Hubei implementation of the air negative oxygen ion concentration standard after the rain there is a-e2140

Hubei implementation of the air negative oxygen ion concentration standard after the rain there are quantitative standards yesterday, Jiangcheng was shrouded in fog. Figure 27 Yangtze River bridge partly hidden and partly visible in the fog. Reporter Zhou Di photo newspaper (reporter correspondent correspondent Xia Fu Li Ao) after the rain, how fresh the air? In the future, there is a quantitative standard. According to Hubei Provincial Meteorological Bureau, province air negative oxygen ion concentration level of local standards implementing zuoqi. People in the Provincial Meteorological Bureau, the standard to reflect the average air condition, to determine the air concentration of negative oxygen ions is the best grade: Grade I, the concentration of negative oxygen ions per cubic centimeter of not less than 1500, the worst is V-grade, per cubic centimeter of negative oxygen ion concentration is less than 100. What is the use of negative oxygen ions? Meteorological science experts explained that the negative oxygen ions in the air is full of oxygen ion with negative charge, known as "air vitamin", in the air after the rain often filled with fresh taste, is due to the negative oxygen ion. According to WHO confirmed that the amount of negative oxygen ions in the air to reach 1000 cubic centimeters per cubic centimeter, is considered to be fresh air. Hubei is the earliest to carry out one of the air negative oxygen ion observation and application of the provinces, the province’s construction began in October 2013 of negative oxygen ions in the air station network, in March 2014 to provide real-time monitoring and service air concentration of negative oxygen ions. Later, the province also plans to gradually release the negative oxygen ion concentration monitoring data and related services to the public. The number of air negative oxygen ion concentration (N) unit (CM) rating 102100 = N 3500 = N 41000 = N 5 N = 1500 grade is suitable相关的主题文章:
