Frequently, problems result from new occupation of an old buiding when the building is operated or maintained in a manner that is inconsistent with its original design or prescribed operating procedures. Sometimes indoor air problems are a result of poor building design or occupant activities.
complaints may result from other causes. These may include an illness contracted outside the building, acute sensitivity (e.g., allergies), job related stress or dissatisfaction, and other psychosocial factors.
Some possibilities are:- Inadequate ventilation: In the early and mid 1900's, building ventilation standards were very different these reduced outdoor air ventilation rates were found to be inadequate to maintain the health and comfort of building occupants. Inadequate ventilation, which may also occur if heating, ventilating, and air conditioning (HVAC) systems do not effectively distribute air to people in the building.
Chemical contaminants from indoor sources: Most indoor air pollution comes from sources inside the building. For example, adhesives, carpeting, upholstery, manufactured wood products, copy machines, pesticides, and cleaning agents may emit volatile organic compounds (VOCs), including formaldehyde. Tobacco smoke contributes high levels of VOCs, other toxic compounds, and respirable particulate matter.
Combustion products such as carbon monoxide, nitrogen dioxide, as well as respirable particles, can come from unvented heaters,
gas appliances etc.
Chemical contaminants from outdoor sources: The outdoor air that enters a building can be a source of indoor air pollution. For example, pollutants from motor vehicle exhausts; plumbing vents, and building exhausts.
Biological contaminants: Bacteria, molds, pollen, and viruses are types of biological contaminants. These contaminants may breed in stagnant water that has accumulated in ducts, humidifiers and drain pans, or where water has collected on ceiling tiles, carpeting, or insulation. Sometimes insects or bird droppings can be a source of
biological contaminants. Physical symptoms related to biological contamination include cough, chest tightness, fever, chills, muscle aches, and allergic responses such as mucous membrane irritation and upper respiratory congestion. Legionella, has been a particular problem of late.
These elements may act in combination, and may supplement other complaints such as inadequate temperature, humidity, or lighting.
Of course theres also Radon and Asbestos... the list goes on..
When was the walls painted and what paint was used? Some gloss paints or even emulsions can give headaches and tight chests etc.
I think there is enough for you to investigate!
