Does Traffic Pollution Cause Asthma?

Authors Avatar

Introduction

In my case study, I aim to research whether there is a correlation between asthma and traffic pollution.  I will show this by identifying traffic pollution, asthma and its causes.  I will present this through graphs and text which include, how asthma is caused and if traffic pollution has an effect on it or not.  I will study a range of articles and arguments whether people believe that traffic pollution is one of the causes of asthma.

Asthma

Symptoms of asthma occur when a person with asthma comes into contact with something that irritates airways.  Airways will then tighten, swell and become narrower. Sticky mucus and phlegm builds up in the airway lining making them even more narrow and irritated. The airways are small tubes that carry air to and from your lungs.

 

This diagram shows a normal air tube and then an inflamed one.

How Much Pollution is let Out from Cars?

For every kilometer the average car is driven, 0.24kg of air pollution is produced.  This is a large amount, and it is damaging our atmosphere.  

The different gases which are let out of cars are;

  • Carbon monoxide – a colourless, odorless gas.  When reacts with oxygen it forms, Carbon Dioxide.  It is a very poisonous gas.

  • Hydrocarbons – an organic compound consisting entirely of hydrogen and carbon.

  • Nitrogen monoxide – reacts quickly with oxygen in the air to form nitrogen dioxide. ...

**** Some good data and other researched information but this essay has a disjointed feel and there are far too many variables for any meaningful conclusions to be made.
