Sick house syndrome

However, when formaldehyde-sodium bisulfite, etc., are used as a reducing agent component, formalin is generated from the resultant aqueous emulsion. Formalin is assumed to be the main cause of the sick house syndrome. This is a highly undesirable phenomenon from the hygienic standpoint. 

Sick building syndrome (or as it is sometimes called Sick House Syndrome) is directly connected to lAQ and it is simply due to the poor indoor air quality .

Figure 2 shows the market transitirm of industries related to photocatalysis, based on a survey by the Photocatalysis Industry Association of Japan. This data represents the sales volume for companies that are members of the Photocatalysis Industry AssociatiOTi of Japan. The sales volume greatly increased during the past decade, especially for the cleanup application involved in photocatalytic water and/or air purifiers. This trend indicates the increasing number of people who are interested in environmental issues such as food poisoning and sick house syndrome. Moreover, the swine influenza...

Phenol and other volatile organic compounds were measured in the air of 50 homes or apartments in Finland (Kostiainen 1995). The average concentration was 0.23 ppb, with a range of 0-0.77 ppb. Phenol levels were not significantly higher in houses in which people complained of symptoms that resembled those of a sick building syndrome. 

The indoor air in very old houses may contain organics at trace levels due to what is known as the sick building syndrome. The presence of low molecular weight organic compounds is attributed to degradation of wood releasing hydrocarbons, aldehydes, and ketones. 

Despite extensive use, animal models have not contributed significantly to AIDS research. While monkeys, rabbits, and mice can be infected with HIV, none develops the human AIDS syndrome. Of over 100 chimpanzees infected with HIV over a 10-year period, only two became sick. Because chimpanzees turned out to be poor models for AIDS, and were expensive to maintain, all of the animals were faced with euthanasia (a euphemism for being killed). In 1997, the National Research Council recommended a solution. For all of the chimpanzees housed in research facilities throughout the United States, a breeding moratorium was introduced and specific steps taken toward making long-term care available for the primates. Animal rights supporters applauded the decision on the basis of moral responsibility.
