Air Pollution and Its Effects on Human Health

12-year old Hari was watching the news. The news reporter said, “Air pollution is the silent killer responsible for millions of deaths each year. What is even more alarming is that air pollution does not only cause respiratory problems. It has been linked to other life-threatening diseases from heart disease to cancer, etc.”

Curious Hari googled more about air pollution and found out that people who are abnormally sensitive to ozone AQI 51 - 100, experience respiratory symptoms, while sensitive people with heart and lung diseases face issues in 101 - 150 AQI range. Moreover, (101-200) and (201-300) can cause long-term inhalation and breathing issues in people with asthma or heart diseases. 

On more research, he found surprising results and told his mother that “People living in (301-400) AQI range can experience respiratory illness due to prolonged inhalation. While, in (401-500) range, even healthy people can see respiratory effects.”

Hari’s mother told him, “ Air pollution is likely to affect the whole population. Those most at risk from particle pollution exposure include those with heart or lung disease (including asthma and chronic obstructive pulmonary disease-COPD), older adults, and children. Research indicates that pregnant women, newborns, and people with certain health conditions, such as obesity or diabetes, may also be more sensitive to PM-related effects.”

She also added that air pollution affects not only lungs but skin, eyes, hair, heart, immunity, reproductive health, brain and mental health, etc.

“What can we do, Mom?” Hari asked.

“Air pollution is a serious global problem that gives rise to many diseases. Many of these diseases are preventable. Therefore, it is important to be aware of them and take steps to protect yourself from air pollution.” his mother replied.
