Health newspaper: Should not study ostriches to the crisis
Wu LanYou ( Staff member) November 19, whom Zhong Shan City hold on the sixth healthy developing the intersection of Zhongshan and forum and at the Wu Jieping's medical award award-giving meeting 2011 year in Guangdong, academician Zhong NanShan shows, atmosphere and indoor air are what the people are depended on for existence while publishing the award-winning comment, particularly important to people's health, he appeals for announcing PM2.5 value, supervising the government department to manage gray haze together, improve the happy index of the people's lives. (" South Daily " of November 20) What is meant by PM2.5? PM2.5 means the diameter is less than or equal to particulate matter of 2.5 microns, have important influence on air quality and visibility,etc. in the atmosphere. The environmental monitoring of city of our country, PM2.5 value does not include in and monitor indication range, that have not announced the relevant index at least, this is environmental states and the important reasons the monitoring index which the department in environment protecting mode announces disagrees that the public experiences. For example, a scientific research institution has reached 130 monitoring Guangzhou PM2.5 value recently, have exceeded 13 times of World Health Organization's safety standard, but in the same period the department in environment protecting mode announces the data reveal the air quality in Guangzhou is " Good" . Because it is small can enter the alveolus to even ooze into the blood directly, initiates and includes various diseases such as heart disease, arteriosclerosis, lung sclerosis, lung cancer, asthma on PM2.5 particle. According to the report of " Beijing Times " on November 18, in the past 10 years, the morbidity of lung cancer in Beijing increases and is close to 60%, lung cancer has already become the citizens of Beijing " Killer of the first " . The relevant personnel analyzes that is thought, more than 90% of the lung cancer and smoking or smoking the second hand cigarette voluntarily and is closely related with, I think conclusion this it establishes to be must the past 10 years the whole society smoke quantity should promote obviously, the fact is not so say like this more possible reason is the serious air pollution. But the air pollution issue including PM2.5 value, in recent years no matter relevant policies and standard formulation, the air monitors the announcement of the index, the related departments have been avoiding to some extent all the time. In fact, PM2.5 data do not have technical difficult problem to monitor the reason lacked, it is quite cheap to monitor the cost too, the real reason is that the relevant organization has thinking of ostrich in the face of the pollution crisis, because once PM2.5 data disclose the air quality data and must be reduced. 2009, in environment protecting mode department pilot project monitor to gray day such as haze once, result reveal number that gray haze take place account for the days monitored and was up to 14.0% to 57.8% unexpectedly, among them 134 days, 211 days for 115 days of Shenzhen, Nanjing of Shanghai. On November 14, the official side of government of Nanjing is so a little rich as to reload onto the official side of weather bureau of Nanjing a little rich " density of PM2.5 slight particulate matter " that reveals Number value, deposit hour such as residual by " send by mistake " only In order to be deleted. Recently, the department in environment protecting mode has released " determination weight law of surrounding air PM10 and PM2.5 ", the determination that the diameter is no more than particulate matter PM2.5 of 2.5 microns has been standardized to suspending in the air for the first time. The issue of PM2.5 national standard means the distance PM2.5 enters nearly a steps even more of quality criteria of air finally, but this time is finally too long to have and clear more, the insider reveals and says " the new standard intends to implement in an all-round way in 2016 " . However, apply a popular word mechanically to say, " you examine the accident, PM2.5 is just there, do not reduce without increasing " ,Announce true environmental monitoring data go bankrupt, can let more person pay attention to and support the behavior in environment protecting mode while being opposite.
