Indoor Air Environment—Hygienic Factors and Limits

Author(s): Thomas Alsmo

Complaints on the indoor environment of the residents in recent decades have become
a common problem in the Swedish housing. The buildings themselves are said
to be the cause of problems, and it is given a vague picture of both the exposure and
the effect of the problems. The symptoms that residents and users state are often
common in the population such as headache, fatigue, mucosal disorders and skin
problems. It must be considered that the air that people routinely inhale contains
impurities of various kinds, both in- and outdoors. An important source of contamination
indoors is the microorganisms that are pathogenic, so called agents. Examples
of infectious agents are viruses, fungi, bacteria and protozoa. The purpose of this
project is to examine whether a physical measurement is possible to obtain for identifying
a possible threshold level of air pollution in the indoor environment. In this
study, carried out through physical measurements, the results show major deficiencies
in the Swedish school environment. If we study the emissions in the important
health-related size range of particles larger than 5.0 microns, before and after measures,
the environmental benefits are clarified since over 90% of contaminants larger
than 5.0 microns have been eliminated.
