Tokyo, Dec 20 (IANS) — Japanese authorities inspected the US Yokota Air Base in western Tokyo following concerns about the potential overflow of water contaminated with Per- and Polyfluoroalkyl Substances (PFAS), also known as "forever chemicals, " local media reported on Friday.
Key Details:
The inspection occurred two months after the US military informed Japan of a chemical leak during a firefighting drill on the base.
Officials from Japan's defense, foreign, and environment ministries, alongside Tokyo's metropolitan government and local municipalities, inspected the firefighting training area suspected of being the source of the contamination.
Focus of Investigation:
Future plans include collecting water samples from the reservoir within the firefighting area for analysis.
Statements and Concerns:
Deputy Chief Cabinet Secretary Fumitoshi Sato addressed the inspection:
"This inspection was conducted in response to the fears and concerns harbored by local residents. We will continue to work with the US side on this matter."
Impact of PAFS:
PFAS, used in firefighting foams and various products, is known for its persistence in the environment, earning the nickname "forever chemicals."
The US military in Japan has ceased using PFAS-containing fire extinguishers, though prior investigations revealed contamination levels in reservoirs exceeding Japan's interim standards.
Japan's food safety panel has highlighted health concerns associated with PFAS, including:
Potential effects on birthweight and immunity.
Limited but concerning evidence regarding its carcinogenic potential.
Reported Spill:
On October 3, the US military reported to Tokyo officials that approximately 48, 000 liters of PFAS-contaminated water had overflowed during heavy rain on August 30.
