Mount Reventino, a massif located in the Calabria Region of Italy, has several ophiolite outcrops of greenstone. These deposits are an important economical resource in the surrounding area. Some rock layers contain tremolite, a type of asbestos fibre.
The aim of this paper was to analyze the chemical and physical structure of the outcrops of Mount Reventino, and to assess and reduce the risk to workers associated with exposure to airborne fibres.
Personal and environmental samples were collected and analysed by Scanning Electron Microscopy equipped with energy-dispersive X-ray analysis.
The analysis of samples showed a difference in mineralogical features not only between the quarries under study, but also between the two opposite sides of the mountain. Exploitation of the quarries produces a fibre dispersion that is higher than the natural emission. Occupational exposure to asbestos fibres during greenstone transformation was confirmed by by the results of analysis of the collected samples.
This study made it possible to identify working activities with highest exposure to asbestos and establish the correct procedures to abate fibre dispersion, in order to reduce the correlated risk. Environmental samples collected in the urban area surrounding the quarries showed that the asbestos fibre concentrations were very low, however, further studies are needed in order to confirm these findings.
雷文科蒂诺山是位于意大利卡拉布里亚地区的一座地块，有几处蛇绿岩绿岩露头。这些矿床是周边地区的重要经济资源。一些岩层含有透闪石，一种石棉纤维。
本文旨在分析雷文科蒂诺山露头的化学和物理结构，并评估和降低与接触空气中纤维相关的工人风险。
采集个人和环境样本，并通过配备能量色散X射线分析的扫描电子显微镜进行分析。
样本分析表明，不仅在所研究的采石场之间，而且在山的两侧之间，矿物学特征都存在差异。采石场的开采产生的纤维扩散高于自然排放。采集样本的分析结果证实了在绿岩转化过程中工人职业接触石棉纤维的情况。
本研究使得识别石棉暴露最高的工作活动并建立减少纤维扩散的正确程序成为可能，以降低相关风险。在采石场周边市区采集的环境样本显示石棉纤维浓度非常低，然而，需要进一步研究以证实这些发现。
