research of IAQ．The paper attempts to demonstrate the difficulties in improving IAQ completely，the
necessity and the feasibility of the research of BPAQ at present．
2．DIFFICULTY To SToP AND DISPEL THE INDOoR AIR PoLLUTIoN CoMPLETELY
2．1 Complexity and Stubbornness of the Indoor Material Pollutants
More and more new materials and technique are used in building in recent years．Countless ofchemical products are used as bagic material，bond or additive in the fit—up，furniture，electric equipment products,daily chemical industry products，fabric，books，toy，food，cines etc．And for the movements such as cooking，smoking and sweeping，hundreds of pollutions such as VOCs，CO，ammonia，dust ozone，bacterium，fungi，virus，peculiar smell，radioactive radon and human body’s contaminators etc．is full of indoor air．
The concentration will be low as the time flies；some pollutants still exceeds the health criterion．The Environmental Monitoring Center of Indoor Environment once entrusted by consumer to measure residential room．found that the density of ammonia was as 7 times as national standard in the indoor air，and it can volatilize until 20 years ，that is to say it will do harms to the inhaleIitant for 20years．Radon，always considered being the second pathogeny of the lung cancer,which has very long time to release．Once appears，the harm will coexists．For example，as shown in the Qingdao Municipal Centers for Disease Control，the concentration of some pollutants of decorated house is till above the standard though after ten years f91．The phenomenon that pollutant content in buildings，fitment and furniture materials exceed standard has not been prevented，which is the most seripus problem，and this is often reported in regional building materials markets in recent years．
Some other pollutants，though known，are very difficult to clean out，such as radon from the antifreeze in concrete．And some office equipments and home appliances will g
…… It is our great pleasure to host the 2 International Conference on Built Environment and Public Health(BEPH2004)on December 6-8，2004，Shantou，China．
This conference is the continuation of the first conference that was held in Changsha，China in December，2003．This series of conference were initialized by Chinese Society of Environmental Sciences，HunanUniversity and other organizations in China，sponsored by number of nternational and national organizations of China，aiming at providing a platform for academic exchange and knowledge transfer or researchers，practitioners in the multidisciplinary field of built environment and public health．Professionals from architecture，HVAC engineering，building material，public health，environment monitoring，environmental science and engineering had good exchange in their research work and understanding in the related field in the first conference，which made it a successful one．
The Proceedings contain about 1 00 papers that have been reviewed by our members of Programming Committees and other expels．These papers have been from 1 0 countries and regions in the field of built environment and public health．Some of the papers represent the most recent advances in the field worldwide，most of the papers reflect the advances in related field in China，where the research and practice in the field of built environment and public heath has been developing more quickly than ever before．
We are very grateful to the valuable help and enthusiasm received from members of the International Coordinators，Program Committee and the generosity of the Co—organizers，the Sponsors，the Co。sponsors and the Suppo~ers in various forms。
