摘要
非结核分枝杆菌（NTM）无处不在，可从家庭水源吸入，构成肺部NTM疾病的潜在风险。暴露于222 nm远紫外- c （far UV-C）的失活效率与254 nm紫外- c （UV-C）相当，同时使用专门的光学滤光片可显着提高人体皮肤和眼睛的安全性。NTM暴露于222 nm远紫外- c辐射下显示出辐照依赖性灭活作用，突出了其作为安全有效的水消毒的潜力。
Inactivating effect of 222-nm far ultraviolet-C radiation on nontuberculous mycobacteria
Nontuberculous mycobacteria (NTM) are ubiquitous and can be inhaled from household water sources, posing a potential risk of pulmonary NTM disease. Exposure to 222-nm far ultraviolet-C shows comparable inactivation efficiency to 254-nm ultraviolet-C, while employing specialized optical filters to significantly enhance safety for human skin and eyes. Exposure of NTM to 222-nm far ultraviolet-C radiation demonstrated an irradiance-dependent inactivating effect, highlighting its potential as a safe and effective for water disinfection.
