The estimation of formaldehyde concentration in indoor air

Abstract

This article is devoted to the measurement of formaldehyde emissions from furniture materials in the classes of St. Petersburg Polytechnic University and kindergartens. An important task of society is to preserve the health of children and students, since they spend a large amount of time in public buildings. The safety of indoor air depends from the materials of which the finishing materials and furniture are made. Formaldehyde is a priority hazardous substance released into the air of confined spaces. Studies were conducted not only for the amount of formaldehyde in the air in the room, but also for the materials from which the furniture was made. Small-sized installation was made for sampling formaldehyde emissions from furniture materials. These emissions were investigated by the photometric method with acetyl acetone reagent. The installation can be used to study the emissions parameters of other components that can be separated from finishing materials and furniture.
