Document Summary
Air is composes the atmosphere and is a complex mixture of gases. The atmosphere is a layered structure divided into layers according to a variety of criteria such as gradual changing: Composition of air: mixture of several gases and ne particles/vapour, dry air consists of 21% oxygen and 78% nitrogen. When inhaled carbon monoxide binds to the oxygen-carrying site not the hemoglobin of red blood cells, causing a reduction of oxygen transport in the body, resulting in cell/tissue death. Ozone: naturally occurring gas that forms a protective layer in the atmosphere, predominantly present in the stratosphere (absorbs harmful ultraviolet radiation from the sun) Ground-level ozone is produced during photochemical reactions between volatile organic compounds (vocs) released in automobile exhaust and oxides of nitrogen in the presences of sunlight. Reaction between voc and nox in the presence of sunlight is called photochemical reaction. Can lead to damaged biological tissues/cells, lung function, itchy, burn and watery eyes.
