Sunlight-based Method Developed to Measure Ultrafine Dust in the Plant

SEOUL, April 7 (Korea Bizwire) — The National Institute of Environmental Research said Tuesday that it had recently developed a Solar Occultation Flux (SOF) method that uses sunlight to measure the ultrafine dust-causing materials such as nitrogen oxide that are fugitively emitted not only through chimneys but also through a variety of production processes. Fugitive [...]
