Pm2.5 is a kind of particulate pollution that can cause harm to the human respiratory system and the cardiovascular system. When it reaches a certain concentration it can greatly increase the probability of human illness and even cause babies to be born with defects and die prematurely. The Cancer Research Centre has also stated that pm2.5 can cause cancer, so its frequent occurrence can cause a certain sense of fear in people's minds and, in serious cases, can affect the stability of social order.
Pm2.5, if present on a regular basis, can greatly reduce the visibility of the city and can even affect the overall image of the city to the detriment of its construction. It is also a great threat to the environment, and to some extent inhibits the aim of developing the city and the environment together.
When the concentration of pm2.5 reaches a certain level it can affect people's vision and cause a lot of inconvenience when travelling, and in serious cases it can even cause serious traffic accidents, causing certain losses to people's lives and property.
2. The significance of pm2.5 monitoring
As cities monitor pm2.5, people are paying more attention to protective measures when they travel and are more aware of environmental protection, and their own daily behaviour is improving. The level of concern for suspended particulate matter and respirable particulate matter in the air has been greatly increased, which to a certain extent also promotes the national monitoring and solution of pm2.5.
The most noticeable change in the city is the monitoring of pm2.5. The number and severity of pm2.5 is on the decline and every day the index gives a new surprise and a sense of reassurance. The overall image of the city is well protected and improved, including, of course, people's daily environmental behaviour.
The pm2.5 monitoring is also a spur to those enterprises that are lagging behind and not qualified, promoting the adjustment and upgrading of industrial structure and improving the way people travel.
