저용량 PM2.5 도입부 개발 및 성능평가

Design and Performance Evaluation of Low-Volume PM2.5 Inlet

Most particles capable of reaching the thoracic region of humans are in the size range below 10$\mu$m in diameter. Particles with a diameter smaller than 2.5 $\mu$m are deposited in large amounts in the alveolar region during mouth inhalation. The hazard caused by fine particles depends on their chemical composition and the site within the human respiratory system where they are deposited(Hinds, 1982). Therefore, the concentration of air borne fine particles is an important parameter for the evaluation of the degree of hazard in an atmospheric environment. (omitted)
