What is the contribution rate of Wuhan PM2.5 sources?

The reporter learned from the Wuhan Municipal Environmental Protection Bureau that the three major sources affecting Wuhan’s air quality are industrial emissions, motor vehicle exhaust emissions and urban dust pollution.

Among them, industrial sources rank first in contribution rate to Wuhan’s PM2.5.

Preliminary research results on source analysis of the causes of haze in Wuhan show that external source pollution accounts for about 20-30% of Wuhan’s haze.

Endogenous pollutants are the main cause. The three main sources are industrial emissions, motor vehicle exhaust emissions and urban dust pollution.

Among them, the contribution rate of industrial sources to PM2.5 in Wuhan ranks first, accounting for about 40%, the contribution rate of dust is about 25%, and the contribution rate of motor vehicle exhaust emissions Accounting for about 20%, the rest is from domestic sources and rural areas.

The "Urban Environmental Air Quality Compliance Plan" and the "Wuhan City Action Plan for Improving Air Quality" compiled by Wuhan City clearly define the phased goals and tasks for improving air quality.

The overall goal is: after five years of hard work, the city's air quality will generally improve, and heavily polluted weather will be significantly reduced; it will take another five years to basically eliminate heavily polluted weather, and the city's air quality will be significantly improved.

Specific indicators: By 2017, the average annual concentration of inhalable particulate matter (PM10) in the city's air will decrease by 20% compared with 2012, and the average annual concentration of fine particulate matter (PM2.5) will decrease by 20% compared with 2013. , the number of days with good air quality generally shows an increasing trend year by year.

Focusing on the "Haze Control Plan", Wuhan City will focus on the following three tasks: first, accelerating the adjustment of energy structure, second, accelerating the adjustment of industrial structure and layout, and third, vigorously reducing air pollutants Emissions, control industrial pollution, control motor vehicle pollution, reduce dust pollution, and reduce pollution emissions from catering fumes and waste incineration.
