Observe this certificate and try to give answer for the following question: For which type of vehicle pollution under control certificate has been issued?

The contamination of harmful and poisonous substances in the air is called air pollution. Pollution under Control Certificate is a certification mark issued to vehicles that pass the Pollution under Control Test. The certification indicates that the emissions coming from the vehicle does not exceed the standard pollution norms that means that the vehicle does not in any way contribute to pollution beyond specified limits. The pollution under control certificate is issued for the automobiles such as two-wheelers, three-wheelers, and four-wheelers which consume diesel, petrol as a fuel.

Observe this certificate and try to give an answer to the following question: What is the emission test? What components are tested in the pollution check-up centre?

Air pollution is the contamination of the environment by impurities that may have harmful impacts on the living and the nonliving components of the environment. Carbon monoxide, hydrocarbons, sulphur dioxide and nitrogen oxides, etc., are the pollutants which are released by the vehicles and mix the air to cause air pollution. To control the emission of these gases emission test is done by the check-up centre. The testing that determines the level of air pollutants released from the exhaust of automobiles is known as emission test. The following components are tested in the pollution check-up center: Carbon monoxide Hydrocarbons The petrol is hydrocarbon made up of hydrogen and carbon. These two elements are readily mixed with oxygen and therefore cause air pollution. Carbon monoxide is a poisonous gas. It is produced by incomplete combustion of fuel in industries, motor vehicles. When inhaled, it combines with haemoglobin and reduces its oxygen-carrying capacity.

Observe this certificate and try to give the answer to the following question: What will happen if Carbon monoxide (CO) and Hydrocarbons (HC) readings are higher than the permissible limits reading?

Carbon monoxide is a very poisonous gas. It is produced by incomplete combustion of fuel in industries, motor vehicles, kitchen, smoking, etc. The carbon monoxide causes a hazardous effect on the health and environment if the readings are higher than the permissible limits reading. Effect on the environment: When carbon monoxide is emitted into the atmosphere, it affects the amount of greenhouse gases, which are linked to climate change and global warming. Effect on health: The carbon monoxide combines with the haemoglobin and reduces its oxygen-carrying capacity. This leads to breathing problems, cardiac diseases, laziness, etc. The hydrocarbons are produced naturally during the decomposition of organic matter. These are also generated during the burning of fossil fuels such as coal and petroleum. Methane and chlorofluorocarbons are the most abundant hydrocarbons in the atmosphere. Effect on the environment: Methane oxidises into carbon dioxide (CO2), increasing the amount of CO2 in the atmosphere and adding to the greenhouse effect and global warming. The chlorofluorocarbon causes the ozone layer depletion. Effect on health: Contamination of petroleum causes an adverse effect on the genetic health, immune system, and endocrine system. Some of these hydrocarbons are toxic, with the potential to cau se cancer.
