The SO2 Solution: Causes And Consequences Of Air Pollution
Introduction
The atmosphere is considered as a great cover that guards the earth’s surface from the full solar radiations during daytime and prevents excessive losses of heat during nighttime. The atmosphere provides a sustaining livable temperature on the planet by maintaining the heat balance of the earth. However, humans disregard the atmosphere through activities that contribute in polluting the surrounding. In order to prevent and minimize the air pollution, it is essential to understand the problems and be involved in problems resolution. [*]
Air pollution is considered as one of the world’s major killers according to WHO 2006. [**] It leads to early death of about 7 millions people yearly due to heart and respiratory system diseases …show more content…
The Figure below illustrates the annual SO2 emissions for Asia, Africa, Europe, and South and North America regions extending from 1850 to 2010. As a result of the developed industrialization energy demand, the SO2 emissions in Northern America, Europe, and Southern America peaked in 1970, 1980, and 1990 respectively. As for Asia and Africa, the increase in SO2 releases was delayed until the 20th century. Despite the noticeable increase in the SO2 emissions throughout the 20th century for Asia and Africa, it is still small relative to Europe and North America with a percentage of 30-50%. …show more content…
When the plants are being contacted to high concentration of SO2 around 1850 μg/m3 for short period of time that is about 1 hour, they got injured and the tissues died between the leaves margins and vines as Figure 4 illustrates. On the other hand, when the plants are exposed to SO2 for long time periods at low concentration of SO2 that reaches 40 μg/m3 the leafs color changed to brownish red and in some cases white as shown in Figure 5. Besides, the sensitivity of plants to SO2 emissions becomes worst when combined with high relative humidity, intense light and moderate temperature. The plants susceptibility to SO2 presents highly in specific types of plants especially vegetables such as beans, spinach and lettuce, crops such as alfalfa and cotton, and trees like apple and mulberry trees [555]. In addition to the injuries that are caused to the plants and trees when exposed to wet and dry deposition, the impacts might extend to reach the forest ecosystem highly including the soil properties and the atmospheric conditions.
