This study looked at measurements of lead (Pb) in a pilot population of environmentally exposed elderly residents of Shanghai, China and presented the first set of bone Pb data on an elderly Chinese population. We found that with environmental exposures in this population using K-shell x-ray fluorescence (KXRF) bone Pb measurements 40% of the individuals had bone Pb levels above the nominal detection limit with an average bone lead level of 4.9 ± 3.6 μg/g. This bone lead level is lower than comparable values from previous studies of community dwelling adults in US cities. This population had a slightly higher geometric mean blood Pb of 2.6 μg/dL than the adult US population. The main conclusion of this data is that in Shanghai there is environmental exposure to Pb, measured through blood and bone, which should be further investigated to assess the health impact of this exposure.
本研究观察了中国上海一批受环境影响的老年居民的铅（Pb）测量值，并提供了第一批关于中国老年人群的骨铅数据。我们发现，在该人群中，使用 K 壳 X 射线荧光（KXRF）骨铅测量，40%的个体的骨铅水平高于名义检测限，平均骨铅水平为 4.9±3.6μg/g。这一骨铅水平低于来自美国城市社区居民的同类研究的可比值。该人群的血铅几何均值（2.6μg/dL）略高于美国成年人群。这组数据的主要结论是，上海存在通过血液和骨骼测量的 Pb 环境暴露，应进一步调查以评估这种暴露对健康的影响。
