Abstract
Synchrotron microscopic X-ray fluorescence (μ-SRXRF) scanning and conventional XRF analysis were applied for studying elemental concentrations in lyophilised brain rat slices. The animals received drinking water—100 ppm of sodium arsenite—ad libitum for 30 and 60 days. Accumulation of arsenic was corroborated and its dependence with arsenic dosage suggests the existence of a protection mechanism which limits the transport of inorganic arsenic to the brain. Chlorine, potassium and iron were reduced changing their spatial distributions while copper and zinc were redistributed.
