The Effects of Smog on Our Ecosystem |
|
|
|
 |
|
|
* The most obvious effect is the murkiness of the air, which smog produces. The median particle size in photochemical smog is so small that the particles preferentially scatter blue light, and depending upon the nature and angle of illumination, the air may appear blue or brown. |
|
|
|
|
|
|
* Another annoying feature of photochemical smog is the eye irritation and lacrimation it produces. One of the main eye irritants is peroxybenzoyl nitrate (PAN). |
|
|
|
* Lungs are smog's primary target. Smog damages lung tissue, causing inflammation and swelling. It also reduces the respiratory system�s ability to fight infection and remove foreign particles. |
|
|
|
* Various carcinogens, such as 3,4-benzpyrene, have been isolated from Los Angeles smog. These carcinogens mainly cause the skin cancer. |
|
|
|
|
|
* Photochemical smog produces an unusual type of plant damage called phytotoxic effect. It has been described as silvering, bronzing, or glazing, and usually first appears on the underside of the leaves. This type of damage has resulted in serious economical loss, the extent of damage varying markedly with the type of plant. It is not limited to agricultural crops. For example, spinach is especially susceptible. |
