Abstract

Objective

The effect marker club cell protein (CC16) is secreted by the epithelium of the small respiratory tract into its lumen and passes into the blood. Increased amounts of CC16 in serum are observed during acute epithelial lung injury due to air pollutants. CC16 in serum was determined as part of this cross-sectional study in underground potash miners on acute and chronic health effects from exposures to diesel exhaust and blasting fumes.

Methods

Nitrogen oxides, carbon monoxide, and diesel particulate matter were measured in 672 workers at a German potash mining site on a person-by-person basis over an early shift or midday shift, together with CC16 serum concentrations before and after the respective shift. CC16 concentrations and CC16 shift-differences were evaluated with respect to personal exposure measurements and other quantitative variables by Spearman rank correlation coefficients. CC16 shift-differences were modeled using multiple linear regression. Above-ground workers as reference group were compared to the exposed underground workers.

Results

Serum concentrations of CC16 were influenced by personal characteristics such as age, smoking status, and renal function. Moreover, they showed a circadian rhythm. While no statistically significant effects of work-related exposure on CC16 concentrations were seen in never smokers, such effects were evident in current smokers.

Conclusion

The small airways of current smokers appeared to be vulnerable to the combination of measured work-related exposures and individual exposure to smoking. Therefore, as health protection of smokers exposed to diesel exhaust and blasting fumes, smoking cessation is strongly recommended.

血清中的俱乐部细胞蛋白(CC16)是钾盐开采中柴油废气和爆破烟尘造成小气道上皮损伤的效应标志物
摘要 目的 小呼吸道上皮细胞向腔内分泌效应标志物俱乐部细胞蛋白(CC16)并进入血液。在空气污染物导致急性肺上皮损伤时,可观察到血清中的 CC16 含量增加。作为这项横断面研究的一部分,对地下钾盐矿工进行了血清中 CC16 的测定,以了解接触柴油废气和爆破烟雾对健康造成的急性和慢性影响。 方法 在德国的一个钾盐采矿场,对早班或中班的 672 名工人逐人测量了氮氧化物、一氧化碳和柴油微粒物质,并测量了各班前后的 CC16 血清浓度。通过斯皮尔曼等级相关系数评估了 CC16 浓度和 CC16 班次差异与个人暴露测量值和其他定量变量之间的关系。CC16 班次差异采用多元线性回归建模。作为参照组的地面工人与暴露在地下的工人进行了比较。 结果 血清中的 CC16 浓度受年龄、吸烟状况和肾功能等个人特征的影响。此外,它们还呈现出昼夜节律。虽然从未吸烟者的工作相关暴露对 CC16 浓度没有明显的统计学影响,但当前吸烟者的工作相关暴露对 CC16 浓度有明显影响。 结论 当前吸烟者的小气道似乎很容易受到工作相关暴露和个人吸烟暴露的共同影响。因此,为了保护暴露在柴油机废气和爆破烟雾中的吸烟者的健康,强烈建议戒烟。

期刊介绍: International Archives of Occupational and Environmental Health publishes Editorials, Review Articles, Original Articles, and Letters to the Editor. It welcomes any manuscripts dealing with occupational or ambient environmental problems, with a special interest in research at the interface of occupational health and clinical medicine. The scope ranges from Biological Monitoring to Dermatology, from Fibers and Dust to Human Toxicology, from Nanomaterials and Ultra-fine Dust to Night- and Shift Work, from Psycho-mental Distress and Burnout to Vibrations. A complete list of topics can be found on the right-hand side under For authors and editors. In addition, all papers should be based on present-day standards and relate to: -Clinical and epidemiological studies on morbidity and mortality -Clinical epidemiological studies on the parameters relevant to the estimation of health risks -Human experimental studies on environmental health effects. Animal experiments are only acceptable if relevant to pathogenic aspects. -Methods for studying the topics mentioned above.
