People spent up to 90% of their time indoors (EU, 2005). Consequently,factors impacting the indoor air quality such as dampness,presence of molds and chemical exposures can have a considerable influence on human health. Concerns about possible health effects of indoor pollution with regard to carcinogenic and non-carcinogenic effects like asthma, allergies or non-specific symptoms from eyes, upper airways and facial skin are increasing. Such non-specific symptoms are occasionally referred to as ‘sick building syndrome’(SBS) (Sahlberg, 2012). Most indoor pollutants consist of chemicals
stemming from various sources including outdoor, indoor combustion sources such as tobacco smoke, heating or cooking, and burning of candles. Other sources may include emissions from furniture and construction materials, the use of cleaning products, air fresheners,indoor pesticides, and other consumer products. In addition, microbiological contaminants which may induce allergies and asthma require careful consideration as potential indoor air pollutants
