Abstract

Eleven cases of green hair were collected and hair tips were analyzed in the electron microscope by energy-dispersive x-ray microanalysis. In all cases, remarkable copper concentrations could be demonstrated (0.2-1.8% w/w). In normal hair the concentration of copper was below the detection limit (0.02% w/w). Analyses of hair cross sections showed a concentration gradient from the periphery toward the center, the periphery having higher values. This observation is in agreement with suspected contamination of the hair with copper from extraneous sources: analysis of the tapwater in patients' homes showed elevated copper concentrations. In addition, the water showed aggressive properties (pH outside the recommended range, high nitrate concentrations, heavily chlorinated). Investigations by transmission electron microscopy showed damage in the endocuticula. Experimental studies of normal unaffected hair fibers showed that treatment with a copper salt alone could result in binding of copper to the hair but that the extent of copper binding could be greatly increased by damaging the cuticula with chlorinated water. It is suggested that aggressive water attacks copper tubings leading to increased copper concentrations in tapwater and causes cuticular damage, which facilitates entry of copper into the hair.

X-ray microanalysis in dermatology

Journal Article Forslind, B - Scanning Electron Microsc.; (United States)

The current trends in X-ray microanalysis as applied to dermatology are described by reviewing papers which have made a significant contribution to the field. Under separate headings, the analysis of hair, nail and epidermis is reviewed with an emphasis on quantitative results. Our recent work on green hair has revealed a higher than normal copper content derived from copper-containing tap and pool water. In nail the sulfur content was shown to be evenly distributed throughout the nail plate and the calcium content to be too low to influence on the ''hardness'' of the nail. Our study of nails from cysticmore »« less
Energy dispersive X-ray microanalysis, neutron activation analysis and atomic absorption spectrometry--comparison using biological specimens

Journal Article Wroblewski, R; Wroblewski, J; Lundstroem, H; ... - Scanning Miscroscopy; (USA)

X-ray microanalysis, neutron activation analysis and atomic absorption spectrometry were performed on normal and injured skeletal muscle. X-ray microanalysis of tenotomized rat soleus muscle showed significantly elevated levels of sodium and chlorine and lower potassium compared with normal muscle. Similar ion shifts could be demonstrated by neutron activation analysis and atomic absorption spectrometry. The concentrations of sodium and chlorine obtained by these techniques were somewhat higher and that of potassium lower than the values obtained by X-ray microanalysis. This can probably be attributed to the fact that in atomic absorption spectrometry and in neutron activation analysis the entire muscle biopsymore »« less
Quantitative X-ray microanalysis of biological specimens

Journal Article Roomans, G - J. Electron Micros. Tech.; (United States)

Qualitative X-ray microanalysis of biological specimens requires an approach that is somewhat different from that used in the materials sciences. The first step is deconvolution and background subtraction on the obtained spectrum. The further treatment depends on the type of specimen: thin, thick, or semithick. For thin sections, the continuum method of quantitation is most often used, but it should be combined with an accurate correction for extraneous background. However, alternative methods to determine local mass should also be considered. In the analysis of biological bulk specimens, the ZAF-correction method appears to be less useful, primarily because of the unevenmore »« less

Proteomic Characterization of Damaged Single Hairs Recovered after an Explosion for Protein-Based Human Identification

Journal Article Chu, Fanny; Mason, Katelyn; Anex, Deon; ... - Journal of Proteome Research

Evidence recovery is challenging where an explosion has occurred. Though hair evidence may be sufficiently robust to be recovered at the site, forensic analysis underutilizes the matrix by relying on morphological analysis. Where DNA is compromised, particularly in hair, protein-based human identification presents a promising alternative. Detection of amino acid polymorphisms in hair proteins as genetically variant peptides (GVPs) permits the inference of individualizing single nucleotide polymorphisms for identification. However, an explosive blast may damage hair proteins and compromise GVP identification. This work evaluates effects of an explosive blast on the hair proteome and GVP identification, investigates microscopy as amore »« less

X-ray microanalysis of freeze-dried and frozen-hydrated cryosections

Journal Article Zierold, K - J. Electron Micros. Tech.; (United States)

The elemental composition and the ultrastructure of biological cells were studied by scanning transmission electron microscopy (STEM) combined with energy dispersive X-ray microanalysis. The preparation technique involves cryofixation, cryoultramicrotomy, cryotransfer, and freeze-drying of samples. Freeze-dried cryosections 100-nm thick appeared to be appropriate for measuring the distribution of diffusible elements and water in different compartments of the cells. The lateral analytical resolution was less than 50 nm, depending on ice crystal damage and section thickness. The detection limit was in the range of 10 mmol/kg dry weight for all elements with an atomic number higher than 12; for sodium and magnesiummore »« less
