Before the International Clean Air & Blue Sky Day, the activity themed with “Visiting the laboratories, paying attention to the air and blue sky” was launched by Tiexinli Primary School in Haigang District, Qinhuangdao City and Qinhuangdao Ecological Environment Bureau.
Teachers and students went to the inorganic laboratory, organic laboratory, and large-scale instrument room in Qinhuangdao Environment Monitoring Center, learning knowledge about air sampling, experimental analysis, and safety, paying attention to air quality, and arousing awareness of environmental protection.
