If the radiation intensity is large, will make people dizzy, addicted to spit, weakness, memory loss. Indoor dust and combustion particles, droplets and other pollutants, and indoor air light ions, forming heavy ions. The former polluted air only one minute remaining, while the latter can persist one hour, thus strengthening the adverse effects of heavy positive ions are: headache, irritability, fatigue, high blood pressure, listlessness, lack of a recession, reduced working capacity , insomnia.

Different types of fuel, 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.
