People indoors physiological metabolism, daily life, work study and other activities, which can produce a lot of pollution factor. Fuel combustion is one of the major sources of pollution indoors. Different types of fuel Shenzhen home in addition to formaldehyde, even the same fuel of different origin, its chemical composition and the composition and quantity of the products of combustion will be different. But, in general, the products of combustion of coal particulate matter, SO2, NO2, CO, PAHs based; combustion products, liquefied petroleum gas to NO2, CO, polycyclic aromatic hydrocarbons, formaldehyde based. Briquettes in no vigorous combustion stove chimney, kitchen air SO2 reach 17mg / m3, usually around 3mg / m3; NO2 up to 50mg / m3, usually around 4mg / m3; CO up to 300mg / m3 or more, usually about 20 ~ 30mg / m3; particles in about 1 ~ 2mg / m3. When there is a chimney, SO2 can be reduced of about 0.05mg / m3; NO2 at 0.6mg / m3; CO about 6mg / m3; particulate matter about 1.4mg / m3. LPG combustion and indoors without ventilation equipment, SO2 from not detected to 0.05mg / m3; NO2 of 10mg / m3 or more; CO for 3 ~ 4mg / m3; particulate matter was 0.26mg / m3; formaldehyde up to 0.1 ~ 0.4mg / m3.

Indoor air pollutants can be divided into respirable particulate matter, but also a major carrier carcinogenic chemical contaminants and radioactive substances. Biologically active particles bacteria, viruses, pollen, etc. in addition to formaldehyde, is the culprit of most respiratory infections and allergic diseases. In indoor environments, especially in poorly ventilated, overcrowded environment, some pathogenic microorganisms easily spread through the air, so susceptible to infection. Some common viruses, bacterial diseases such as influenza, measles, tuberculosis and other respiratory diseases are spread by air in the room. SARS virus outbreak fact also indicates that indoor biological pollution should not be underestimated!
