Does Traffic Pollution Cause Asthma?

Extracts from this document...


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. Page 1 Asthma and the statistics for it in children Page 2 Which gases come out of cars Page 3 Correlation graphs Page 4 Is there a correlation between traffic pollution and asthma Page 5 Reasons why there would be Page 6 Reasons why there wouldn't be Page 7 Conclusion References 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. STATISTICS FOR ASTHMA IN CHILDREN * In 2005, 27 children (14 and under) ...read more.


If this was the case, this could make their lungs sensitive to things that could trigger an attack. Here is a news paper article written in 2001 which is trying to prove that 'Pollution could cause asthma' "Experiments using monkeys suggest that traffic pollution could cause asthma in children, rather than simply trigger attacks. But a British expert says there is plenty of evidence suggesting precisely the opposite. Scientists at the University of California at Davis studied the effect of repeated exposure to ozone - a constituent of traffic smog - on rhesus monkeys. They found that after living in an environment described as "similar to Mexico City" for only a few months, the young animals had developed symptoms of borderline asthma. These included reduced lung capacity, and an apparently increased sensitivity to the dust mite allergen, wheezing when exposed to it for short periods. Monkeys exposed on a regular basis to both ozone and dust mite allergen had more severe reactions, including decreased blood oxygen levels." ARGUMENTS Reasons why there might be a link between asthma and traffic pollution One of the most well-known impacts of air pollution is an increase in asthma attacks. The incidence of asthma appears to have more than doubled in the last 15 years. ...read more.


I have had asthma all my life, but recently, have not been having so much trouble with it - if the statistics are correct, and that traffic pollution is increasing, causing more people to suffer from asthma - I feel that this is wrong, due to the fact that my asthma is getting better. I live in a busy town, where I am sure that there is lots of pollution, and regularly go into town where there would be most pollution - thus, it should cause my asthma to worsen. However, seeing as it is getting better, I feel that there is no such correlation between asthma and traffic pollution. CONCLUSION In conclusion to the evidence in which I have found, I think it is proven that there is a slight link to traffic pollution causing asthma, however, it is not all that clear. Scientists are still researching to see if they can find a clear correlation, but as of yet, there is none. Asthma has been around for hundreds of years, before motorised transport was invented, such as cars and lorries. Therefore, we know that traffic pollution is not the cause of asthma, and that is more likely to be pollen or hay. Traffic pollution may help make asthma worse, or trigger off an attack but it is not the cause. ...read more.

4 star(s)

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.
