摘要

导言:户外工作者暴露于太阳紫外线辐射(UVR)的风险很高,这是一种已知的人类致癌物。在加拿大,没有针对职业环境的紫外线照射的客观测量方法。方法:户外工作者项目收集了2013年夏季加拿大温哥华户外工作者的UVR暴露数据。使用校准的电子紫外线辐射剂量计进行了为期一周的客观照射测量。从工人中收集皮肤癌风险因素、皮肤癌家族史和工作类型的其他数据;以及采样日的气象数据。建立了边际模型来检验工人、工作和气象因素对UVR暴露水平的影响,以标准红斑剂量(SED)测量。结果:招募了78名工人,其中73人至少有1天的测量UVR暴露。参与者大多是男性、年轻人和白种人。平均暴露(经重复测量校正)为1.08 SED。即使在同一工作场所,暴露量也有很大差异,范围从0.01 SED到19.2 SED。年龄较小、从事陆上建设工作以及天气预报较晴导致紫外线暴露水平较高。结论:在这项户外工作人员的研究中,能够引起晒伤的暴露水平是常见的,在一个通常与高日照无关的地方。

Levels of Occupational Exposure to Solar Ultraviolet Radiation in Vancouver, Canada.

Introduction: Outdoor workers are at high risk of exposure to solar ultraviolet radiation (UVR), a known human carcinogen. In Canada, no objective measures of UVR exposure are available for occupational settings.

Methods: The Outdoor Workers Project collected UVR exposure data among outdoor workers in Vancouver, Canada during the summer of 2013. Objective measures of exposure were taken for one week using calibrated electronic UVR dosimeters. Additional data was collected from workers on skin cancer risk factors, family history of skin cancer, and job type; as well as meteorological data for sampling days. Marginal models were constructed to examine the worker, job and meteorological determinants of UVR exposure levels, as measured in standard erythemal dose (SED).

Results: Seventy-eight workers were recruited, of which 73 had at least 1 day of measured UVR exposure for this analysis. Participants were mostly male, young and Caucasian. Mean exposure (corrected for repeated measures) was 1.08 SED. Exposure measures were highly variable even in the same workplace, ranging from 0.01 SED to 19.2 SED. Younger age, working in land-based construction, and sunnier weather forecasts led to higher levels of UVR exposure.

Conclusions: Exposure levels capable of causing sunburn were common in this study of outdoor workers, in a location not typically associated with high sun exposure.
