views of the mountains frequently aid in the rise of air pollution‚ by not allowing the smog to escape the city. Paired along with the entrapped city‚ Tehran has a very dry climate with little precipitation. Rain helps clean the air to an extent‚ however the wind that accompanies the rain helps push the smog out of the city. With the lack of rain and wind‚ Tehran is a virtual snow globe encompassed with smog. In 2011‚ studies by CNBC discovered out of the top ten cities in the world with the worst

Thus climate change looms as one of our most serious public health threats; yet few people are aware of the many dangers posed by a warming planet. These include: Air Pollution: Warming temperatures worsen smog pollution‚ which triggers asthma attacks and permanently damages and reduces the function of children’s lungs. Higher smog levels even contribute to premature deaths

GEOGRAPHICAL ISSUE Introduction The quality of the air we breathe directly affects our general health and well being. The regular monitoring and maintenance of air quality is‚ therefore‚ extremely important for our overall quality of life. A key environmental issue which Australia currently faces is reversing the degradation of our ambient (outside) and indoor air quality. Aside from affecting human health‚ the presence of air pollutants in high levels can also adversely impact upon wildlife and

Introduction When people think about air pollution‚ they usually think about smog‚ acid rain‚ CFC ’s‚ and other forms of outdoor air pollution. The health of many people is affected by chemical substances present in the air within buildings. We chose this topic to be more aware about air pollution these days because it is more harmful to our health. To know some idea on how to handle air pollution and the importance of protecting the environment. An expression implying that we live because we

air quality in major industrial cities was so polluted that by mid-day the air was so darkened that cars needed to use their headlights since it appeared as though the sky was at dusk. In 1948‚ a smog‚ which is a mixture between smoke and fog‚ settled over a small town near Pittsburgh named Donora. The smog lasted for five days‚ killing twenty people and sickening thousands. In order to address the growing concern over environmental pollution‚ the Clean Air Act of 1963 was passed. However‚ the Act
