On the afternoon of July 16, the first series of popular science activities with the theme of "paying attention to air pollution and protecting respiratory health" was held at the Party and Mass Service Center of Shimen second Road Street, Jing'an District, Shanghai. More than 50 residents from Shimen second Road Street, Jing'an District participated in the activity. This popular science activity is guided by the Shanghai Jing'an District Science and Technology Association, sponsored by the Shanghai Indoor Environment Purification Industry Association, and undertaken by the Shimen Second Road Street Science and Technology Association.

This popular science activity focuses on science and technology empowerment to make good air "visible". Formaldehyde, benzene, TVOC, haze, second-hand smoke, dust mites, soot, musty smell, odor, invisible, but affect people's respiratory health and quality of life, formaldehyde, PM2.5, CO2, TVOC is not exceeded, indoor temperature and humidity? Through sensor monitoring can grasp the air data, so that these air quality index can be "seen".

Popular science activities have received positive response and support from industry enterprises. Shanghai Lingze Information Technology Co., Ltd. provides on-line air quality monitoring equipment. Through experiments, residents can see changes in air quality data on their mobile phones on the spot, accurately monitor them, provide reliable data support for scientific governance, and change the judgment of air pollution by nose "sniffing" and "guessing". Shanghai Shiyi Brand Co., Ltd. provides a variety of air treatment products under the "Hope Tree" brand, and adopts different product solutions for different scenarios.

Zhong Yilin, the head of the two enterprises and the laboratory director of the Environmental Protection Station of the Shanghai Institute of Metrology, explained in plain language "why should we pay attention to indoor air pollution?

Residents enthusiastically interact with business representatives and experts to answer questions encountered in life. Resident representatives said that this popular science activity has learned a lot of knowledge, and will pay attention to indoor air pollution and other issues in future life, and learn to use scientific means to protect the respiratory health of themselves and their families.

According to the person in charge of the public welfare science popularization activities of the Shanghai Indoor Environment Purification Industry Association, the "Focus on Air Pollution and Protect Respiratory Health" series of science popularization activities will enter more communities, parks, schools and buildings in the next step, so that more citizens can improve their indoor environment.
