Abstract
The distribution of arsenic in the stems of fruit trees grown in soils expo sed to arsenical pesticides has been studied using neutron activation analy sis. The results show arsenic to be confined mainly to heartwood near the p ith and active xylem tissue in the most. recent annual growth rings. These results suggest that dendroanalysis for arsenic in fruit trees will not yie ld a reliable chronology of arsenic exposure. (C) 2000 Elsevier Science Ltd . All rights reserved.
