Organic fluorine compounds (PFAS) were detected near the Yodogawa Plant of major air conditioner manufacturer Daikin Industries (Settsu City, Osaka Prefecture). Kyoto University and the Osaka PFAS Pollution and Health Association, a citizen group, announced the blood test results on the 11th. A survey of Cook County residents has been released. Of the 1,190 people tested, 364, or 31%, exceeded guidance levels set by U.S. academic institutions that may increase health risks. (Tomoyuki Morimoto)
◆Some people’s “values are much higher than expected”
Although the main source of emissions appears to be the same factory, there are also people living in remote areas with higher emissions, posing a health risk. Harada Koji, associate professor at Kyoto University, said at a press conference in Osaka on the 11th, “The numbers are much higher than expected. Because PFAS is widely used, there are many cases of unknown origin, and if tested, it can be detected nationwide. .
Daikin’s Yodogawa plant began processing PFOA, a type of PFAS, in the late 1960s, but in 2012, all domestic plants, including the Yodogawa plant, stopped production and use. A Daikin spokesman said, “We will not comment on the test results because the tests were not conducted by our company and we are not aware of the details of the tests, including the analysis methods and accuracy.”

Get a blood test to check for the four main types, including PFOA and PFOS. The total value of seven types, including these four, was compared to the guideline value per milliliter set by the United States (20 nanograms = one part per billion of a nanometer).
◆Detection of PFOS that Daikin does not handle
Exceedings of the guidance were most common in the northern part of the county, where the factory is located, but measurements were also taken in the southern part of the county. Many people had high levels of PFOA but also detected PFOS, which Daikin does not treat. “Although there is a range, the health risks are more concerning than expected,” Harada said.
The average per person is 17.7 naik. The concentration of PFAS was as high as that detected in a well near a U.S. military base in the Tama district of Tokyo. The highest levels, about 610 nanograms, were found among former employees of the plant living in Hyogo Prefecture.
