destined to recreational or social activities (cinemas, cafes, restaurants, shops, sporting
structures, etc.) and finally public and private transport means (auto, train, airplane, ship,
etc.) " (ARPAV Regional Agency for the Prevention and Environmental Protection -
Environmental Glossary (2005)).
For the definition of indoor air pollution it refers also to definitions that are in the
dictionary IAQ (International Society of Indoor Air Quality and Climate). Both in national
and international field, the indoor air pollution is not regulated by real legislative
references, as instead happens for the outdoor air pollution (of the external environment).
Nevertheless, the directive 89/106/CE of the European Council on the construction
products pay a particular attention to this thematic, in fact it considers sanitary and
environmental aspects and instructs the CEN to elaborate harmonized regulations and
methods of test concerning the quality of the air inside buildings.
The interactions between environment and health are object both of the "VI° Community
Environment Action Program", founded by the Decision 1600/2002/CE, and of the
following one “Communication from the Commission to the Council the European
Parliament and European Economic and Social Committee:
A European Environment
and Health Strategy
" (COM (2003)338). In the "VI° Community Environment Action
Program", among main defined actions it is present the part regarding the respect of the
problem of the quality of the air inside the buildings and the relative impact on the human
health.
From a point of view of a development of an integrated system of information, since
1999 the World Health Organization (WHO) has started a series of activities, among
which the study of a set of environment and health indicators for the European Countries
with the activation of the Project ECOEHIS (Development of Environmental and Health
Indicators for the EU countries), articulated in various matters with an environmental
thematic defined traditional, as the atmospheric pollution, the water pollution, the
acoustic pollution but also the indoor and housing pollution. In this way a list of common
fundamental indicators is now available, that all countries of the European Union are
able to calculate available and that can be then included in the European Informative
System on Environment and Health.
The World Health Organization (WHO), has elaborated guidelines for the quality of the
air due to mould and micro-organism (guidelines for indoor air quality: dampness and
mould) (2009) and the guidelines on the indoor air quality ("WHO guidelines for indoor
air quality: selected pollutants") (2010) where it analyzes the dependent factors of
pollution from chemical and physical pollutants. The European Union organized the
project of research COST Project 613 "Indoor Air Quality and its Impact on Man" (1997),
and has faced a description of the thematic specifications of the indoor air pollution.
At the Italian national level, a technical requirement for the control of the quality of the air
indoor has not been worded yet. The Ministry of the environment in the first years '90
have constituted an Indoor Committee with the purpose to define limits of reference for
the control of the quality of the air in the confined environments. An important tool for
the safeguard of the public health results to be the Law n° 3/2003, art.51 on "Safeguard
of the health of non smokers", came into force on January 10, 2005. This law extends
the smoking prohibition in all closed places, except those that are private not opened to
consumers or to the public, and those reserved to smokers.
It is also necessary, for completeness, to quote UNI Standard 10339, UNI EN Standard
15251 and UNI EN Standard 13779 coping with the thematic of the quality of the indoor
air environments correlated to the planning and verification of the operation of the fittings
of ventilation and air conditioning of confined places.
In each of these the term "indoor air" is reported. In the UNI Standards 10339 and UNI
EN 13779 (with ref. to UNI EN 12792) are brought the classification of the indoor air. In
the UNI 10339 are classified the quality of the indoor air in 3 typologies, correspondent
