The Relationship Between Free Radical Reactions and Environmental Factors in High Altitude Area
高原环境因素与自由基反应

High altitude area is a special eco-environmental system. The complex and changeful geographical conditions in high altitude area make the new migrations of human or animals affected by Mountain Sickness. The oxidative stress reaction induced by low of atmospheric and oxygen pressure and strong sun radiation is one of main causes of Mountain Sickness. In this paper, the relationships between different environmental factors in high altitude area and free radical reactions has been discussed in 6 areas. First, the results show that free radical reaction have significant negative relationship with atmospheric air pressure and oxygen pressure. Second, the native people in plateau can also be affected by free radical reaction as well as the new comer. Third, the native people in plateau can get an inherit adaptability. Forth, the inner nutrition materials can resist free radical reaction. Fifth, people exposure to high UV radiation would be easily affected by free radical reaction. Sixth, Low selenium and iodine in environment is also risk factors for people affected by free radical reaction. This study is not only of an important significance in understanding the free radical reactions induced by environment stress as well as the origin and evolution of native people, but also is practically valuable for studying the Mountain Sickness of crowds immigrating to high altitude areas as well as the sickness prevention and treatment. In addition, this study is valuable for the economic development and national defense construction in high altitude area. This study may provide valuable references for studying the regulatory effects of environmental factors on Mountain Sickness and their physiology in the Western Development of China.
