HIGH LEVEL OF ARSENIC REAFFIRMED FOR HUMAN HAIRS IN MONGOLIA

摘要

We have analyzed the hair of inhabitant of a district in Mongolia where the arsenic contamination isndoubted. The study area includes a village where the authors noticed possible arsenic contaminationnin 2004 (S. Murao, B. Tumenbayar, K. Sera, S. Futatsugawa and T. Waza, Finding of high levelnarsenic for Mongolian villagers’ hair, Int. J. PIXE 14 (2004) 125–131). The investigation teamnvisited each family, explained the purpose of visit, obtained their consent, and cut the untreatednvirgin hairs. The result reaffirmed high arsenic concentration, up to 11ppm, for most of the subjects.nSince the arsenic anomaly in the study area is observed regardless the occupation, it is highlynprobable that the area is contaminated on a regional scale.
