Juan G. R., Juan G. R., Juan P. J. A. Level of air pollution in China.
Water and Irrigation Vol .: 7, No. 1: 11-12, May, 2016, Spain.
The level of pollution in many regions China has more than 400 micrograms per cubic meter of air values that greatly exceeds 25 micrograms per cubic meter recommended by the World Health Organization. When increase the amount of suspended particles in the air the risk of patients with respiratory problem, asthma, cardiovascular and cancer patients disease increase, each year die in China around 425,000 Chinese as a result of high environmental pollution , which indicate that humanity is advancing along an unsustainable path that threatens the destruction, but is necessary to counter the impact of human activity taken measures in time.
The northern area of China is the most affected by pollution and is represented by the cities of Beijing and Tianjin and the provinces of Hebei and Shanxi. In the Northeast zone the most damaged is Liaoning province, in the northwest pollution affects Shaanxi Province. There is a high level of pollution in Henan Province and the administrative region of Hong Kong as well as in the province of Shandong and Shanghai municipality located in the eastern region of the country. Pollution extends over an area that affects about 500 million people.
Major cities in China suffer one of the highest atmospheric pollution, water supply is also very polluted. The concentration of airborne particles, lower than 2.5 microns, the most dangerous to health for its ability to infiltrate the lungs, sometimes reached 700 micrograms per cubic meter in cities like Beijing and greatly exceeds the 25 micrograms per cubic meter recommended by the World Health Organization. Areas with more water pollution are the Yangtze River Delta which includes Shanghai and the Pearl Delta main manufacturing center of the country, home to Guangzhou and Shenzhen, according China sources of information.
China is the second largest economy in the world but is also the biggest polluter and energy consumer in the world, about 60% of the energy is obtained from coal and industries facilities do not have adequate filtering technologies. China has suffered many demonstrations and protests caused by the problems of environmental pollution, since a large number of cities have been affected by acid rain and one-sixth of its major rivers contain water that is unfit for human consumption or many crops. Faced with criticism of the population to the Chinese authorities for not taking the necessary measures to reduce pollution, the government reacted by shutting down industries and reducing emissions of polluting gases.
The Chinese government invests about 300,000 million to fight pollution control afflicting the country is overly dependent on coal the main source of energy. 37 percent of the investment is intended to improve air quality, 28% to the development of renewable energy sources and 35% .se dedicated to environmental policies, treatment of industrial waste and improved the quality of vehicle engines. To this extent the ban on new industrial projects in sectors like cement or steel adds, both highly polluting. It is considered that16 of the 20 most polluted cities in the world are in China. A study by the Chinese government showed that only 4% of 471 cities surveyed recorded an air with a maximum level of cleanliness.
The number of cars in China increased from 16 million in 2000 to currently around 100 million, which also contributes greatly to the carbon pollution. China’s economic level worldwide has increased much you but levels of environmental quality have greatly diminished due to accelerated industrial development, which has not had the resources and appropriate controls for environmental protection. High levels of air pollution and water, environmental lead pollution and loss of biodiversity and population growth are problems that the Chinese government has to assess to try to achieve sustainable development, better environmental quality and a better standard of living.
There are already many cities in the world with pollution levels above 200 micrograms per m3 air, China is at the forefront with having the most polluted cities, by increasing the amount of suspended particles in the air, the risk of patients increases with respiratory diseases, asthma, cardiovascular and cancer patients, each year die in China about 425,000 Chinese as a result of high environmental pollution, indicating that humanity is advancing along an unsustainable path that threatens the destruction, but is necessary to counter the impact of human activity taken measures in time.
