In order to explore and solve the bottleneck problem of near-ground ozone pollution

by combing the ozone concentration data in Chaisang District and conducting ozone pollution analysis

it was found that meteorological conditions

local pollution and external transmission all had a greater impact on the change of ozone concentration to varying degrees.From May to September

the ozone pollution is relatively concentrated. The changes of ozone concentration are high during the day and low at night. From 12:00 to 18:00 in the day

the ozone concentration is relatively high

and it is affected by the emission of ozone precursors in the local atmosphere. It is necessary to strengthen the coordinated control of O

3

and PM

2.5

explore the source

and cause analysis of ozone pollution

and actively respond to ozone pollution through joint prevention and control

early warning and forecasting

publicity and guidance

and continuously improve and improve ambient air quality.
