Description
|
Trace elements in human hair Over 6 kg of hair material has been collected. After washing and drying, it has been ground in a tungsten carbide mill under liquid nitrogen. The resulting powder passed a sieve with 80 µm apertures. A careful examination of the material under a magnifying-glass indicated that there were no pieces of hair of longer size which had passed the sieve longitudinally. The material was homogenised under argon in a closed mixing drum with PTFE lining for 2 weeks; It was bottled in glass bottles provided with screw caps and plastic inserts (appr. 10 g per bottle) after addition of a PTFE-ball to facilitate later rehomogenisation. keywords: Biological material, Human Tissue , Hair, Trace elements, Heavy metals |
