澳洲论文没过:资源污染带来的负面影响

水污染和土壤污染是主要问题,但没有什么比空气污染更能代表这个国家的生态退化。因此,由于资源污染,在短期内,北京将经历水和食物的短缺。从长远来看,有毒的空气将增加由污染引起的疾病的数量,这些疾病将进一步导致生活在北京的人死亡。根据伯克利地球研究中心的一项研究,中国每年有近160万人死于空气污染。此外,没有人比儿童更容易受到空气污染的有害影响(Wu等,78)。儿童将特别受到若干方面的影响,患呼吸道疾病和哮喘的儿童人数将特别增加。未来,这种不断增加的污染将导致神经认知或发育延迟,与暴露于污染有关。我国政府的主要目标应该是减少氨氮、氮氧化物和硫氧化物的排放。此外,重点是测量水中的有机污染物,即化学需氧量(COD)。中国政府的主要目标应该是将二氧化硫排放量减少15%,COD排放量减少10.1%。
中国应承诺采取一项代价更高的举措,关闭一半的燃煤电厂,同时必须考虑用更清洁的发电技术取代燃煤电厂,这种发电技术的关键可靠性在于可再生能源、核能和天然气作为燃料。为了使北京的空气质量达到健康水平,中国将不得不考虑取代燃煤发电的大量价值,尤其是在污染严重的地区或附近。替换的一半的煤炭发电解雇了在北京核能和可再生能源,将每年花费近1840亿美元(Wang和Jiming, 2)。然而,针对表现最差的煤炭发电厂的电力可能导致减少二氧化硫和颗粒物的排放总量在全国超过25%。未来,政府可以考虑加快丢弃所有高污染卡车和汽车的速度。中国政府已开始朝着这个方向努力,但有必要加快速度。但是,目前有1 400多万辆汽车有或没有基本的污染控制设备。在2009年消除这些车辆可能有助于消除北京70%的挥发性碳氢化合物和一氧化碳,61%的氮氧化物,以及近76%的特定物质的排放。

Contamination of water and soil are major issues, but nothing can be symbolized with the ecological degradation of the country than air pollution. Thus, as a result of resource contamination, in the shorter run, Beijing will experience shortage of water and food. In the longer run, the toxic air will increase the number of pollution borne diseases that will further result in the death of people living in Beijing. According to a research by Berkeley Earth, it had been concluded that air pollution kills almost 1.6 million people across China every year. Also no one can be seen as more susceptible with harmful impacts of air pollution in comparison with children (Wu et al. 78). Children will be affected in a number of ways specifically, with specifically increased number of children suffering from respiratory illnesses and asthma. Further ahead, such increased pollution will result in neurocognitive or developmental delays in link to be exposed to pollution. The key aim of the government of China should be focused on cutting the emissions of ammonia nitrogen, nitrogen oxide and Sulphur oxide. Also the key focus is on measuring organic pollutants in water, namely, chemical oxygen demand (COD). The key objective of the government of China should be focused on reducing the discharge of Sulphur dioxide by 15 per cent and discharge of COD by 10.1 percent.
China should show commitment to a more expensive initiative to shut down half of the power plants fuelled by coal, and there must be a consideration to replace them with cleaner technologies of generating electricity with key reliability on renewable, nuclear and natural gas for fuel. For reaching healthy levels of air quality in Beijing, China will have to consider replacing a substantial value of electric power fired by coal, specifically near or in major centers of pollution. By the replacement of half of the electric power generation fired by coal in Beijing with nuclear power or renewable, will be costing almost 184 billion dollars every year (Wang and Jiming, 2). However, targeting the worst performing power plants fired by coal could result in reducing the total emissions of sulphur dioxide and particulates across the nation by more than 25 per cent. Further ahead, the government can consider accelerating the speed of discarding all highly polluting trucks and cars. Beijing has started to move in the direction but there is a need to accelerate the speed. However, currently there are more than 14 million vehicles having rudimentary equipment of pollution control or not any. The elimination of these vehicles in the year 2009 might have helped in eliminating 70 per cent of volatile hydrocarbons and carbon monoxide, 61 per cent of nitrogen oxides, and almost 76 per cent of the emissions of particular matter by automobiles in Beijing.
