Study On Indoor Pollutions Of Volatile Organic Compounds In Japanese Northern Cold-region House And Research On Indoor Living Environment

The indoor chemical pollutants of the house is the great problem in the indoor air quanlity, and it also belongs to the field of subject overlapping. In our country this field is being begun to study just now. This thesis plan to do some exploratory research significantly.The problem of indoor chemical pollutants in Japan is studied later than American and Europe.It was begun to study in wide scopes in 1998. relative policy and laws had been made and appeared one after another in 2000. On the time-background ,it is much closer to the appearance of indoor chemical pollutants in our country and it must be well used for reference for our country.Firstly, author studied the policy system and the standard formation of indoor chemical pollutants of Japan deeply, and wish that we can have successful experiences to go by and make our country's relative policy and laws more system, more perfectly and more scientificly , and even put forward myself constructive suggestions.In this study, author had investigated the newly built houses in six cities, the sick houses in three cities and their residents suffering from multiple chemical sensitivity (MCS) in HOKKAIDO,and furthermore analyzed the present situation and the factor of influencing indoor chemical pollutant concentration of new house , the reason of the sick house and the diagnosis of MCS, therefore inquired into its improving measurement.In the laboratory, to contrast new absorption plaster materials(the necessary in-wall materials of indoor wall materials) with conventional plaster materials, the author tested the result of the absorption and attenuation to formaldehyde, in order to grasp the trends of new building materials of Japan.This article had studied completely the countermeasure to reduce indoor VOC in Japan, especially the new architecture laws that its new regulation will be carried out in July, 2003. The trends of low formaldehyde emission building materials and wood-products is emulated by us.This article will have the initiative significance and motive effect for the study of indoor chemical pollutant of house of my country.
