Blood lead levels of children admitted to Sion Hospital, Bombay (India), from the adjoining Dharavi slum areas have been determined by proton-induced X-ray emission (PIXE). Blood samples were collected from 36 children with suspected lead poisoning and from 20 control children. The analysis showed that the lead concentration of the patients varied from 0.1 to 6.0 micrograms ml-1. In addition to lead, K, Ca, Fe, Cu, Zn, Se, Br and Rb were also detected simultaneously, of which the concentrations of Fe, Cu, Zn, Se, Rb and Pb were determined. The high blood lead levels of the children from this area may be ascribed to environmental pollution due to heavy vehicular traffic and industrial sources.
采用质子激发X射线发射（PIXE）分析法测定了印度孟买锡安医院收治的、来自毗邻达拉维贫民窟地区儿童的血铅水平。采集了36名疑似铅中毒儿童和20名对照儿童的血样。分析表明，患者的铅浓度在0.1至6.0微克/毫升之间。除铅外，还同时检测到了钾、钙、铁、铜、锌、硒、溴和铷，其中测定了铁、铜、锌、硒、铷和铅的浓度。该地区儿童血铅水平偏高可能归因于车辆交通繁忙和工业源造成的环境污染。
