摘要

防范COVID-19大流行和生物相关风险的需求日益增加,加上新技术的广泛可用性,导致在许多情况下广泛使用紫外线杀菌灯。安全是使用这些装置的一个主要问题,特别是在紧急情况下。皮肤和眼睛通常被认为是暴露于紫外线辐射(UVR)的靶器官。然而,在意外暴露于医院药房的杀菌灯后,在两名卫生保健工作者的口腔中也观察到不良反应。为了提供口腔意外紫外线辐射暴露的风险评估,进行了一项现场实验研究。一个成年人体模型被适应以不同的姿势再现真实的暴露。口腔暴露30分钟(工人在工作站工作时间的一半)。单位面积累积辐射能略高于ICNIRP指南(30 J/m2)规定的人体眼睛和皮肤8小时生物有效紫外线辐射暴露限值。根据人体模型的嘴唇,评估了100 J/m2的紫外线暴露。口腔内的高湿度和某些区域角质层的缺失可能会增强UV-C引起的上皮光损伤,这突出了暴露于人工UV-C辐射源对口腔的潜在不利影响。为预防和保护工人的健康,可以制定特定的UVR口腔黏膜暴露限值。

Oral cavity damage as a potential health risk from germicidal UV lamp use in occupational and emergency situations

The increasing needs for protection from COVID-19 pandemic and biological-related risks together with the broader availability of new technologies have led to a widespread use of UV germicidal lamps in many contexts. Safety is a major concern in the use of these devices especially in emergency situations. Skin and eye are commonly recognized as target organs for exposure to ultraviolet radiation (UVR). Nevertheless, adverse effects were also observed in the oral cavity of two healthcare workers after an accidental exposure to a germicidal lamp in hospital pharmacy. An experimental on-the-field study was set up to provide a risk assessment of accidental UVR exposure in the oral cavity. An adult manikin was adapted to reproduce real exposure in different postures. The oral cavity was exposed for 30 min (half of the time the workers spent at the workstation). The accumulated radiant energy per unit area was slightly above the limit for human biologically effective radiant exposure to UVR of eyes and skin within an 8-h period according to the ICNIRP guideline (30 J/m2). A UV-C exposure > 100 J/m2 was assessed in correspondence to the lips of the manikin. The high humidity presents in the oral cavity and the absence of the stratum corneum in some areas might enhance the epithelium photo-damage due to UV-C, highlighting a potential risk of adverse effects to the oral cavity from exposure to artificial sources of UV-C radiation. Specific UVR exposure limits for the oral mucosa could be developed to prevent and protect workers’ health.
