Primary teeth were analyzed by micro-SRXRF. The aim of this study was to determine the elemental distribution of lead and calcium in different regions of primary incisor of children living in a notoriously contaminated area (Santo Amaro da Purificação, Bahia State, Brazil). The measurements were performed in standard geometry of 45 degrees incidence, exciting with a white beam and using a conventional system collimation (orthogonal slits) in the XRF beamline at the Synchrotron Light National Laboratory (Campinas, Brazil).
通过微束同步辐射X射线荧光光谱法（micro-SRXRF）对乳牙进行分析。本研究的目的是确定生活在一个污染严重地区（巴西巴伊亚州圣阿马罗-达普里菲卡ção）的儿童乳切牙不同区域中铅和钙的元素分布。测量在45度入射角的标准几何条件下进行，使用白色光束激发，并在巴西坎皮纳斯国家同步辐射实验室的X射线荧光光谱线中采用传统的系统准直（正交狭缝）。
