Human activities, building components
Burning wood, gas or oil-based fuel in cooking or heating appliances is still the major source of indoor air pollution. Chimneys or air vents, if they do exist, are not always adequate. A certain amount of smoke always escapes into the room, especially when wind gusts and backdraughts return the result of the combustion process to the sender.
Also, blended into the cocktail of combustion gases are the seductive odours of the ladies' perfumes - not to forget - the fumes of furniture polishes, cleaning agents and room deodorisers.
Building materials and furnishings contain natural and man-made chemicals that emit gases for many years after the manufacturing process has ended. Formaldehyde, to name just one, is a toxic gas released from adhesives and resins in furniture, carpets and numerous other household products.
Moulds are biological contaminants. They are not alone, though. Many kinds of germs do fall into the same category. Allergic to cats? Your 'moggy' may as well be another source of a biological contaminant: animal dander. Before you blame your cat or dog, perhaps you should consider the many dust mites that quite happily live in your soft-furnishing and bedding, as the reason for your sneeze attacks.
