We mine and use vast amounts of metals and other raw materials at present. As a result, the natural geochemical cycles of a number of metals in the modern environment are altered, or even dominated, by anthropogenic activities. Recent developments in mass-spectrometry, in particular MC-ICP-MS and TIMS, allow us to measure isotope abundances of a number of metals with unprecedented precision and accuracy in various environmental and biological samples. The goal of this special issue is to create a forum to highlight new developments in using traditional (e.g., Sr, Pb, Nd) and non-traditional (e.g., Li, Mg, Si, Ca, Cr, Fe, Cu, Zn, Mo, Hg, U) isotopes for tracing metals from the environment to the human body. These recent advances can be highlighted with publications of new research findings on the following topics:
- Novel use of traditional radiogenic isotopes such as high-precision Pb isotopes or Sr or Nd isotopes for exploring exposure and metal sources to humans.
- Use of Hg and U isotopes for source identification and pathways for human exposure.
- Use of non-traditional isotopes, such as Li, Si, Mg, Cr, Fe, Zn, Cu, Mo for deciphering metal sources and pathways from the environment to humans.
- Analytical advances in measurements of traditional and non-traditional isotopes in environmental and biological samples.
- Theoretical considerations examining fractionation of non-traditional metal isotopes in environmental and biological samples.
In addition, reviews on any of the above topics are also welcomed. The ultimate goal of this Special Issue is to show how we can use isotope information to decipher what controls the abundance and isotopic composition of metals in the modern environment, and ultimately, how these metals enter the human body.

Abstract: Copper mining in Tongling has occurred since the bronze age and this area is known as one of the historic first places where copper has been and is extracted. Multiple studies have demonstrated, through concentration work on soils and waters, the impact of mining in the area. Here we present copper isotope and concentration values of 20 water samples (surface and groundwater) and 80 soil samples (15 different profiles ranging in depth from 0-2m) from proximal to distal (up to 10km) locations radiating from a tailings dam and tailings pile. Oxidation of the copper sulfide minerals results in isotopically heavier oxidized copper. Thus, copper sourced from sulfide minerals has been used to trace copper in mining and environmental applications. At Tongling, higher copper isotope values (greater than 1 per mil, which are interpreted to be derived from copper sulfide weathering) are found both in waters and the upper portions of soils (5-100cm) within 1Km of the source tailings. At greater than 1Km the soils do not possess heavier copper isotope values, however the stream water samples that have low copper concentrations (<10ppb) have heavier values up to 6.5Km from the source. The data suggest that copper derived from the mining activities remains relatively proximal in the soils but can be traced in the waters at greater distances.
