中新网8月10日电 综合日媒报道，日本千叶县柏市等地水源中检测出有机氟化物（PFAS）超标问题引发关注。当地时间8月9日，千叶县政府及柏市政府公布了6月追加进行的水质调查结果，显示有4个区域的有机氟化物浓度超过日本暂定上限值（50纳克/升），其中一处超标420倍。
此次检测出的有机氟化物（PFAS）是一类难以降解的化学物质，其长期积累可能导致多种健康问题。日本方面表示，将继续调查超标原因，并采取措施确保饮用水安全。
PFAS是一类广泛使用的工业化学品，由于其化学稳定性高，在环境中难以分解，因此被称作“永久性化学物”。美国疾病控制和预防中心（CDC）的有关机构指出，PFAS可能导致包括肾癌、睾丸癌、胆固醇水平升高等一系列健康问题。
日本千叶县此次发现的水源有机氟化物超标情况，再次敲响了环境保护的警钟。随着全球对化学污染问题的日益关注，各国政府和相关部门需加强对水体和土壤等环境介质的监测，及时发现并处理潜在的环境风险，保障民众健康和生态环境安全。

Title: “Superseded by a factor of more than 420: PFAS contamination found in Chiba Prefecture’s water sources”

Aug 10, 2023 – Zhongxin.com – According to a comprehensive report by Japanese media, the issue of perfluoroalkyl substances (PFAS) contamination exceeding standards in water sources of Sakae City, Chiba Prefecture, has attracted attention. On August 9, the Chiba Prefectural Government and Sakae City announced the results of an additional water quality survey conducted in June, revealing that the concentration of PFAS in four areas exceeded Japan’s temporary upper limit value (50 nanograms per liter), with one site exceeding the limit by 420 times.
The PFAS detected in the latest survey is a class of chemicals that are difficult to decompose. Long-term accumulation of these substances may lead to a range of health issues. The Japanese side has stated that it will continue to investigate the cause of the contamination and take measures to ensure the safety of drinking water.
PFAS are widely used industrial chemicals that are chemically stable and difficult to decompose in the environment, earning the nickname “forever chemicals.” The U.S. Centers for Disease Control and Prevention (CDC) has noted that PFAS may cause a variety of health problems, including kidney cancer, testicular cancer, and elevated cholesterol levels.
The discovery of PFAS contamination exceeding standards in water sources of Chiba Prefecture serves as a reminder of the need for environmental protection. As global concern over chemical pollution grows, it is imperative for governments and relevant departments in various countries to enhance monitoring of water bodies and soil, promptly identify and address potential environmental risks, and ensure the health of the public and the ecological environment.
