This paper is the presentation of the authors'work in the THADE project. Their objective has been to review legislation and guidelines on air pollution and air quality in European dwellings and outside Europe too.

To MAP means "to make available to people", it is to communicate information in different parts of Europe, mainly to the professional. The information to diffuse here are asthma, allergies and bronchitis.The MAP tool will be downloaded from the internet.

To give some rules to the construction industry, a new standard on the ventilation was issued in Portugal (NP 1037-1:2002). This standard deals with natural ventilation. Some researchs are being carried out to assess impact of the natural ventilation on indoor environment.

The aim of this 24 months' project is to create a European network in the area of indoor air pollution with the listing of priority substances to be regulated indoors, recommendations, legislation... at world scale.

This study aims to assess the relationship between building and allergen exposure, and between dwellings and pollutants enhancing allergen response. Kind of allergens and pollutants are described with their sources, and measured levels. The authors conclude that the role of the medical corporation in the future will be very important for the improvement of the indoor air quality.

The author describes the most important indoor air related health determinants and a table gives information on the source characterisation of health determinants indoors, their control method along with examples of actions that could be taken by national level bodies or societies.

ETS has been recognized as a toxic agent in 1986 that could cause lung cancer, effect the pulmonary function, later on, other studies and surveys found association between ETS and asthma, with risk of coronary heart disease. This paper is a review of those different studies.

In developed countries, allergens, gas cooking and tobacco smoking represent a majorrisk, whereas in many developing countries wood stoves and indoor fuel cooking are moreimportant.Building-related illnesses represent another problem. The effects of indoor pollution are getting worseby poor living conditions and poor ventilation.

This paper is a review of data collected in European dwellings on particulate matter (PM), nitrogen dioxide (NO2), carbon dioxide (CO2), carbon monoxide (CO), volatile organic compounds (VOCs), formaldehyde, dampness/mould and dust mites at home. Related health effects are summarized in this review too, along with some results not yet published from two Italian indoor air studies.

For that study, 200 children in Manchester were recruited to assess their asthma status, their indoor environment was analyzed. Levels of a variety of indoor agents, reported as important factors in the development or the exacerbation of respiratory troubles were examined. Results are presented.
