Deadly Gas

               Air pollution poses a massive threat to the public and is an issue that needs to be dealt with when it arises or many people could become sick or even die. This is exactly what happened in France in 1952 where over 150,000 people went to the hospital and 4,000 people died from what was eventually dubbed, The Great Smog.
               Scientists are looking for disease caused by particles often way too small to see with the human eye. These particles come from many sources such as power plants, factories, homes and cars, and even forest fires. If a person breathes in these particles they can move deep into your lungs where they can enter your bloodstream. The blood can carry these particles anywhere in your body even your brain and they trigger inflammation anywhere they go. This is why making sure the air is clean is such a huge problem because it only takes a small amount of particles to harm our bodies. High traffic roads are a very prominent source of pollution. Research has shown that people who live near areas with a lot of traffic related air pollution are much more likely to get Alzheimers Disease than people who do not.
               Air pollution is a massive threat to public safety and if it is not quickly noticed it can lead to the sickness and death of many people which is why it is such a big problem.
