This study evaluated the emissions characteristics of hazardous material during fused deposition modeling type 3D printing. Particulate and gaseous materials were measured before, during, after printing in an exposure chamber. One ABS two PLA (PLA1 PLA2) cartridges tested three times. For online monitoring, a scanning mobility particle sizer, light scattering instrument, total volatile organic compound (TVOC) monitor employed polycarbonate filter various adsorbent tubes used for offline...
Particulate respirators have been used in both general environments and the workplace. Despite existence of certified for workers, no strict regulations exist masks worldwide. The aims this study were to evaluate filter efficiency various mask types using Korean Food Drug Administration (KFDA) [similar European Union (EU) protocol] National Institute Occupational Safety Health (NIOSH) protocol compare test results. We tested a total 44 brands four (anti-yellow sand, medical, quarantine,...
Traffic has long been recognized as the major contributor to polycyclic aromatic hydrocarbon (PAH) concentrations. However, this does not consider contribution of cooking sources PAHs. This study set out, first, assess characteristics PAHs and their corresponding benzo[a]pyrene equivalent (B[a]Peq) emissions from urban atmosphere. To illustrate importance sources, PAH traffic were then calculated compared. The entire was conducted on a city located in southern Taiwan. samples collected...
Occupational Stress in Nurses Psychiatric Institutions Taiwan: Hsiu‐Chuan Shen, et al. Department of Environmental and Health, College Medicine, National Cheng Kung University, Taiwan —Nurses are known to be exposed occupational stress. However, stress is not well documented for nurses psychiatric institutions Taiwan. A cross‐sectional study was conducted explore the work‐related risk factors structured questionnaire distributed at five state‐owned hospitals 2001. Demographic information,...
This study set out to identify possible PCDD/F emission sources for different atmospheric environments in a highly industrialized city located southern Taiwan. We collected stack flue gas samples from five main stationary of the municipal solid waste incinerators (MSWIs), medical (MWIs), electric arc furnaces (EAFs), secondary aluminum smelters (ALSs), and sinter plants assess characteristics their emissions. For mobile sources, congener profiles reported U.S. EPA's database unleaded...
This study was set out to characterize PCDD/F emissions from crematories and assess their impacts on the surrounding environment. Two located in southern Taiwan were investigated, including one (C1) with no air pollution control device installed other (C2) a bag filter. Results show mean (11% oxygen) stacks of Cl C2 2.36 0.322 ng I-TEQ Nm(-3), respectively. The emission factors for C1 13.6 6.11 microg body(-1), removal efficiency filter PCDD/Fs 55.1%. estimated rate all 0.838 g I-TEG yr(-1)...
The developments of both biodiesel and emulsified diesel are being driven by the need for reducing emissions from engines saving energy. Artificial chemical additives also used in increasing their combustion efficiencies. But effects associated with use additive/biodiesel/diesel blends have never been assessed. In this research, premium fuel (PDF) was as reference fuel. A soy-biodiesel selected test biodiesel. biosolution made 96.5 wt % natural organic enzyme-7F (NOE-7F) 3.5 water (NOE-7F...
Abstract. We present the first systematic analysis for new particle formation (NPF), growth and shrinkage of particles at four different sites in subtropical central Taiwan. A total 14 NPF events were identified from 137 days ambient measurements during a cold warm season. The measured rates 10 nm (J10) range 4.4–30 cm−3 s−1 7.4–24 h−1, respectively. onset coincided with decreases condensation sink (CS) increases SO2 under enhanced atmospheric mixing dilution. However, lower or comparable on...
ABSTRACT The diarrheal pathogen Clostridium difficile consists of at least six distinct evolutionary lineages. RT017 lineage is anomalous, as strains only express toxin B, compared to from other lineages that produce toxins A and B and, occasionally, binary toxin. Historically, initially was reported in Asia but now has been worldwide. We used whole-genome sequencing phylogenetic analysis investigate the patterns global spread population structure 277 isolates animal human origins...
Purpose Long-term follow-up studies of asbestos-related cancer in shipbreaking workers are lacking. This study examines the relationship between incidence and asbestos exposure among former Taiwan workers. Methods A total 4,427 22,135 population-based matched controls were successfully followed this study. The cohort was linked to Cancer Registry for new cases. adjusted hazard ratio (aHR) calculated with Total Exposure Potential Scores (TEP) asbestos. Results Follow-up generated 109,932...
The sheared-flow-stabilized Z pinch concept has been studied extensively and is able to produce fusion-relevant plasma parameters along with neutron production over several microseconds. We present here elevated electron temperature results spatially temporally coincident the source. An optical Thomson scattering apparatus designed for FuZE device measures temperatures in range of 1–3 keV on axis device, 20 cm downstream nose cone. 17-fiber system radial profiles temperature. Scanning laser...
Our objective in this study was to assess the effect of using two kinds lead-free gasoline [including 92-lead-free (92-LFG) and 95-lead-free (95-LFG), rated according their octane levels] replace use premium leaded (PLG) on emissions polycyclic aromatic hydrocarbons (PAHs) corresponding benzo[a]pyrene equivalent (BaP(eq)) amounts from gasoline-powered engine. The results show that three fuels originally contained similar total PAHs BaP(eq) contents; however, we found significant differences...
This study investigates the emissions of polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) from four electric arc furnaces (EAFs) eight secondary aluminum smelters (secondary ALSs) in Taiwan. The mean PCDD/F International-Toxicity Equivalents (I-TEQ) concentrations stack gases these EAFs ALSs are 0.28 ng I-TEQ/Nm3 (relative standard deviation [RSD]= 100%) 3.3 (RSD = 260%), respectively. high RSDs, especially for those obtained ALSs, could be caused by intrinsic differences...
