Formaldehyde In Indoor Air:
A Public Health Problem?
Author(s)
S. Viegas & J. Prista
Abstract
Formaldehyde was the first air pollutant, which already in the 1970s emerged as
a specifically non-industrial indoor air quality problem. Yet formaldehyde
remained an indoor air quality issue and the formaldehyde level in residential
indoor air is among the highest of any indoor air contaminant.
Formaldehyde concentrations in 4 different indoor settings (schools, office
buildings, new dwellings and occupied dwellings) in Portugal were measured
using Photo Ionization Detection (PID) equipment (11,7 eV lamps).
All the settings presented results higher than the reference value proposed by
Portuguese legislation. Furthermore, occupied dwellings showed 3 units with
results above the reference.
We could conclude that formaldehyde presence is a reality in monitored
indoor settings. Concentration levels are higher than the Portuguese reference
value for indoor settings and these can indicate health problems for occupants.
Keywords: formaldehyde, indoor air, indoor settings, schools, office buildings,
dwellings.
