Silica nanomaterials (NMs) are widely used in semiconductor, agriculture, cosmetics, and biomedical applications, addition to other industries. We investigated the toxic effect of silica NMs on rheological characteristics human red blood cells (RBCs), including hemolysis, deformability, aggre gation, morphological changes. Red were exposed nanoparticles (d =∼200 nm) or nanowires nm, l = 1μm 10μm) at a range concentrations incubation times. Rheological measured using microfluidic-laser...
A national survey on workplace environment nanomaterial handling and manufacturing was conducted in 2014. Workplaces relevant to nanomaterials were the order of TiO 2 (91), SiO (88), carbon black (84), Ag (35), Al O 3 ZnO (34), Pb (33), CeO (31). The results indicated that number workplaces or 340 (0.27% total 126,846) workplaces. used products 546 (1.60 per company) 583 (1.71 company), respectively. For most workplaces, exposure hazardous particulate materials, including nanomaterials,...
A clonorchiasis case in a captive leopard cat, Prionailurus bengalensis euptilurus, was confirmed by ultrasonographic findings and egg morphologies found the bile juice sample Korea. The cat introduced from wild habitat of Gyeongsangnam-do, to Cheongju Zoo Cheongju-si, Chungcheongbuk-do, Korea August 2014. Physical examinations were basically performed for quarantine check-up health. comparatively good health except anorexia. cyst-like duct dilation increased echogenicity gall bladder wall...
Objectives: The purposes of this study are to investigate workers' exposures respirable particles generated in taconite mines and compare two metric methods for mass concentrations using direct-reading instruments. Methods: Air monitorings were conducted at six where subjects have been exposed primarily particulate matters crushing, concentrating, pelletizing processes. samples collected during 4 hours the entire work shift similarly exposure groups(SEGs) nine jobs(N=37). Following...
This study examines particulate matter (PM) concentrations, specifically PM<sub>10</sub>, PM<sub>2.5</sub>, and PM<sub>1.0</sub>, at an urban site in Ansan, South Korea. Three BAM-1020 continuous monitors measured PM<sub>1.0</sub> hourly from January to December 2021, with data acquisition rates of 97.1%, 97.3%, 93.4%, respectively. Average annual concentrations were 45.7±48.4 µg/m³ (PM<sub>10</sub>), 26.4±22.7...
Abstract Among the Organization for Economic Co-operation and Development (OECD) countries, South Korea has highest population exposure to PM 2.5 . Although country’s diverse reduction policies have improved pollution levels, concentrations still pose serious environmental health risks. Herein, we monitored physicochemical components, such as ion, metal, organic carbon/ elemental carbon (OC/EC), particle number concentrations, across different regions in January 1–December 31, 2021. The...
