Indoor Air Quality. Indoor Air Pollution. Indoor air contains higher concentrations of pollutants than outdoor air (up to 70x). Indoor air pollution usually is a greater threat to human health than outdoor air pollution.. LT 7C: Describe the major outdoor and indoor air pollution problems, discuss the causes and effects of these problems and explain possible solutions to them..  . Outdoor Air Pollution. The presence of chemicals in the atmosphere in concentrations high enough to harm organisms, ecosystems, or human-made materials, or to alter the climate. newborns. . Rüedi. S*, . Proietti.

London, the capital of the United Kingdom, is notorious for air pollution. In fact, the word smog was first used in 1905 to describe the air in London. Smog is air pollution caused by sunlight acting on gases from automobile and factory exhausts. It sometimes hangs over cities in the United Kingdom. . what is the nature of the atmosphere. We live at the bottom of a thin layer of gases surrounding the earth called the atmosphere, which is divided into smaller spherical layers. In the troposphere, the layer closest to earth, about 75-80% of the earths air mass is found here.. Air pollution . -.  Harmful gases and tiny particles (like carbon monoxide, nitrogen dioxide and . sulphur. dioxide) when released into the air pollute the air. The smoke released from burning fuel, from factories and not to forget the motor cars are the major sources of air pollution. . Green Budget Europe Event. Dr. Aonghus McNabola. School of Engineering.

Human activity is causing pollution in our air quality which affect animals, our environment and our health. Alternatives are on the rise to help decrease pollutants in our air which otherwise would increase environmental issues and our health. There maybe some obstacles in changing over how we produce energy but the benefits are worth the challenge in getting more people involved in using alternative resources.. = gases & particulate material added to the atmosphere. Can affect climate or harm people. Air pollution. = the release of pollutants. Outdoor (ambient) air pollution. = pollution outside.
