Summary- A new study has shown that collectively, people exposed to increased levels of air pollution are at greater risk of stroke, heart attacks and cognitive deterioration. One experiment found that 20,000 women over a decade of living in a highly polluted area such as a city, had accelerated declines in the measures of memory along with attention span. Another study showed that days with higher concentrations of traffic pollutants, increased the risk of stroke. Short term effects of pollution remain unclear, hoever long term effects of inhaling pollutants have shown damaging, potentially severe effects when on days when the federal air quality index states "moderate" pollution days, this can correspond to more danger than originally suspected. Not only are stroke and heart attack risks increased, but also dementia, hypertension and brain function as well which can explain the rise in diseases such as Alzheimer's in the past decade. However, some believe that this increase can be due to improved medical technologies, allowing for better methods of detecting these diseases. Researchers have found a 34% higher risk at times when pollution levels climbed from "good" to "moderate". The effects were particularly strong when researchers looked at levels of black carbon and nitrogen dioxide; two agents that infiltrate the body

's tissues.Opinion- This article provided a great awareness to everyone about pollution and how severe it's effects can be on the human body. Not only is it a serious health factor to us, but it's a serious danger to the environment and ecosystem. With the information founded by these studies, I believe we would be able to come up with preventative ways to help limit the effects of pollution on our bodies. Those who live in polluted areas such as the city, 
should be aware and try to manipulate their life style in order to provide the healthiest choices for their bodies considering there is not much we can do to reduce the levels of pollution within the city. This would include improving eating habits (i.e healthier foods, smaller portions, etc.), increasing levels of exercise, and reducing stress as much as possible. These can possibly help limit the damaging effects pollution has on our population until a solution is created to take care of the matter.
