目的1995 - 2003年，由BAuA与K+S和IGF合作，对德国两个钾矿的矿工进行了纵向研究。目的是将接触数据与各矿山工人的矿工体检结果联系起来，并利用详细的接触调查作为公司进行风险评估的工具。在这段时间内，还开始讨论对健康的影响以及相应降低NO和NO2组分现有阈值限值的必要性。尽管该研究的流行病学方面在别处有报道（Lotz等人，方法在德国的两个钾矿中，分别进行了4次活动，对呼吸性粉尘、可吸入性粉尘、柴油颗粒物、一氧化氮、二氧化氮和二氧化碳的变化和短期暴露情况进行了调查。结果的报告和discussed.Results矿工，特别是在生产领域的矿山暴露于高度相关的混合物的成分，虽然暴露的情况可以被视为国家的最先进的和代表性的industry.Conclusion所有剂量反应的讨论必须考虑到，从来没有只有一个组件可以负责最终发生的呼吸效应。出于适当测量设备可用性的原因，应遵守可能降低欧盟指示性限值的限制。
Objective Between 1995 and 2003 a longitudinal study on miners in two German potash mines was planned and performed by BAuA in collaboration with K+S and IGF. Aim was to correlate exposure data to the results of medical examination of the miners in the respective mines' workforce and to use the detailed exposure investigation as a tool for risk assessment by the company. In this time period a discussion about health effects and the corresponding necessity to lower the existing threshold limits for the components NO and NO2 was started as well. Whereas the epidemiological aspects of this study are reported elsewhere (Lotz et al., in Int Arch Occup Environ Health, 2006), we discuss the exposure situation in detail in this paper.Methods In two potash mines in Germany the shift and short time exposure for the components respirable dust, inhalable dust, diesel particulate matter, nitrogen monoxide, nitrogen dioxide, and carbon dioxide was investigated in four separate campaigns. The results are reported and discussed.Results The miners especially in the production areas of the mines are exposed to a highly correlated mixture of the components though the exposure situation can be regarded as state of the art and representative for the industry.Conclusion All dose-response discussions must take into account that never only one of the components can be made responsible for an eventually occurring respiratory effect. For reasons of availability of proper measurement equipment limitations for a possible lowering of indicative limit values of the EU are to be observed.
