The importance of the environment to us is like the importance of water to fish, without a good environment we will not have a good body, we may suffer from a variety of diseases caused by bad environment. With the advancement of the industrial revolution, our environment is slowly deteriorating, PM2.5 is one of the major environmental problems that has been bothering people in recent years, and wherever it appears, it always has a bad effect in one way or another. From the beginning, we do not think, but later gradually pay attention to, our country has also taken a lot of effective measures, including the monitoring of PM2.5, this initiative has brought a lot of help to solve the PM2.5.

 

(I) The purpose of monitoring PM2.5

PM2.5 is a kind of particulate matter pollution that can cause harm to human respiratory system and cardiovascular system, when it reaches a certain concentration, it will greatly increase the probability of human illness, and even lead to babies born with birth defects, premature death and so on. Moreover, the Cancer Research Center has pointed out that PM2.5 can induce cancer, so it will cause a certain sense of fear to people’s psychology if it appears frequently, and will affect the stability of social order if it is serious.

 

If PM2.5 appears regularly, it will greatly reduce the visibility of the city, and even affect the overall image of the city, which is not conducive to the construction of the city. It is also a great threat to the environment, inhibiting to a certain extent the purpose of co-development of the city and the environment.

 

When the concentration of PM2.5 reaches a certain level, it will affect people’s vision and cause a lot of inconvenience when traveling, and in serious cases, it may even cause serious traffic accidents, which will cause certain losses to people’s lives and property safety.

 

(II) The significance of PM2.5 monitoring

As cities monitor PM2.5, people pay more attention to protective measures when traveling, and their environmental awareness is stronger, and their own daily behavior is improving. The degree of concern for suspended particulate matter (SPM) and respirable particulate matter (RPM) in the air has been greatly improved, which, to a certain extent, also promotes the national monitoring and resolution of PM2.5.

 

The most obvious change in the monitoring of PM2.5 is the change in the city, the number of occurrences and severity of PM2.5 is in a downward trend, and every day’s index will give people a new surprise and a sense of solidity. The overall image of the city has been well protected and improved, including, of course, people’s daily environmental behavior.

 

PM2.5 monitoring is also a spur to those backward and unqualified enterprises, promoting the adjustment and upgrading of industrial structure, and improving the improvement of people’s way of traveling.

 

Most of the PM2.5 sensor on the market now its basic principle is that the laser after scattering, the set of optical sensors above the output signal for further digital processing, and then measure its parameter settings, the results display, key, time, date, etc. are controlled by the built-in microcomputer, to achieve. The monitoring of PM2.5 is an important step in solving this problem, and it can be seen that it does play a good role. For people living in the city, have the responsibility and obligation to pay attention to and care about the specifics of PM2.5 monitoring to play a role in encouraging and spurring, but to really solve the PM2.5 words rely solely on monitoring is not enough, but also need to work together.
