Abstract

Our laboratory investigation aimed at assessing to what extent suspended particles could adsorb formaldehyde, allowing it, when inhaled, to penetrate deeper into the lung. We used two types of pure soot, N-220 and N-660 (the former being a highly active oil furnace soot with smaller particles and a larger surface area than the latter), because of their chemical inactivity and the adsorptive properties. The results obtained in experimental conditions showed that soot particles could bind 2.3 to 50.2% of formaldehyde, depending on the particle size, relative humidity, amount of particles and the duration of the contact. The recovery of formaldehyde from the particles was also tested. Further investigation is planned under realistic conditions.
