日本多地检出永久性化学物

Core Viewpoint - A recent study in Japan indicates the widespread presence of per- and polyfluoroalkyl substances (PFAS) in sewage sludge from 34 wastewater treatment plants, suggesting potential nationwide contamination [3]. Group 1: Research Findings - Researchers from Kyoto University analyzed sludge from 34 out of approximately 2,200 wastewater treatment plants across Japan, confirming the presence of PFAS in all sampled locations [3]. - PFAS are known as "forever chemicals" due to their persistence in the environment and accumulation in human bodies, raising concerns about public health and environmental safety [3]. Group 2: Government and Public Response - The study's findings have prompted calls for the Japanese government to establish regulations regarding the levels of PFAS in sewage sludge [3]. - Since 2023, areas such as Okinawa, Osaka, and Tokyo have reported elevated PFAS levels in water bodies, with abnormal blood test results among nearby residents, particularly near U.S. military bases and Japan's Self-Defense Forces bases, which are suspected sources of contamination [3]. Group 3: Community Actions - Multiple civic groups in Japan have repeatedly requested investigations into pollution issues related to U.S. military bases, but these requests have not been addressed effectively [4]. - On the 12th of this month, a civic group in Okinawa submitted another application for an investigation into alleged pollution from the U.S. Futenma base affecting surrounding water bodies [4].
