Indoor Air Quality: 1. Introduction: Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. People spend about 90% of their time indoors. Many people spend their entire working day inside an office, shop, factory, or other facility. In some indoor environments, poor air quality has been blamed for physical symptoms and complaints such as headaches, eye irritation, and coughs. These physical symptoms and complaints can affect people’s health, comfort, job satisfaction, and work performance. In recent years, people have become more aware of potential health and comfort problems that may be associated with poor indoor air quality. This is partly due to the move to more tightly sealed buildings, the implementation of energy conservation programs, and the growing use of laser printers, photocopiers, and other sources of indoor air contamination. A greater general awareness of environmenta l issues may also play a part. Indoor air pollution is a serious problem in many developing societies. In homes where open fires burn, especially when the climate is cold, the pollution from the fires accumulates and exposes the inhabitants, especially women, to the risks associated with smoke inhalation. The result can be serious lung disease and an increased risk of cancer, as occurs in some parts of China, India, Bangladesh, Nepal, Bhutan etc among women who tend fires in homesShow MoreRelatedIndoor Air Quality ( Iaq )3184 Words   |  13 Pages Indoor Air Quality (IAQ) as a causal factor in disease propagation Introduction: A healthy indoor environment is an essence for a comfortable, healthy and productive life.
