【摘要】：目的探讨不同海拔的西昌和绍兴地区眼部暴露生物有效紫外辐射强度的差异,为眼紫外线防护提供依据。方法采用自行研制的旋转式眼紫外线暴露模型,在晴好天气下,分别在西昌和绍兴进行监测。运用AvaSoft 7.4 for USB2软件和OriginPro 8.0软件进行数据分析和处理。结果西昌和绍兴眼部生物有效紫外辐射暴露强度的日间变化呈双峰分布,西昌角膜、结膜和晶状体的加权UVBE最大值分别是绍兴的1.7倍、近2倍和1.8倍。相同太阳高度角下,西昌角膜、结膜、晶状体生物有效强度均高于绍兴。结论不同海拔两地区的眼部生物有效暴露强度的日间变化均呈双峰分布。相同太阳高度角下,其角膜、结膜和晶状体的生物有效紫外线强度存在明显差异,西昌均高于绍兴。
[Abstract]:Objective to explore the difference of effective ultraviolet radiation intensity of eye exposed organisms in Xichang and Shaoxing areas at different elevations, and to provide evidence for eye ultraviolet protection. Methods A rotating eye ultraviolet exposure model was developed and monitored in Xichang and Shaoxing in fine weather. AvaSoft 7.4 for USB2 software and OriginPro 8.0 software are used to analyze and process the data. Results the diurnal changes of the bioactive ultraviolet radiation exposure intensity in Xichang and Shaoxing eyes were bimodal distribution. The weighted UVBE values of Xichang cornea conjunctiva and lens were 1.7 times nearly 2 times and 1.8 times of those of Shaoxing cornea conjunctiva and lens respectively. The bioavailability of Xichang cornea, conjunctiva and lens at the same solar height angle was higher than that in Shaoxing. Conclusion the diurnal changes of the effective exposure intensity of ocular organisms in different altitude areas are all double peak distribution. At the same solar height angle, the bioavailable UV intensity of cornea, conjunctiva and lens were significantly different, and Xichang was higher than Shaoxing.
