Introduction of Sulfur Dioxide Sulfur dioxide is a colorless gas which with a pungent odor. It will become liquid form when under pressure (heat) and will dissolves in water very fast or easily. The primary sources of sulfur dioxide are comes mainly from some activities such as burning of fossil fuel to provide electric power, process of making steel, coal-burning and others. However, it can also be released from the natural volcanic activity or volcanic eruption to the air. This gaseous can easily pose a threat to the living things such as human, animal and plant. Life Cycle MacLeod et al. (1961) was confirmed that when the entry rate is low, sulfur ion can enter the metabolic pathways of plants normally without any distinct injury or symptom on the leaves. However, if the amount of sulfur ions excess the ‘normal’ quantities in the plant requirement enters, it can affected the metabolism of plants or the characters of chronic injury (yellowing) to the plants will develop no matter how slowly the sulfur enter the plants. But when the sulfur enters the plants rapidly, the metabolic systems of plants for coping with sulfur will overwhelmed and it can causes the acute injury occurs (bifacial intercostals necrosis). Causes by the Sulfur Dioxide Sulfur may enter the plants in few ways such as enter through the roots in form of sulphate ion, dissolved in water with form of sulphate ion or in form of gaseous sulfur dioxide (SO2) which can penetrates into the leaves through the stomata. But both of it can be utilized by plants through the metabolism of normal sulfur, although the limited pathway via cuticle was proof. However, the aperture of the stomata was largely controlled by conditions of the environment, such as temperature, ligh... ... middle of paper ... ...ts. Because when the plant is in a good condition or health, it can resist all type of injury compare to weakened plants. To maintain the health of plants, we can water it in time of drought, fertilize it when needed and the soil should be in a good condition also. Such as well-draining, not compacted and must be porous. Secondly, we can try to choose the plant which is more tolerant to the air pollutant. Third way is try to reduce the emissions from the source if possible. Works Cited REFRENCE 1. Retrieve from: 2. Retrieve from: 3. Retrieve from: 4. Retrieve from: 5. Retrieve from:
