TOKYO, Apr 25 (News On Japan) –
Organic fluorine compounds often called PFAS—suspected to be dangerous to human well being—have been detected at concentrations exceeding the nationwide provisional goal in rivers and groundwater at 242 websites throughout 22 prefectures, in response to a authorities survey.
Among PFAS substances, two compounds specifically—PFOA and PFOS—are thought of hazardous. Japan’s Ministry of the Environment has set a provisional goal of not more than 50 nanograms per liter for the mixed focus of those two chemical compounds in rivers and groundwater.
The ministry’s fiscal 2023 survey, which examined 2,078 websites in 39 prefectures, revealed that 242 websites in 22 prefectures surpassed the federal government’s goal for PFOA and PFOS concentrations.
The highest stage was present in groundwater in Settsu City, Osaka Prefecture, measuring 26,000 nanograms per liter—520 occasions the nationwide goal.
The ministry has urged native authorities to make sure that water from these websites will not be used for consuming functions.
