Field survey on indoor air pollution and factor causing symptom in sick houses

Sick Building Syndrome or Sick House Syndrome (SBS/SHS) has become a serious problem in Japanese daily life.This survey was conducted in 53 houses in Miyagi prefecture during four summer seasons from 2000 to 2003 to understand the states of indoor air pollution and occupants health conditions in dwellings suspected as Sick Houses.It appears that the relationship between chemical substance concentration and subjective symptoms is not clear and the causes of symptoms are different between individuals. In future, it isnecessary to analyse relationships among building conditions, indoor pollutants and occupants symptoms, with a multivariate statistical model.
