Question

How does emission lead by vehicles affect humans?

Answer 1

Hint: One of the major causes of environmental pollution is the emission from vehicles. The emission can contain gaseous pollutants as well as particulate particles. The gases emitted by the vehicles are majorly oxides of carbon and nitrogen. These gases are potent in causing serious health hazards to all the living beings present on the earth.

Complete answer:
To solve this question, we must know the emission of vehicles. The vehicles run on fuels. The fuel on combustion liberates a large amount of energy which is the driving force for the vehicles.
- Any organic compound on combustion emits carbon dioxide. In the case of vehicles, the combustion of gasoline/petroleum/diesel takes place. This emits a huge amount of carbon waste in the form of dioxide and monoxide which are very harmful to human beings. Carbon dioxide is one of the major greenhouse gasses which is causing global warming. Carbon monoxide can cause severe respiratory disorders as it can bind easily with haemoglobin.
- The other harmful gases emitted by the vehicles are oxides of nitrogen and sulphur. This gas causes severe respiratory disorders like severe asthma, bronchitis and other lungs related disorders.
- Lead is the most harmful particulate pollutant that is present in gasoline. Lead poisoning is harmful and can cause various long-lasting problems like abdominal pain, headache, memory loss, tingling hands and feet, kidney and brain disorders etc. This problem arises if the expose of lead takes place for a longer duration.
- The other particulate materials emitted from the vehicles are in the form of smoke, dust which cause dense smog which affects visibility and causes several accidents.

Note: In order to prevent the hazardous effect of the emission, one should rely on electric vehicles which do not pollute the environment. Also, the use of public transport and carpooling can affect the environment and the health of living beings in a better way. Many countries have adopted the methods like cycling and walking to the workplace. These are beneficial in reducing air pollution to a greater extent.
