A group of 200 Queensland adults without known health problems had in-vivo estimation of finger bone lead concentrations using X-ray fluorescence analysis (XRF). Forty of these subjects had elevated levels of bone lead of 25 ppm or more, consistent with exposure to the metal. Although the correlation between Queensland residence during childhood and raised bone lead levels was not significant, there were significant correlations between childhood residence in a painted wooden house and raised levels, and between occupational exposure and raised levels. Of the 40 subjects with elevated lead levels only two had neither a history of occupational exposure or childhood residence in a wooden house, whereas 11 of the 25 who had a history of both occupational and residential exposure were positive. The data are consistent with lead in housepaint, or absorbed during occupational exposure, being the two major sources of raised bone lead concentrations.
一组200名无已知健康问题的昆士兰成年人通过X射线荧光分析（XRF）对指骨铅浓度进行了体内估计。其中40名受试者的骨铅水平升高至25 ppm或更高，这与接触该金属相符。尽管童年时期在昆士兰居住与骨铅水平升高之间的相关性不显著，但童年时期居住在涂漆木屋与骨铅水平升高之间以及职业暴露与骨铅水平升高之间存在显著相关性。在40名铅水平升高的受试者中，只有两名既无职业暴露史也无童年时期居住在木屋的经历，而在25名有职业和居住暴露史的受试者中，有11名检测呈阳性。这些数据表明，室内油漆中的铅或职业暴露期间吸收的铅是骨铅浓度升高的两个主要来源。
