Hair analysis receives a large amount of academic and commercial interest for wide-ranging
applications. However, in many instances, especially for elemental or 'mineral'analysis, the …

Metals and metalloids play important roles in plant function and metabolism. Likewise,
plants subsequently introduce vital dietary nutrition to people and animals. Understanding …

The absence of well-validated biomarkers of manganese (Mn) exposure in children remains
a major obstacle for studies of Mn toxicity. We developed a hair cleaning methodology to …

Three cleaning techniques that remove external contamination of human hair are assessed
to investigate the potential use of Sr and Pb isotope composition of hair for human …

Abstract The oxygen (18O/16O) isotope analysis of hair is commonly applied to reconstruct
an individual's residence history. However, region-of-origin as determined from oxygen …

The elements of human hair record specific information about an individual's health, diet,
and surrounding environment. Strontium isotope ratios of human hair have attracted interest …

Due to the straightforward and non-invasive sampling, ease of transport and long-term
storage and access to time-resolved information, determination of element concentrations …

A variety of techniques (secondary electron microscopy with energy dispersive X-ray
analysis, time-of-flight− secondary ion mass spectrometry, and synchrotron X-ray …

Abstract Natural variations of 87 Sr/86 Sr ratios in biological samples, such as human hair,
provide a biological record of provenance. Spatial distribution maps reflecting heterogeneity …

The isotope ratios of strontium (Sr) and lead (Pb) in water derive from local geology and their
isotopic signature can be linked to the age and type of underlying bedrocks and soils (if …
