Environmental Science 1021F/G Chapter Notes - Chapter 21: Indoor Air Quality, Tropospheric Ozone, Nitric Oxide
Document Summary
Asthma: a chronic inflammatory respiratory disorder characterized by attacks during which the airways narrow, making it hard to breathe; can be fatal. Nitrogen dioxide is known the irritate lung tissue. Nitric oxide is a chemical marker for airway inflammation a telltale symptom of asthma. Air pollution plays an important role in the increasing numbers of asthma patients. Air pollution: any material added to the atmosphere (naturally or by humans) that harms living organisms, affects the climate, or impacts structures. Outdoor air pollution has been under examination for many years. Temperature inversion: a situation that occurs when the temperature is higher in the upper regions of the atmosphere than in the lower, causing pollutants to become trapped near earth"s surface spike in lower atmosphere sulphur levels. Much of the air pollution comes from vehicle exhaust and industry emissions emissions from coal power plants. Indoor air pollution from small particles released through solid fuels such as charcoal, wood or animal waste.
