29 Apr Air pollution
Chemistry tuition classes in Miracle Learning Centre is very useful. If you do not understand chemistry, you must definitely attend the chemistry tuition class at Miracle Learning Centre. Let us learn about air pollution in this chemistry tuition lesson.
Your chemistry tuition teacher at Miracle Learning Centre will teach you about air pollution. When harmful substances are being released into the air, air pollution occurs. Natural causes of air pollution include rotting vegetation which gives out methane and volcanic eruptions which pollute the air with ash, dust and sulfur dioxide.
Sulfur dioxide is a harmful, colourless gas with a displeasing odour. Burning of coal and oil especially in power stations give off sulfur dioxide. Constant exposure to sulfur dioxide causes breathing difficulties, bronchitis, pneumonia and even lung cancer.
Chorofluorocarbons(CFCs) are chemicals which are used in aerosol sprays, refrigerators, air-conditioning systems and foam products. CFCs cause the thinning of the ozone layer in our atmosphere. As the ozone layer gets thinner and thinner, more and more ultraviolet rays that cause skin cancer and cataracts will reach us.
Carbon Monoxide is a poisonous, colourless and odourless gas. Incomplete combustion of carbon or its related compounds produces carbon monoxide. Exposure to carbon monoxide causes harmful effects such as headaches, brain damages or even death within a short period.
Oxides of Nitrogen are poisonous gaseous compounds containing nitrogen and oxygen. These gases are released into the air from the burning of oil and coal at high temperatures, power stations, industries and exhaust fumes from motor vehicles. Constant exposure to the oxides of nitrogen damages the lungs.
