Does House Dust From Water Damaged Buildings Cause Stronger Responses Among Occupants Than Dust From Buildings Without Water Damage? Can Occupants' Sensitivity be Predicted by Biomarkers?

The study is focussed on two main questions:

1. The importance of dampness of the building and home dust as a factor of the subjects= responses.
2. Can measures used in KLINIR predict the subjects' responses to the dust?

This study therefore was arranged to test the following hypotheses:

1. Does dust in general cause inflammatory/body perceptions through e.g. an irritation symptoms index.
2. Does the dust include effective odorants which affects an IAQ index?
3. Does dampness increase the content of organic or inorganic compounds e.g. of microbial origin that causes the dust to be more reactive? (Differences between the two types of dust)
4. Is the sensitivity of the subjects explaining the responses to exposures in a, b, or c? (Subject group and sensitivity index)

As explorative investigations biomarkers for exposures and sensitivity for practical usage are tested.
