美军宣布，对其位于韩国平泽市的乌山空军基地展开的调查证实，基地内发现的物质并非白磷。[1]根据调查，发现的结晶体和残留物是环境暴露导致的无害表面腐蚀，未造成人员伤亡。[1]
事件始于7月28日，平泽市政府因怀疑基地发生白磷泄漏，向居民发送撤离警报文本信息，建议居民避免皮肤暴露。[1]美军随后完成除污工作，警报被撤销。美军第51战斗机联队司令Col. Ryan Ley表示："我们感谢市政府在保护社区安全方面的密切合作，也感谢各位在我们的团队解决此事期间的耐心。"[1]
美国在韩国部署约28,500名军人。[1]本周早前，8名韩国学生因闯入乌山基地并喊反美口号被拘留。[1]
The US military concluded its investigation into a suspected hazardous substance leak at Osan Air Base in Pyeongtaek, South Korea, finding no evidence of white phosphorus contamination.[1] On July 28, the Pyeongtaek city government issued evacuation alerts to residents after suspecting a leak at the facility, advising people to avoid skin exposure to potentially hazardous materials.[1] Following cleanup operations by US forces, the evacuation warning was subsequently lifted.[1]
According to the military's findings, crystalline residue and deposits discovered at the base contained no white phosphorus; instead, they were identified as harmless surface corrosion resulting from environmental exposure.[1] Colonel Ryan Ley, commander of the US 51st Fighter Wing, stated: "We appreciate the city's close partnership in keeping our community safe, and we thank everyone for their patience as our team worked to resolve this situation."[1] The investigation resulted in no reported casualties.[1] The United States maintains approximately 28,500 military personnel stationed in South Korea.[1] Earlier in the week, eight South Korean students were detained after entering the air base while chanting anti-American slogans.[1]
