Compared with the old national standard, the new national standard increases the PM2.5 and ozone 8-hour concentration limit monitoring indicators for fine particles. Among them, in the area of ​​the ambient air function zone, the annual average concentration of PM2.5 does not exceed 15 μg/m3, and the average concentration at 24 hours does not exceed 35 μg/m3.
The concentration of PM2.5 in residential areas closely related to public health, the new national standard provides that the average concentration of PM2.5 in residential areas should not exceed 35 micrograms/cubic meter, and the 24-hour average concentration should not exceed 75 micrograms/cubic meter. The relevant person in charge of the Guangdong Provincial Environmental Protection Agency stated that the PM2.5 standard is the same as the WHO's target period for the transition period.
Relevant air quality experts believe that the new national standard still has a low standard for PM2.5. According to the current strict international air quality guidelines, the average annual concentration of PM2.5 particles in healthy air should be less than 10 micrograms/cubic meter. Above this value, the total death rate in the population, the mortality rate of cardiopulmonary diseases and lung cancer Mortality will increase significantly.
Pearl River Delta Advances New National Standard
The “Ambient Air Quality Index Technical Regulations†was also implemented in parallel with the new standard, which also indicates that the current air pollution assessment index implemented in Guangdong will become an ambient air quality index. According to the Guangdong environmental protection department, AQI will be able to better characterize the current state of ambient air quality in the city, and in particular, reflect the current prominent compound air pollution problem in the PRD. At the same time, the new standard can, to a certain extent, eliminate the phenomenon that the subjective perception of the public and the results of monitoring and evaluation are not completely consistent.
