Japanese residents in Beijing are gravely concerned about the impact of serious air pollution by microparticle PM2.5, which measured more than nine times the upper limit of Japanese guidelines on Thursday.
Smog in the Chinese capital reached the highest point on the six-level scale of air pollution. According to data by the U.S. embassy, the atmospheric level of PM2.5, or particulate matter up to 2.5 micrometers in size, temporarily came to 671 micrograms per cubic meter.
The level compares with the upper limit of 70 micrograms, which would prompt the Japanese Environment Ministry to call for caution.
