Poisonous gas likeHydrogen Chloride
Ammonia & Hydrogen Cyanide
Burning of Plastic Materials

Harmful effects on the respiratory system
Nicotine Causes addiction.
Causes Illness such as bronchitis, throat cancer and lung cancer.
Tobacco tar Blackens the lungs and cause them less
efficient. Damage alveolus cells. Causes lung cancer.
4
Acid Corrodes lung cells.
Causes illness such as coughing, asthma, bronchitis.
Carcinogen Stimulates the growth of cancer cells, causing lung cancer and throat cancer.
Acidic gas from factories Damage breathing channel and lungs.
Vehicle fumes Reduce the ability of blood to transport
oxygen and cause death due to severe cases.
Haze Damages lungs.
Burning of plastic materials Corrodes the breathing channel.
5
Diseases affecting the
respiratory system
Emphysema
o It happens as a result of abnormal growth in the cells that lines the tiny air channels
in the lungs causing these channels to become blocked.
6
o This growth causes carbon dioxide trapped in alveolus and cause the alveolus
to burst.o Bursting of the alveolus cannot be
repaired.
Bronchitis
o Bronchitis is inflammation of the epithelium (cell layer) of the bronchus
caused by fine particles that float in the air that are mostly found in cigarette
smoke.
7
Lung cancer
o Cancerous lung cells are unusual cell growths in the lungs.
8
o Carcinogen, the chemical substance found in cigarettes, is the main cause
of the lung cancer.
9
Asthma
o Asthma is a type of disease caused by the inflammation of the breathing channel.o The breathing channel of a patient
suddenly becomes narrow.o Asthma may caused by dust (air
pollutant) , smoking or cigarette smoke.
10
Improving the quality of air
o Use air cleaning system to dissolve poisonous toxic gases like sulphur dioxide and nitrogen dioxide in water before it was
released to the atmosphere.o Stop Smoking to prevent the release
cigarette smoke in the air. o Install catalyst convertors on vehicle
exhaust to reduce the release of dangerous gases like carbon monoxide.
o Install electrostatic precipitators on factory chimney to remove pollutant.
