Sysinno Encyclopedia - PM2.5, The Tiny Killers in Air


In air quality monitoring, PM2.5 is an indispensable indicator. While many have heard of PM2.5, what exactly is it? So, through this animated video, we aim to provide a clear and easy-to-understand explanation, allowing everyone to have a deeper understanding of PM2.5.


In this video, we will introduce you to:


**Comparison of Different Particulate Matter Sizes**


Particulate matter comes from various sources and is categorized based on its diameter. Compared to other particulate matter, PM2.5 has an extremely small diameter. This means that they can remain suspended in the air for longer periods and can easily penetrate our respiratory system.


**Impact of PM2.5 on Human Health**


The tiny size of PM2.5 particles allows them to penetrate deep into our lungs, causing severe harm to our respiratory system. Prolonged exposure to high concentrations of PM2.5 can lead to respiratory diseases, heart problems, and even cancer. This risk is particularly significant for the elderly, children, and individuals with respiratory conditions.


**Where Do Particulate Matters Come From?**


The sources of particulate matter are complex, including industrial emissions, transportation, agricultural activities, construction projects, and natural sources such as dust storms. Understanding these sources enables us to take better measures to reduce PM2.5 emissions, thereby improving air quality.


**Primary and Secondary of PM2.5**


PM2.5 is classified into primary and secondary categories. Primary PM2.5 refers to particles directly emitted into the atmosphere, while secondary PM2.5 refers to particles generated through chemical reactions of gases in the atmosphere. Understanding the differences between these two types helps us predict the changes and sources of PM2.5 more effectively.


Through this article, we hope readers can gain a deeper understanding of PM2.5 and recognize the collective effort needed to improve air quality, safeguarding our health and the environment. Stay tuned as we continue to bring you more knowledge about environmental protection and health awareness!"
