AIR POLLUTION AND THE HEALTH EFFECTS

Air is the ocean we breathe. Air supplies us with oxygen which is essential for our bodies to live. Air is 99.9% nitrogen, oxygen, water vapor and inert gases. activities can release substances into the air, some of which can cause problems for humans, plants, and animals. There are several main types of pollution and well-known effects of pollution which are commonly discussed. Each of these problems has serious implications for our health and well-being as well as for the whole environment.

Air pollution can affect our health in many ways with both short-term and long-term effects. Examples of short-term effects include irritation to the eyes, nose and throat, and upper respiratory infections such as bronchitis and pneumonia. Other symptoms can include headaches, nausea, and allergic reactions. Long-term health effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys. Continual exposure to air pollution affects the lungs of growing children and may aggravate or complicate medical conditions in the elderly.

According to the data of WHO every year an estimated 3 million people die because of air pollution or about 5% of the 55 million deaths annually world wide. 1,500 millions of the premature deaths occur in Asian cities. Many more suffer serious health effects from air pollution. The working lives of many are shortened by health problems from breathing filthy air. Six of the world’s 15 most polluted cities are found in Asia. The top positions go to 1. Katmandu, Nepal, 2. New Delhi, India, 3. Jakarta, Indonesia together with Chongqing, China. 4. Calcutta, India.

In many countries in the world, steps are being taken to stop the damage to our environment from air pollution.

  • Scientific groups study the damaging effects on plant, animal and human life.
  • Legislative bodies write laws to control emissions.
  • Educators in schools and universities teach students, beginning at very young ages, about the effects of air pollution.

The first step to solve air pollution is assessment. Researchers have investigated outdoor air pollution and have developed standards for measuring the type and amount of some serious air pollutants. Scientists must then determine how much exposure to pollutants is harmful. Once exposure levels have been set, steps can be undertaken to reduce exposure to air pollution.These can be accomplished by regulation of man-made pollution through legislation. Many countries have set controls on pollution emissions for transportation vehicles and industry. This is usually done to through a variety of coordinating agencies which monitor the air and the environment.

Prevention is another key to controlling air pollution. The regulatory agencies play an essential role in reducing and preventing air pollution in the environment. In addition, it is possible to prevent many types of air pollution that are not regulated through personal, careful attention to our interactions with the environment. Such as :

  • Most household products come with instructions about safe use,
  • Building materials should be reviewed for potential harmful effects.
  • Adequate ventilation is also a key to controlling exposure to indoor air pollution.
  • Restricting smoking is an important key to a healthier environment.  Legislation to control smoking is in effect in some locations, but personal exposure should be monitored and limited wherever possible.

THE CONCLUSION

Air pollution is a problem that has many negative effects for our body health, earth, etc. Only through the efforts of scientists, business leaders, legislators, and individuals we can reduce the amount of air pollution on the planet.
