Abstract

Asbestos is the term for silicate minerals with a typical fibrous structure that crystallises as separable fibres that can be released into the environment due to natural processes and anthropogenic activities. There is a need to intensify geo-environmental monitoring of the occurrence of natural asbestos on a global scale. The study of this material is essential to clarify the impact of asbestos on public health and to have an accurate knowledge of the requirements for asbestos replacement materials. The technical and ecological reasons for switching to these fibres are complex, as asbestos replacement materials are subject to considerable technological and economic demands, as well as demands for their biological safety.

The main objective of this paper is to establish a suitable methodology for detecting asbestos in soil sediments and accurately identify the different types from a range of samples.

Samples were analysed by electron microscopy and X-ray diffraction and compared with standards or available literature. The measurements demonstrated the presence of asbestos in the site sediments and identified specific types of asbestos.

The conclusion of this work is confirming the presence of asbestos in all samples, including its most dangerous types, which can cause severe diseases. In this context, the mechanism of asbestos-related diseases will be further addressed, which is linked to the size and shape of the individual fibres, the chemical composition of the asbestos types and the links between their basic structural units.

鉴定捷克共和国皮尔森地区土壤沉积物中的石棉纤维以及这些矿物对当地居民健康的影响

石棉是硅酸盐矿物的术语，具有典型的纤维结构，结晶为可分离的纤维，可因自然过程和人为活动释放到环境中。有必要在全球范围内加强对天然石棉发生情况的地质环境监测。对这种材料的研究对于澄清石棉对公众健康的影响以及准确了解对石棉替代材料的要求至关重要。改用这些纤维的技术和生态原因是复杂的，因为石棉替代材料受到相当大的技术和经济需求以及对其生物安全的需求的制约。本文的主要目的是建立一种合适的方法来检测土壤沉积物中的石棉，并从一系列样品中准确识别不同类型的石棉。用电子显微镜和x射线衍射对样品进行分析，并与标准或现有文献进行比较。测量结果表明，现场沉积物中存在石棉，并确定了特定类型的石棉。这项工作的结论是确认所有样品中都存在石棉，包括可能导致严重疾病的最危险类型。在这方面，将进一步讨论与石棉有关的疾病的机制，这与个别纤维的大小和形状、石棉类型的化学成分及其基本结构单位之间的联系有关。

期刊介绍： Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences. A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below. The scope of the journal includes: 1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes). 2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis. 3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification. 4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
