Dust build-up on surfaces in the indoor environment

摘要: Abstract The concentration and the composition of dust in indoor environment has been associated with reported symptoms sick building syndrome. Levels airborne concentrations particles are well known. However, relation to on surfaces for office environments not described. In this study, 662 measurements were performed surface hard 19 buildings within Harvard University based a sticking gelatine foil method. measure is covered area as percentage. three offices, build-up was measured period five days.
