 μm2/cm3, respectively. The size distribution showed that the submicron particles mainly gathered between 30 and 200 nm. The health risk of submicron particles was high. Upon respiratory intake, most UFPs (111.5 mg) were inhaled into the lungs, a few UFPs (0.272 mg) were trapped in the nasal cavity, and a small minority of UFPs (0.292 mg) were deposited in the olfactory area. The ADD of male workers with 10 years of exposure in the olfactory area, nasal cavity, and lung were 1.192 × 10–3 mg/kg·d−1, 1.11 × 10–3 mg/kg·d−1, and 0.455 mg/kg·d−1, respectively.Conclusion: Owing to the high concentrations of submicron particles, the workers involved in the powder-coating process are at a high health risk. Moreover, the respiratory intake of UFPs by workers is high, which is suggested by the highly deposited dosage of UFPs in the lungs and the corresponding high ADD in workers. Control measures, including engineering control, management control, and personal protective equipment, must be improved for the protection of workers.

Particulate matter (PM) is a known indoor air pollutant, and it can cause adverse effects, including decreased lung function, increased respiratory symptoms such as bronchitis and asthma, and increased morbidity and mortality due to cardiovascular diseases. [1][2][3][4] The presence of airborne particles indoors is caused by outdoor PM and indoor activities such as cooking, cleaning, use of sprays, as well as candles and incense. [5][6][7][8] In addition, a large fraction of indoor particles eventually settles on surfaces which then can then be resuspended back into the air by human activities. [9][10][11][12][13] The resuspension of particles is an important indoor particle source. Resuspension of different types of particles (e.g., silica particles, 14 potassium chloride [KCl] salt particles, 15 alumina powder, 16 cigarette smoke particles, 17 Arizona Test Dust, 18,19 biological particles, 10,20 and dust from real homes 5,21 ) has been investigated.

BackgroundEngineered nanomaterials (ENMs) may pose health risks to workers. Objectives were to characterize ENM applications in construction, identify exposure scenarios, and evaluate the quality of safety data sheets (SDSs) for nano‐enabled construction products.MethodsSDSs and product data were obtained from a public database of nano‐enabled construction products. Descriptive statistics were calculated for affected trades, product categories, and types of ENMs. A sample of SDSs (n = 33) was evaluated using modified criteria developed by NIOSH researchers. Bulk analysis via transmission electron microscopy characterized nanoparticles in a subset of products.ResultsCompanies report using >50 ENMs in construction products. ENM composition could not be determined via SDSs for 38.1% of the 907 products examined. Polymers and metal oxides tied for most frequently reported ENMs (n = 87, 9.6%). Nano silica, graphene, carbon nanotubes, and silver nanoparticles were also frequently reported. Most of the products were paints and coatings (n = 483, 53.3%), followed by pre‐market additives, cementitious materials, insulation, and lubricants. Workers in twenty construction trades are likely to handle nano‐enabled products, these particularly encompass cement and brick masons, painters, laborers, carpenters, glaziers, and insulators. A wide range of exposure scenarios were identified. SDSs were classified as satisfactory (18%), in need of improvement (12%), or in need of significant improvement (70%). Bulk analyses revealed discrepancies between actual ENM composition and those in SDSs.Discussion and ConclusionThere has been significant progress investigating risks to construction workers posed by ENMs, but SDSs need major improvements. This study provides new insights on the use of ENMs in construction, exposure risks, and hazard communication.
