On the afternoon of August 21, the neighborhood stage on the 2nd floor, 259-1 Pushan Road, Jing 'an District, Shanghai was packed,"Be vigilant! Indoor air pollution is quietly polluting your home-digital monitoring, intellectual health science popularization series activities" Completing here.

This event was guided by the Shanghai Jing'an District Science and Technology Association and hosted by the Shanghai Indoor Environment Purification Industry Association. It attracted many residents who are concerned about home health. Through digital monitoring technology and expert interpretation, everyone has an understanding of "invisible air pollution". Have a new understanding.

Let invisible pollution "show"

"Talking with data is reliable!"An old man who had just finished decorating his new house carefully recorded the testing method. "Before, I always felt that ventilation would be safe for half a year. Today, I learned that the formaldehyde release cycle is as long as 3-15 years and must be monitored with professional equipment."

Shi Xing, founder of Lingze Technology, brought popular science content of "Digital Monitoring and Air Pollution Behavior Characteristics" to residents,from accurately quantifying air quality,The influence of temperature on the index,Contamination behavior identification and traceabilitygovernance effectiveness assessment,Live Experienceand so on many aspects of science. Let the residents really feel the use of air data to speculate the behavior of the people in the room, the residents at the scene called "amazing".

Cracking the "air myth" in life"

"If you have more than a dozen pots of green dill in your home, can you remove formaldehyde?" "It must be better to buy an expensive air purifier?" In the face of the daily confusion raised by the residents, the on-site expert team gave practical answers one by one.

Zhong Yilin, Senior Engineer, Shanghai Institute of Metrology and Testing TechnologyThe problem of "rapid detector" has been exposed: "The error of a detector with a few hundred yuan on the market may exceed 50%, and only a third-party test with CMA certification is reliable."Shi Xing, founder of Lingze Technology, explained through case studies how to trace the source of pollution through monitoring data.-"For example, kitchen fumes not only contain PM2.5, but also produce carcinogens such as benzopyrene. After cooking, the range hood must be continuously turned on for 20 minutes.

Li Rui, consultant of Hope Tree Environmental Protection Technology, Gu Jiajun, director of Lanshen Environmental Testing Technology, and Wei Chao, head of Youlan Technology Brand, also explained the "post-decoration treatment steps", "what do you think of the testing report" and "three elements of air purifier purchase (CADR value, CCM value and energy efficiency grade)" respectively. The full sharing of dry goods made residents take out mobile phone photo records one after another.

From "Blind Response" to "Scientific Protection"

"My child always coughs, is it related to dust mites in the bedroom?" "After the renovation of the old house, what should I do if the furniture smell doesn't go away?" In the interactive session, residents scrambled to ask questions, and experts gave targeted suggestions based on specific scenarios.

After the event, many residents are still around the expert consultation details."I used to think that no smell is no pollution, but today I know that odorless gases such as radon and carbon monoxide are more dangerous."An aunt took the activity manual and said, "When you go back, according to the experts, check the ventilation first, and then ask the professional organization to check it. Be steadfast!"

DepartmentColumnActivities will continue

Guard respiratory health

As an important stop of the series of popular science activities of "paying attention to air pollution and guarding respiratory health", this activity makes more people realize:Indoor air safety needs "data management". The organizer stated that in the future, it will continue to enter more communities, schools and parks to help citizens establish a scientific awareness of protection through popular science lectures and free testing experiences.

Air is the source of life, breathing more than 20000 times a day "invisible companion", more need us to guard attentively. The next popular science activity is about to start, making the air safer and life healthier!
