become the first hot search

according to japanese media reports on october 1, since december last year, water quality surveys in higashihiroshima city, hiroshima prefecture, japan have shown that many water bodies near the local us military ammunition depot are seriously polluted, and one of the groundwater contains per- and polyfluoroalkyl substances. the content exceeded the standard by 300 times.

after repeatedly denying it, the us military stationed there changed its story in september and admitted to using foam fire extinguishing agents containing per- and polyfluoroalkyl substances for 19 years.

on september 30, the higashihiroshima city government requested an investigation into the us military base and publish the results.

per- and polyfluoroalkyl substances are difficult to degrade and accumulate in the environment and human body. they are called "forever chemicals". since last year, it has been exposed in many places in japan that the content of per- and polyfluoroalkyl substances in water bodies exceeds the standard, and nearby residents have abnormal blood tests. since most of the incident areas are close to us military bases in japan and japanese self-defense force bases, these bases are regarded as possible sources of pollution.
