Description

METHYLMERCURY, TOTAL MERCURY AND OTHER TRACE ELEMENTS IN HUMAN HAIR
(METHYLMERCURY SPIKED) The materials were prepared from human hair which was donated to the IAEA. IAEA-085 represents hair with an elevated level of methylmercury (achieved by spiking the sample with methylmercury) whilst IAEA-086 is representative of the endogenous level for this analyte. The hair was cryogenically homogenized using the stainless steel “CryoPalla” mill at the KFA-Jülich Specimen Bank facility. The hair was subjected to consecutive millings, until approximately 70% had a particle size below 71 µm. These materials were γ-sterilized to ensure long-term stability of the material by inhibiting microbial action. keywords: biological materials , human tissue , hair , trace elements , heavy metals , mercury speciation , speciation analysis , organometallics |
