Dissimilarity in distributions of ocular exposure and environment spectrum irradiance of ultraviolet

  • 摘要: 目的 探讨眼部暴露与环境紫外辐射光谱的差异性,为指导公众正确防护眼部紫外线损伤提供依据。方法 使用自制的安装有高紫外灵敏度光纤光谱仪的眼紫外线暴露模型在中国海南省三亚地区进行实地监测,获得大量眼部暴露和环境紫外辐射光谱数据。眼部紫外辐射光谱数据与角膜损伤、结膜损伤、晶体损伤作用光谱相加权,计算对应的生物有效强度,再与时间相加权计算紫外辐射剂量。结果 环境紫外辐射随日间时间推移呈单峰分布,峰值出现在13∶00左右,而眼部暴露紫外辐射随日间时间推移呈双峰分布,峰值分别出现在10∶00和16∶00左右;不同波长光谱分布分析显示,随波长增加环境与眼暴露紫外辐射强度增加。环境400 nm正午峰值约为161.51 μw cm-2 nm-1,眼部400 nm上、下午峰值分别约为65.43和66.20 μw cm-2 nm-1。而眼角膜、结膜和晶体损伤光谱强度分别在311、300和307 nm出现峰值,10∶00辐射强度值高于其他时间点,峰值分别约为0.300 0、0.004 6和0.440 0 μw cm-2 nm-1结论 眼部暴露与环境紫外辐射光谱分布不同。
