Haze — The Constant Struggle with Invisible Pollution
SHANGHAI, March 12, 2015 /PRNewswire/ — During the National People’s Congress and the Chinese People’s Political Consultative Conference, a self-financed documentary film made by Ms Chai Jing, former anchor of China Central Television about China’s haze unexpectedly drew the attention of the media. Within 24 hours, it boasted over 6 million hits and over 60 thousand "likes".
What is Haze? Where does it come from? What can we do about it? To try to answer these questions, the film inevitably mentions the fact that in January 2013, 25 provinces which account for half of Chinese population were trapped in a severe haze. Though things improved in 2014, many big cities still have serious haze. In 2014, 175 days of Beijing, 197 days of Tianjin, 152 days of Shen Yang, 125 days of Chengdu, 112 days of Lanzhou and even 264 days of Shi Jia Zhuang were severely polluted by haze.
What is Haze? What harm does it do to human bodies? Haze contains sulphate, nitrate, ammonium salt, organic substances, minerals,etc. which collide, set off chemical reactions and harm the respiratory system, cardiovascular system and even cause early deaths.
In areas where haze is severe, many non-smokers suffer from lung cancer. Even newborn babies have gotten pneumonia of an unknown origin. In the past 30 years, lung cancer mortality has soared 465%. Mr. Chen Zhu Lan, former Minister of Health pointed out that every year that about 500,000 people die earlier because of haze.
Where does Haze come from? Burning of coal, oil, biomasses, industrial production, cultivation, etc. cause haze. And, 60% of all the burning has to do with production and daily habits.
What can we do about haze? We should clean the coal beforehand, control emissions, reduce pollution, use public transportation, save on energy, etc. According to Mr. Lu, Yao Ru, an academician of the Chinese Academy of Engineering, plants and water can treat it.
The International Rooftop Landscaping Association (IRLA) has committed itself to the study of how to help purify the atmosphere by introducing roof and wall greening in most Chinese cities.
IRLA will cooperate with the organizer of the 17th Hortiflorexpo IPM Shanghai, Asian Largest trade show in floricultural, horticultural and garden industry to present a special forum about it during April 22-24, 2015 at Shanghai New International Exhibition Center (INTEX Shanghai., Ltd.).
