Total Reflection X-ray Fluorescence (TXRF) is a well-established technique for chemical analysis, but it is mainly employed for quality control in the electronics semiconductor industry. The capability to analyze liquid and uniformly thin solid samples makes this technique suitable for other applications, and especially in the very critical field of environmental analysis. Comparison with standard methods like inductively coupled plasma (ICP) and atomic absorption spectroscopy (AAS) shows that TXRF is a practical, accurate, and reliable technique in occupational settings. Due to the greater sensitivity necessary in trace heavy metal detection, TXRF is also suitable for environmental chemical analysis. In this paper we show that based on appropriate standards, TXRF can be considered for non-destructive routine quantitative analysis of environmental matrices such as air filters. This work has been developed in the frame of the EU-FP6 PHIME (Public Health Impact of long-term, low-level Mixed element Exposure in susceptible population strata) Integrated Project (www.phime.org). The aim of this work was to investigate Mn air pollution in the area of Vallecamonica (Italy).
全反射 X 射线荧光（TXRF）是一种成熟的化学分析技术，但主要用于电子半导体行业的质量控制。该技术能够分析液体和均匀薄固体样品，因此适用于其他应用，特别是在非常关键的环境分析领域。与电感耦合等离子体（ICP）和原子吸收光谱（AAS）等标准方法的比较表明，TXRF 在职业环境中是一种实用、准确和可靠的技术。由于痕量重金属检测需要更高的灵敏度，TXRF 也适用于环境化学分析。本文表明，基于适当的标准，TXRF 可用于对空气过滤器等环境基质进行非破坏性常规定量分析。这项工作是在欧盟 FP6 PHIME（易感人群中长期、低水平混合元素暴露对公共卫生的影响）综合项目（www.phime.org）的框架内进行的。这项工作的目的是研究意大利瓦莱卡梅拉地区的锰空气污染。
