A study to quantify the UV exposure of vineyard workers was carried out using polysulphone dosimetry. The study took place in Tuscany (Italy) involving 32 vineyard workers, covering three different stages of the vine's growth. The level of personal exposure expressed as a function on the available ambient UV radiation was determined. We also assessed skin reflectance parameters, pre and post exposure. It was found that during spring backs received between 53% and 87% of ambient exposure and arms between 30% and 60%. During summer, the workers received on the back between 36% and 77% of ambient exposure and between 19% and 43% of ambient exposure on the arm. The comparison with the occupational UV exposure limit showed that all subjects received UV exposures in excess of the limit. The exposure of back of neck exceeded 10 SED (assumed as a threshold level of sun-adapted skin for Mediterranean subjects) in spring, which means that in the case of non sun-adapted skin and without sun protection, erythema can be induced in this targeted population. The cumulative exposure was also estimated under specific assumptions of UV exposure giving values in some cases higher than previous studies.
采用聚砜剂量计对葡萄园工人的紫外线暴露进行了量化研究。该研究在意大利托斯卡纳进行，涉及 32 名葡萄园工人，涵盖了葡萄生长的三个不同阶段。根据可用环境紫外线辐射，确定了个人暴露水平的函数关系。我们还评估了暴露前后的皮肤反射率参数。结果发现，在春季，背部接受的环境暴露量在 53%到 87%之间，手臂接受的环境暴露量在 30%到 60%之间。在夏季，工人背部接受的环境暴露量在 36%到 77%之间，手臂接受的环境暴露量在 19%到 43%之间。与职业紫外线暴露限值的比较表明，所有受试者的紫外线暴露均超过限值。春季时，颈背部的暴露量超过了 10 SED（假设为地中海人群对阳光适应皮肤的阈值水平），这意味着在非阳光适应皮肤且没有防晒措施的情况下，该目标人群可能会出现红斑。根据紫外线暴露的具体假设，还估算了累积暴露量，在某些情况下，这些值高于以前的研究。
