How does a car cause air pollution?

Answer 1

There are many different causes of car pollution. Exhaust fumes on older cars for example are a cause of car pollution.

"older" cars... Actually, no. All internal-combustion engine vehicles produce polluting gases, though new ones are designed to be far more fuel-efficient and less polluting, for a given power output, than in the past.

Answer 2

Cars emit pollutants like carbon monoxide, nitrogen oxides, and particulate matter when they burn gasoline or diesel fuel. These pollutants contribute to smog, acid rain, and respiratory health problems when released into the atmosphere.

Answer 3

An average small car, with an engine size of 1.6 litres produces about 200 grams (0.2 kilograms) of carbon dioxide (CO2) Answer: A car (diesel or gasoline) produces about 3 kg of carbon dioxide for each liter of fuel burned. Additionally there are small amounts of unburned hydrocarbons and NOx in the exhaust.

Answer 4

The causes are fairly simple:

* Too many vehicles carrying too few people * People wanting vehicles bigger than they require * Poor driving strategies that see to many short trips when one well planned trip would do * Low use of public transportation * Poorly maintained vehicles * Poor driving habits * Poorly designed cities that require commuting

Answer 5

car emits carbon dioxide in air and some harmful gases too. Gases like carbon dioxide,carbon mono oxide, sulfur etc .This make lead to air pollution.due to this

we are facing the crisis of global warming

Answer 6

First we must understand that pollution is the contamination of an objects surrounding, which may occur from natural sources or be caused by man-made objects or materials. The contaminants are only considered pollution when there is an excess in terms of their customary amounts. The pollution that causes harm to our environment is made up of chemical substances such as Carbon Monoxide(organic substance formed by decomposition), Nitrogen Dioxide(brown poisonous gas), Sulphur dioxide(toxic gas), Benzene(liquid carcinogenic hydrocarbon), Formalehyde(poisonous gas), and Polycyclic Hydrocarbon(aromatic hydrocarbons) to name a few. They can lead to reduced lung functioning such as Asthma attacks or respiratory symptoms like coughing or wheezing, headaches and dizziness, disruption of the endocrine system, reproductive system or immune systems, cardiovascular difficulties or cancer to any human in contact with the pollution. Effluences disrupt our ozone layer which shields us from the harmful ultraviolet radiation distributed by the sun.

Answer 7

cars cause pollution because of the carbon monoxide coming out of the muffler.

it is very bad for the environment

Answer 8

Carbon Monoxide. For instance, if you let your car running in the garage you could die of CO poisoning.

Answer 9

air pollution

Answer 10

Carbon monoxide is the main one.
