“…92 The resin was oven dried and analysed directly using an isotope ratio mass spectrometer coupled to an elemental analyser. Accelerator mass spectrometry (AMS) was used to measure 14 C in sea-water samples near radioactive waste dumping sites. 93 Data on 14 C and 3 H concentrations in samples from former dumping sites in the Atlantic and Pacific oceans are described and compared.…”

“…Goodsite and co-workers 7 used high resolution AMS to obtain 14 C dating of 'post-bomb' peat archives of atmospheric pollutants. They initially compared an extensive set of published experimental data that allowed them to generate a 14 C calibration curve for the northern hemisphere to a precision of 1-2 years. They showed that this new procedure offers a means of testing the validity of measurements made with the more conventional 210 Pb procedure that can be influenced by irregularities on the surfaces of peat bogs, e. g., variable trapping rate of radionuclide fallout material.…”

“…X-ray techniques such as PIXE continue to be widely used for the analysis of airborne particulate matter. 14,15 Beaulieu and co-workers improved the detection limit achievable with PIXE by reducing the signal contribution from the impaction substrate. 16 They achieved this by taking microscopic photographs of the aerosol deposits to determine the area of each deposit.…”

This is the twentieth annual review published in JAAS of the application of atomic spectrometry to the chemical analysis of environmental samples. In the analysis of air, there is ongoing development of instrumentation for continuous emission monitoring and as a means of interrogating the composition of individual airborne particulates. Developments in mass spectrometry applications continue to be an active area of research where the advantages of low detection limits and abilities to perform isotopic measurements are being exploited. There is growing interest in performing speciation measurements in water and this is being aided by the development of hyphenated techniques, most notably via the coupling of chromatographic systems to ICP-MS. Dominant themes in the analysis of soils include the optimization of preconcentration (and matrix separation) techniques, development of speciation protocols, notably arsenic and the increased use of portable XRF systems for in situ analysis. In geological analysis, laser ablation as an analytical tool is attracting a wider audience. Multi-collector ICP-MS is increasingly being used in a number of geological facilities to perform high precision isotope ratio measurements.

“…[41][42][43] The former approach cannot distinguish between internally and externally chemically mixed particle ensembles, but the full array of chemical analysis techniques may be applied off-line to collected samples. For particles still retained on the filter techniques include scanning electron microscopy, 44 Raman spectroscopy, 45 X-ray fluorescence (XRF), 46 X-ray photoelectron spectroscopy (XPS), 47,48 proton-induced X-ray emission (PIXE) 49 and instrumented neutron activation analysis (INAA). 50 Extraction into water permits analysis of inorganic ions by ion chromatography (IC).…”

Particles, air quality, policy and health

21 22The complexity of ambient particle composition considerably complicates pinpointing specific 23 causal associations between exposure to particles and adverse human health effects, the 24 contribution of different sources to ambient particles at different locations, and the consequent 25 formulation of policy action to most cost-effectively reduce harm caused by airborne particles. 26Nevertheless, the coupling of increasingly sophisticated measurements and models of particle 27 composition and epidemiology continue to reveal associations between particle components 28 and sources (and at lower concentrations) and a wide range of adverse health outcomes. This 29 article describes the current metrics, legislation and policies for protection of public health 30 from ambient particles, and reviews the current approaches to source apportionment of 31 particles and the latest evidence for their health effects. A particular focus is placed on particles 32 in the ultrafine fraction. The review concludes with an extended evaluation of emerging 33 challenges and future requirements in methods and metrics for understanding health outcomes, 34 and in the policy context. 35 36 For the research described here it is usually only the particle phase that is being discussed, to 44 which the word aerosol is sometimes erroneously applied (an aerosol being the combination of 45 the particles and the gas in which they are suspended). Instead, in line with correct usage, the 46 terminologies particle or particulate matter (abbreviated to PM), rather than aerosol, are used. 47 48A link between poor air quality and mortality has been recognised for centuries, becoming 49 particularly manifest as urbanisation and industrialisation intensified 3,4 . The source of air 50 pollution was formerly dominated by widespread coal and other solid-fuel burning, plus other 51 toxic emissions from largely unregulated industrial processes. In developed countries at least, 52 the extent of air pollution from such sources declined markedly with Clean Air Acts and 53 similar 'smoke control' legislation introduced from the mid-20 th century 5 , although these 54 remain important sources of air pollution in some parts of the world. From the latter part of the 55 20 th century, the coupling of increasingly sophisticated measurements of atmospheric 56 composition and epidemiological methods has continued to reveal associations between a 57 range of air pollutants (and at lower concentrations) and adverse health outcomes 4 . There is 58 recognition also of the multitude of sources and complex chemistry now contributing to poor 59 air quality, and the wider geographic scales of influence 5 . 60 61In the contemporary context, the deleterious impact of PM on air quality and health is 62 recognised by the World Health Organisation who publish advisory air quality guidelines for 63 ambient concentrations of PM (and other ground-level pollutants); see Table 1 6 . Many 64 countries or political blocs such as the European Union (EU) have developed polic...

This study addressed the identification and monitoring of pollution sources of terrestrial origin in rivers (domestic sewage and industrial effluents) and critical fluvial segments in highly polluted environments under tidal influence (mixing marine and continental sources) from Guanabara Bay Basin, Rio de Janeiro, Brazil. The mass balance of contaminants was determined in conditions of continuous flow (low tide) during dry season (lower dilution capability). The results allowed the evaluation of the potential of contaminant mass generation by the different river segments and the estimation of their natural and anthropogenic components. The water quality of Iguaçú and Sarapuí Rivers were evaluated for metals and biochemical oxygen demand. The method gave an excellent response, including the possibility of sources identification and contaminated river segments ranking. The approach also offers fast execution and data interpretation, being highly efficient.
