" Pearl trigonometry gray haze weather is reduced by half

" Pearl trigonometry gray haze weather is reduced by half and still needed more than ten years " Gray haze monitoring net has been already built up
The meteorological expert Deng XueJiao claims that reducing gray haze needs implementing " Three runs on foot " Strategy

It is reported ' Little and intelligent Tang, intern of madder, Liu, reporter of South Daily,) Gray haze weather is perplexing every city of the pearl trigonometry for a long time. Gray haze days when make the pearl triangular are reduced by half, it takes several decades at least. Yesterday, Assistant Researcher Deng XueJiao of the tropical marine research institute in Guangzhou of China Meteorological Administration told reporters.


Deng XueJiao says, mainly there is a reason of two respects in the production of the gray haze, one is discharge of the pollutant, another one is the activity of the meteorological factor.


She says, if you want to make the gray haze days of pearl trigonometry reduced by half, takes several decades at least, and need to reduce gray haze " Three runs on foot " Strategy. The first step is set up the monitoring system of disposal of pollutants. Second set up prewarning of meteorological observation and monitoring, predict the system. Third want, set up gray haze monitoring system that area link, set up the monitoring station in the triangular all parts of pearl, whole area form one network of intercommunication, take place behind the gray haze, monitoring system soon can find out from which district causes, thus contain the production of the gray haze from source. It is reported, the gray haze monitoring net of triangular area of pearl has been already built up, the main website has been set up in Fanyu, the 8 sons station in all, 4 among them are set up in Guangzhou.


Chief and assistant Dr. Tan HaoBo says on the tropical ocean of Guangzhou of China Meteorological Administration, on the occasion of the serious period of gray haze weather in Guangdong during the Asian Games, in order to guarantee the air quality of the Asian Games, can draw lessons from the method of Beijing Olympic Games, adjust and control the discharge of the perimeter industry pollutant of venues, but the focal point is to reduce the emissions of pollutant from industrial enterprise of wind district on the court.

The total annual mean value of sulfur dioxide lowered twenty percent than the year before last last year


It is reported ' Reporter's old real horse is strong) Yesterday, the HKSAR government environmental protection administration has released the regional air of Pearl River Delta of Guangdong and Hongkong and controlled the monitoring result report in 2008 of network with the environmental protection agency of Guangdong Province together. Compared with 2007, in 2008, air quality will be improved to some extent generally in the district. The total annual mean value of sulfur dioxide and inhalable particles drops by 19% and 11% compared with the same period of last year separately; The density of NO2 and ozone roughly keeps steady.


Report,unless 2008, pearl pollutant is getting lower relatively in density summer such as trigonometry,and winter (such as from January to March and 10 to December) The density of the pollutant is relatively high. The expert analyzes, this and situation of in the past is roughly similar. The reason is roughly because there is more and mixing the layer general rainwater relatively tallly in pearl trigonometry summer, favorable to the diffusion of the pollutant.


The environmental protection department is making the triangular area of pearl to unite and accuse of planning

Tension army reveal environmental protection portion organize expert recently, carry on key the intersection of air pollution and area divide according to atmospheric circulation and the intersection of transport and situation of pollutant, according to these division, environmental protection department confirms key area of next prevention and control of air pollution as the pearl trigonometry, long trigonometry and Beijing, Tianjin and Hebei area tentatively.


Tension army claim environmental protection portion make, unite and accuse of planning in order to solve the triangular pollution problem of pearl by one the intersection of pearl and triangular area.
