Beijing PM 2.5 Data of Today and History | How to Protect Yourself

PM stands for particulate matter and PM 2.5 Air refers to pollution consisting of particles with diameters that are generally 2.5 micrometers and smaller. The fine particles can be inhaled into deep branches of human’s lung. Some particles, like dust, dirt, soot, and smoke, are large enough to be seen with your naked eye, but the PM 2.5 can only be detected by microscope. As one of the major analyzed factors for Air Quality, it is measured as the main index to define weather the air quality is good or bad. Beijing, the capital of China, used to be infamous for its high PM 2.5. To help you have a clearer understanding of its current PM 2.5 trend and its change, we analyzed over 10 academic papers related to Beijing air quality in the latest 5 years.

There are numerous mask brands and types over the market. For air protection and the health of our customers, we are in no way affiliated to any of the mask producers, but here we have our sincere suggestion on choosing a good mask: The most common and affordable mask are known as the 3M N95 masks( "N95" stands for the mask is able to filter out at least 95% of airborne particles, 29 RMB for 5 pcs), and it is good enough for most of the PM 2.5, but you can also purchase N99 for sensitive groups, which can filter over the 99% of airborne particles. It is foldable and you can always packing one with you for your trip to China. And if you forgot to take one, you can also get this mask from any convinience store in China such as 7-Eleven.

According to the historical PM 2.5 data in Beijing, the local emissions accounted for 2/3, mobile sources accounted for 45% of local emissions, and regional transmission accounted for 1/3, but the contribution of regional transmission on heavy pollution days was greater than 50%.

The results demonstrate that local emissions account for two thirds of the main sources of PM2.5 in Beijing, and regional transmission accounts for one third. Regional transmission contributes about 20 micrograms/cubic meters to the average PM2.5 concentration of 58 micrograms/cubic meters in 2017. With the increase of pollution level, the contribution of regional transmission increases, and the provincial transmission accounts for 55% - 75% of the polluted days. Depending on the characteristics of PM2.5 source in Beijing, the mobile source accounts for 45% of the total.
