[ Focus on Chemical Machinery and Equipment Network ] Ozone pollution has become the primary pollutant affecting the number of fine days in summer
.
Volatile organic compounds are important precursors for the formation of ozone pollution.
To achieve ozone peak reduction, it is necessary to strengthen the control of volatile organic compounds emissions
.

Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipment

In order to actively respond to the heavy ozone pollution in summer and monitor and find the source of air pollution in real time, our province has used navigating vehicles to pass VOCs (volatile organic compounds) navigation inspections in this year’s summer ozone pollution control battle, and classify volatile organic compounds emissions.
Carry out precise traceability to provide scientific and technological support for the precise control of ozone pollution
.

Some environmental protection experts said that the ozone-exceeding period is generally concentrated in the afternoon when the temperature is higher and the sun is strong.
Compared with PM2.
5 pollution, ozone pollution is more insidious
.
For example, it can irritate human eyes and damage human respiratory tract
.

On May 13, 2021, the Provincial Department of Ecology and Environment issued the "Notice on Carrying out the Navigation Inspection of Volatile Organic Compounds in 2021", and selected 5 navigation technology units with advanced domestic monitoring technology and equipment through public bidding.
Carry out navigation inspections throughout the province, give full play to the technical advantages of "fast, sensitive and accurate" navigation inspections, and accurately assist local governments in the coordinated control of PM2.
5 and ozone pollution
.

The voyage inspection covers 11 districts and cities across the province.
In addition to volatile organic compounds (VOCs), the monitoring factors also cover six indicators of air quality standards, namely sulfur dioxide (SO2), nitrogen dioxide (NO2), particulate matter ( PM10, PM2.
5), ozone (O3) and carbon monoxide (CO) provide various support for coordinated air quality management and control
.

As of June 20, the province’s technical units had travelled 108 days and 10,394 kilometers, inspected 439 business units (including catering), 226 gas stations and 4 oil storage depots, and found 447 problem points
.
Among them, there are 157 VOCs related problem points, 110 industrial enterprises, 36 gas stations, 11 social sources (including road marking, public facilities painting and other municipal construction and dry cleaning shops, etc.
); particulate matter related problem points 112 There are 18 industrial enterprises involved, 19 construction sites, 65 road dust, and 10 others; 106 NO2 related problem points, 2 industrial companies involved, 103 traffic sections, and the other 1; SO2 related problem points 30; 44 CO-related problem points
.

At the same time, in order to effectively play the role of navigation inspections, the Provincial Department of Eco-Environment has established a linkage mechanism between navigation inspections and ecological environment law enforcement and a closed-loop working mechanism of "discovering problems during inspections, transferring to the office for rectification, tracking inspection and supervision, and checking and evaluating numbers
.
" As of June 20, the province has transferred a total of 312 outstanding problem points, of which 223 have been completed
.

According to statistics, from May 1 to June 20, the proportion of good days in our province was 63.
1%, an increase of 2.
3 percentage points year-on-year
.
Ozone exceeded the standard for 166 days, a decrease of 32 days compared with the same period last year
.
