Each lead ore deposit has its characteristic isotope ratios which are fixed during mineral ore genesis, and this unique property can be used to indicate the source of lead pollutants in the environment.
The use of environmental isotope ratios of 12C, 13C and 14C as indicators of the origins and behaviour of carbonaceous pollutants in atmosphere, soil and water was the subject of several papers.
Of novel interest and potential importance was the possibility of characterizing sources of organic carbon compounds in food and drink water on the. The results suggested that the (87)Sr/(86)Sr ratios could be used as a stable isotope tracer of waters and to provide information on the weathering processes.
Two major anthropogenic components of. Stable isotope ratios provide clues about the origins and transformations of organic matter. A few key reactions control the isotopic composition of most organic matter. Isotopic variations introduced Isotope ratios as pollutant source and behavior indicators book these reactions are often passed on with little change so that isotopic measurements can indicate natural pathways and flows “downstream” from these key by: The isotopic composition of lead in man and the environment in Finland – isotope ratios of lead as indicators of pollutant source.

rattus, n = 98) rats were Cited by: 7. Therefore, the lead pollution contribution rates cannot be regarded as the weight of lead isotope abundance ratios of each source.
This article concerns about the mathematical inaccuracies of Gobeil’s model, and a new analytical model of lead pollution sources identification will be established based on the lead isotopes mass : Tao Feng, Cheng-jun Wang, Yong Liu, Meng Chen, Miao-miao Fan, Zhi Li.
To characterize water quality in terms of dissolved elements and to investigate both the origin of the water and the source and behavior of groundwater contaminants in Metro Manila, 33 water (groundwater and surface water) samples were analyzed for ion and element concentrations, H and O isotope ratios (δD-H2O and δ18O-H2O), SO isotope ratios (δ34S-SO and δ18O-SO), and Sr isotope Cited by: Determination of boron isotope ratios by high-resolution continuum source molecular absorption spectrometry using graphite furnace vaporizers.

Title(s): Isotope ratios as pollutant source and behaviour indicators: proceedings of a Symposium on Isotope Ratios as Pollutant Source and Behaviour Indicators/ jointly organized by the International Atomic Energy Agency and the Food and Agriculture Organization of the United Nations and held in Vienna, November Carbon isotope ratios of atmospheric CO2 record exchange of carbon between the biosphere and the atmosphere; the incredible journeys of migrating monarchs is documented by hydrogen isotopes in their wings; and water carries an isotopic record of its source and history as it traverses the atmosphere and land surface.
Seasonal Behavior in CH 4 and CO Mixing and CH 4 Isotope Ratio Data  Data of CH 4 mixing ratio, δ 13 C‐CH 4, and δD‐CH 4 were analyzed for seasonal behavior. Long‐term trends were first removed by fitting each time series to a polynomial curve and detrending mixing and isotope ratio data with averages subtracted by: Stable carbon isotope ratios (C 13 /C 12) of man-made organic substances such as petrochemicals and pulp mill effluents are generally different from those of the “natural” organic matter in marine measuring the C 13 /C 12 ratios of background organic matter in the marine environment and the pollution sources, an estimate of the degree of man-made pollution Author: FC Tan, GJ Pearson.
This paper is primarily concerned with the measurements of Zn isotope ratios as a dietary indicator. Previous studies of zinc (Zn) isotopes in human blood highlighted strong differences between vegetarians and omnivores [ 8, 9 ], whereas the link between diet and blood iron (Fe) isotope compositions is unclear [ 8, 10, 11 ].Cited by: Ratios of the stable isotopes of nitrogen, 14 N and 15 N, can be helpful in differentiating atmospheric, wastewater, fertilizer, and pet waste sources (Abbene and others, ).

Oxygen isotope ratios (18 O and 16 O) in nitrate can be useful to distinguish the nutrient source and process where ratios of nitrogen overlap. In this way, the. Stable isotopes of carbon (δ13C), sulfur (δ34S), oxygen (δ18O), hydrogen (δ2H), nitrogen (δ15N), and radioactive isotope of hydrogen (tritium) have been applied in combination with conventional techniques (chemical) to investigate Karachi coastal water pollution due to Layari and Malir rivers, which mainly carry the domestic and industrial wastewater of Karachi by: 1.
The measurement of lead isotope ratios coupled with other trace element determinations on a spatial and temporal basis can potentially be used to differentiate between, and trace, the local and regional movement of aerosols from different sources of pollution.
By comparing the isotope ratios obtained for the MAS ( for Pb/ Pb) and STE-1 profiles ( for Pb/ Pb) are slightly different for each profile. This is an indication that the source of pollution may be different, either associated with petroleum product spills (e.g., gasoline, fuel oils) or other pollutant by: 8.
Particulate pollution from anthropogenic and natural sources is a severe problem in China. Sulfur and oxygen isotopes of aerosol sulfate (δ34Ssulfate and δ18Osulfate) and water-soluble ions in Cited by: An isotopic signature (also isotopic fingerprint) is a ratio of non-radiogenic 'stable isotopes', stable radiogenic isotopes, or unstable radioactive isotopes of particular elements in an investigated material.
The ratios of isotopes in a sample material are measured by isotope-ratio mass spectrometry against an isotopic reference process is called isotope analysis.
This book highlights new and emerging uses of stable isotope analysis in a variety of ecological disciplines. While the use of natural abundance isotopes in ecological research is now relatively standard, new techniques and ways of interpreting patterns are developing rapidly.
The second edition of this book provides a thorough, up-to-date examination of these methods of research. whereas the light/heavy isotopic ratio for magnesium and the five noble gases in the solar wind is higher than that in solar flares (Table 1).
This anomalous behavior of nitrogen isotopic ratios in the sun may be the first experimental observation that confirms the existence of a nuclear reaction, and identifies its location, in the sun.Basis for paleoclimate studies on ice cores, using oxygen isotopes: Vapour pressure of H2 16O is 10% higher than vapour pressure of HDO 1% higher than vapour pressure of HO Evaporation from a water body thus results in vapour that is poorer in the heavier isotopes deuterium and 18O, whereas the remaining water is enriched in D and 18O.
At equilibrium, atmospheric vapour .Isotope analysis is the identification of isotopic signature, the abundance of certain stable isotopes and chemical elements within organic and inorganic compounds.
Isotopic analysis can be used to understand the flow of energy through a food web, to reconstruct past environmental and climatic conditions, to investigate human and animal diets in the past, for food .
