Japan: Kumamoto Issues Air Pollution Warning caused by PM2.5

The Kumamoto prefectural government has become Japan’s first municipality to issue a warning over air pollution caused by PM2.5 under provisional state guidelines introduced last week.

The Kumamoto government issued a warning Tuesday on its Web site and by e-mail after the daily average level of PM2.5, or particulate matter up to 2.5 micrometers in size, was forecast to exceed 70 micrograms per cubic meter of air.

At 5 a.m. (8 p.m. Monday GMT), the level reached 91 micrograms per cubic meter of air at Kumamoto’s Arao government building. The level was 90 micrograms at 6 a.m. and 101 micrograms at 7 a.m.
