“…By using the scanning proton microprobe (SPM) facilities of the IRMM in Belgium and of the Lund Institute of Technology in Sweden, the major, minor and trace elements in individual giant North Sea aerosols were determined by µ-PIXE [18,19]. Titanium, vanadium, and chromium could be detected down to concentrations of 50 fg.…”

An overview is given of the recent applications of micro-analytical techniques to single particle environmental research performed at the University of Antwerp since 1990. Automated electron probe X-ray micro-analysis, laser microprobe mass spectrometry and micro-particle induced X-ray emission are the techniques most used for aerosol, aqueous suspension and sediment characterisation. Other techniques like scanning transmission electron microscopy, electron energy loss spectroscopy, Fourier transform infra red microscopy and secondary ion mass spectrometry have only recently been implemented into environmental research.

“…PIXE is another method with a trace characterization capability for particles with detection limits of the order of 1-10 mg g 21 . 56,[74][75][76][77] Other variants of nuclear microprobe techniques are still restricted to a few laboratories worldwide but can provide a wealth of information for individual particles. 56 m-PIXE uses a well focused proton beam and has been used for the single particle characterization of giant North Sea aerosols and other samples for major, minor and trace elements.…”

The characterization of particles, especially aerosol particles, is of great importance to many scientific fields. A relevant brief overview is given. A rigorous scheme of sampling and in-depth characterization of particulate samples has been developed in the authors' laboratories and by collaborative groups, including investigations by the following techniques: total reflection X-ray fluorescence spectrometry for quantitative bulk characterization; solid-state speciation by valence band X-ray spectrometry using electron microprobe or Mössbauer spectrometry (only bulk particle characterization possible); scanning electron microscopy and electron probe microanalysis for automatic semiquantitative single particle characterization of particles ≥ 0.5 mm; transmission electron microscopy for semiquantitative single particle characterization of particles with diameters down to 10 nm; high resolution-scanning electron microscopy, which is also capable of characterizing particles morphologically and qualitatively down to 10 nm in diameter; secondary ion mass spectrometry for the study of trace elemental distributions and isotopic ratios in particles with diameters above 1 mm. It is the aim of this paper to show the advantages and characteristics of this scheme of analysis to match today's requirements for topochemical methods of analysis. For this purpose a short overview of these methods for particle characterization is also presented.

After the industrial revolution considerable emphasis was placed on monitoring organic, inorganic and organometallic substances in the environment. Environmental contaminants include products of combustion, vapors, gases, industrial solvents, dusts, agricultural fertilizers, pesticides, radioisotopes, noise, ultraviolet light and certain microwave electromagnetic radiations. Contaminants that are present in strong enough concentrations to pose an immediate threat to life or to cause unmistakable cases of disease or acute poisoning are usually readily apparent, and experience has led to the development of adequate, but by no means perfect, environmental control measures. The effects of environmental contaminants are related to time as well as concentration or intensity. Time factors become increasingly important when low concentrations of contaminants do not produce ill effects until after months or years of exposure. Trace analytical methods, therefore, play a very important role in environmental analyses. They are required for the detection and identification of chemical pollutants present in the environment. It is essential that the analytical methods applied are suitable and that they yield reliable data. These methods have to have high sensitivity, as many toxic chemicals are present in environmental samples at microgram per liter levels. Furthermore they have to cover a large dynamic range, and most important they have to be inexpensive. Voltammetry fulfills all of these features and it can be used both in trace metal analyses and in the determination of organic compounds in environmental samples. This article will cover the determination of inorganic pollutants in air, water and soil, using electrochemical (EC) methods.
