This is the 33^th annual review of the application of atomic spectrometry to the chemical analysis of environmental samples. This update refers to papers published approximately between August 2016 and June 2017 and continues the series of Atomic Spectrometry Updates (ASUs) in environmental analysis that should be read in conjunction with other related ASUs in the series, namely: clinical and biological materials, foods and beverages; advances in atomic spectrometry and related techniques; elemental speciation; X-ray spectrometry; and metals, chemicals and functional materials. In the field of air analysis, highlights within this review period included the fabrication of new air samplers using 3D printer technology, development of a portable aerosol concentrator unit based upon electrostatic precipitation and instrumental developments such as a prototype portable spark emission spectrometer to quantify metal particles in workplace air. The advent of ICP-MS/MS systems has enabled analysts to develop improved methods for the determination of PGEs and radioactive elements present in airborne particles. With such instruments, the capacity to eliminate or minimise many isobaric interferences now enables analysts to forego the use of many onerous sample clean-up procedures. Improvements in the capabilities of aerosol mass spectrometers were noted as were developments in other complimentary measurement techniques such as Raman. In the arena of water analysis there are growing concerns regarding engineered NPs e.g. Ag NPs, entering water courses resulting in the development and optimisation of new methods based upon FFF and sp-ICP-MS techniques to measure such inputs. Similar concerns exist for MRI contrasting agents e.g. Gd-based compounds and here improved methodologies that involve the use of sample preconcentration using chelating columns and ICP-MS analysis have been proposed. In the field of plant and soil analysis, similar to developments in the water sector, there has been increased interest in the measurement of NPs. Many comparisons of sample digestion or extraction methods have been reported but a key issue rarely addressed is transferability, i.e. whether methods preferred by one group of researchers using particular apparatus are also optimal in a different laboratory using different apparatus. New sample preconcentration methods continued to appear although – as in previous years – the CRMs selected for method validation often failed to reflect the nature of the intended sample(s). A noteworthy advance is the use of HR-CS-ETMAS for elemental analysis. Developments in LIBS included greater use of TEA CO₂ lasers in place of Nd:YAG lasers and increased use of stand-off measurement. The past year has also seen a rise in proximal sensing using LIBS and pXRFS. In the field of geological analysis, the quest continues for well-characterised matrix-matched materials suitable for the calibration of elemental and, particularly, isotopic measurements by microanalytical techniques. Increasing interest in stable isotope analysis by SIMS is reflected by the number of matrix-matched RMs developed specifically for this technique. Much work continues on ways of improving isotope ratio measurements by ICP-MS and TIMS for a wide range of different isotope systems relevant to geochemical studies. High spatial resolution analysis by LIBS, LA-ICP-MS and SIMS to obtain data on chemical and isotopic variations in minerals and biogenic materials in two and three dimensions are the foundation for many new insights in geoscientific research. In XRFS and LIBS, the advantages and limitations of portable instrumentation continue to be major focus of activity.

原子光谱法更新–回顾环境分析的进展

这是33^日原子光谱法在环境样品化学分析中的应用的年度回顾。本更新是指大约在2016年8月至2017年6月之间发表的论文，并继续进行环境分析中的原子光谱更新（ASU）系列，应与该系列中的其他相关ASU一起阅读，即：临床和生物材料，食品和饮料; 原子光谱法和相关技术的进步；元素形态 X射线光谱法；以及金属，化学品和功能材料。在空气分析领域，本报告所述期间的重点包括使用3D打印机技术制造新的空气采样器，基于静电沉淀的便携式气雾浓缩器单元的开发以及诸如原型便携式火花发射光谱仪之类的仪器开发，以量化工作场所空气中的金属颗粒。ICP-MS / MS系统的出现使分析人员能够开发出改进的方法来测定空气中颗粒中的PGE和放射性元素。有了这样的仪器，消除或减少许多等压干扰的能力现在使分析人员可以放弃使用许多繁琐的样品净化程序。注意到气溶胶质谱仪功能的提高以及其他互补测量技术（例如拉曼）的发展。在水分析领域，对工程化NP的关注日益增长 ICP-MS / MS系统的出现使分析人员能够开发出改进的方法来测定空气中颗粒中的PGE和放射性元素。有了这样的仪器，消除或减少许多等压干扰的能力现在使分析人员可以放弃使用许多繁琐的样品净化程序。注意到气溶胶质谱仪功能的提高以及其他互补测量技术（例如拉曼）的发展。在水分析领域，对工程化NP的关注日益增长 ICP-MS / MS系统的出现使分析人员能够开发出改进的方法来测定空气中颗粒中的PGE和放射性元素。有了这样的仪器，消除或减少许多等压干扰的能力现在使分析人员可以放弃使用许多繁琐的样品净化程序。注意到气溶胶质谱仪功能的提高以及其他互补测量技术（例如拉曼）的发展。在水分析领域，对工程化NP的关注日益增长注意到气溶胶质谱仪功能的提高以及其他互补测量技术（例如拉曼）的发展。在水分析领域，对工程化NP的关注日益增长注意到气溶胶质谱仪功能的提高以及其他互补测量技术（例如拉曼）的发展。在水分析领域，对工程化NP的关注日益增长例如Ag NPs，进入水道导致基于FFF和sp-ICP-MS技术的新方法的开发和优化，以测量此类投入。MRI造影剂（例如基于Gd的化合物）也存在类似的问题，在此提出了改进的方法，包括使用螯合柱和ICP-MS分析进行样品预浓缩。在植物和土壤分析领域，类似于水领域的发展，人们对NPs的测量越来越感兴趣。已经报道了许多样品消化或提取方法的比较，但很少解决的关键问题是可转移性，即在不同实验室中使用不同仪器的一组研究人员首选使用特定仪器的方法是否也最佳？尽管与往年一样，新的样品预富集方法仍在继续出现，尽管与往年一样，为方法验证选择的CRM常常无法反映预期样品的性质。值得注意的进步是使用HR-CS-ETMAS进行元素分析。LIBS的发展包括更多使用TEA CO ₂激光器代替Nd：YAG激光器，并增加了对峙测量的使用。在过去的一年中，使用LIBS和pXRFS的近端感测也有所增加。在地质分析领域，人们一直在寻求特征明确的基质匹配材料，这些材料适合通过微分析技术对元素测量，尤其是同位素测量进行校准。SIMS对稳定同位素分析的兴趣日益浓厚，这是专门为该技术开发的基质匹配RM的数量所反映的。对于与地球化学研究有关的各种不同同位素系统，仍在通过ICP-MS和TIMS改进同位素比测量的方法上进行了许多工作。通过LIBS进行高空间分辨率分析，LA-ICP-MS和SIMS可以获取二维和三维的矿物和生物原料的化学和同位素变化数据，这是地球科学研究中许多新见解的基础。在XRFS和LIBS中，便携式仪器的优点和局限性仍然是活动的重点。
