“…For isotope analysis, it is recommended that the water sample be filtered into polysulfone filter media with a 0.45 µm pore size membrane. 44 Other authors 8,30,45,46 have also recommend acidifying the water samples with suprapur HNO 3 to pH<2. Bank et al 35 also examines the effect of filtration on surface water analysis.…”

“…[22][23][24][25][26] Stable isotopes (O and H) are considered as water isotopes, tracing the source and pathway of water molecules, while radiogenic isotopes (Sr and Pb) are solute isotopes, and trace the source and pathway of dissolved ions in the hydrologic cycle. 17,25 Some authors use isotopes to investigate atmospheric emissions, 26,27 sediments 28,29 and rain/snow, 9,[30][31][32][33] and others analyze superficial or sub-superficial waters 34 with higher Sr and Pb concentrations. [34][35][36] This paper is focused on urban groundwater that has pH values ranging from 5 to 7 and contains some suspended material.…”

Recebido em 10/5/07; aceito em 14/3/08; publicado na web em 26/9/08 Few articles deal with lead and strontium isotopic analysis of water samples. The aim of this study was to define the chemical procedures for Pb and Sr isotopic analyses of groundwater samples from an urban sedimentary aquifer. Thirty lead and fourteen strontium isotopic analyses were performed to test different analytical procedures. Pb and Sr isotopic ratios as well as Sr concentration did not vary using different chemical procedures. However, the Pb concentrations were very dependent on the different procedures. Therefore, the choice of the best analytical procedure was based on the Pb results, which indicated a higher reproducibility from samples that had been filtered and acidified before the evaporation, had their residues totally dissolved, and were purified by ion chromatography using the Biorad  column. Our results showed no changes in Pb ratios with the storage time.

“…[1][2][3][4][5] It is estimated that anthropogenic Pb pollution accounts for 96-99% of total atmospheric Pb deposition, 6,7) making emissions of this toxic heavy metal a major concern for human and ecological health. In Japan, based on the Pb isotope composition studies, motor vehicle exhaust, fly ash from municipal incinerators, 8) long-range transport from continental Asia, and natural component of soil 9) are considered as the dominant sources of the Pb in atmosphere.…”

“…11,[17][18][19] The isotopic composition of Pb in rainfall can be a powerful tool for monitoring the sources and transport of anthropogenic pollutants. However, since Pb isotope studies in rainfall or aerosols have generally been limited to bulk samples, 3,8,20,21) it has been difficult to discuss precisely where the Pb has originated from.…”

Rainfall at central Tokyo was sequentially collected with a 1-mm precipitation interval. Lead (Pb) concentrations and isotopic compositions of each fraction were precisely determined by an inductively coupled plasma-quadrupole mass spectrometry and a multiple collector-inductively coupled plasma-mass spectrometry, respectively. The results showed that (1) Pb concentration in rainfall decayed according to a power law function along with rainfall depth; (2) Pb isotope ratios clearly changed during a single rainfall event; (3) mixing model having four or more end members could explain the variations of Pb isotope ratio; (4) Pb in rainfall was probably affected by diesel vehicle emission control commenced on 1 st October 2003. Concerning (3), candidates of end member were estimated as local materials, e.g., natural soil components, airborne particle matter, automobile exhaust gases and fly ash from a municipal incinerator.

“…This ranges from the chemical quality of rain and snow to its effect on the marine and continental biosphere [1,2,3]. A major thread running through all the works is the study of global pathways and transport processes of trace metals, in particular heavy metals and toxic trace metals into the environment [4,5,6,7,8,9,10]. The determination of these elements requires analysis at trace or ultra-trace levels.…”

Figures of merit of pneumatic and ultrasonic sample introduction systems in inductively coupled plasma–multichannel-based emission spectrometry in an ultra-clean environment

Conventional figures of merit such as limits of detection, signal to background ratio or repeatability, are used to determine the performance of pneumatic and ultrasonic sample introduction systems in an ultra-clean environment with an axially viewed inductively coupled plasma-atomic emission spectrometry and multichannel detection. We observed that the ultrasonic nebuliser offered a large improvement of signal intensity (10-133 greater) compared to a cyclone chamber coupled with a pneumatic Meinhard nebuliser. This improvement is associated with an average increase of signal to background ratio by a factor 86 and an average decrease of detection limits by a factor 6. The improvement factors generally depend on the element and for the same element on spectral lines. Typically, the observed values of detection limits in this work are lower than those published and obtained in non-ultra-clean conditions. The results emphasize that the environmental conditions of cleaning and analysis are essential to avoid and control cross contamination of the samples and hence to obtain low detection limits.
