Problems solved by technology

Under normal temperature and pressure, the stability is poor, and it can be decomposed into oxygen by itself
Although ozone plays an important role in protecting humans and the environment in the stratosphere, it can have harmful effects on human health if its concentration in the troposphere increases

Embodiment Construction

[0027] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0028] 1 Materials and methods

[0029] 1.1 Data source

[0030] The concentration data of ozone and nitrogen oxides come from the monitoring data from 2015 to 2018 of the 2 ambient air quality automatic monitoring stations of the Shihezi City Environmental Monitoring Station. The 2 automatic monitoring stations are respectively distributed in the old city and the development zone of Shihezi City. Among them, the monitoring stations of Ai Qing Poetry Museum are distributed in the old city, and the Sunshine School is distributed in the development zone. According to the requirements in "Air Quality Standard" (GB3095-2012) and "Ambient Air Quality Index (AQI) Technical Regulations" (HJ 633-2012), the O mentioned in the present invention 3 The concentration is the maximum 8h moving average maximum value, and the city-w...

Abstract

The invention discloses a method for researching relationship between excessive ozone and nitrogen dioxide in summer. According to the method, air quality data monitored by a Shihezi city environmentmonitoring station is utilized to carry out statistical analysis on the days that ozone appearing in the stone city is a primary pollutant, especially ozone exceeds the standard, the relationship between nitric oxide and ozone concentration is sought, and finally the relationship between the NO2 concentration of the stone city and ozone pollutants is obtained. The conclusion shows that when ozoneexceeds the standard in summer, the concentration of O3 is increased by about 14 hours later than the concentration of NO2, and meanwhile, the concentration of NO2 has a certain effect on formation ofO3.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a research method for the relationship between ozone exceeding the standard and nitrogen dioxide in summer, in particular to a research method for the relationship between ozone exceeding the standard and nitrogen dioxide in Shihezi City in summer. Background technique [0002] Since 2015, 337 cities above the prefecture level in China have carried out fine particulate matter (PM 2.5 ), ozone (O 3 ) six-parameter air quality monitoring, the monitoring results of the past four years show that in addition to some cities in winter PM2. 3 According to statistics from the China National Environmental Monitoring Station, there were 132 cities with excessive ozone in summer in my country in 2018, accounting for 39.2% of the 337 cities in the country. It can be seen that the ozone pollution in summer in my country is particularly prominent. [0003] Ozone (...
