This study was designed to assess the blood levels of cadmium and lead in some occupationally exposed individuals and compare the values with non-exposed individuals, with the aim of increasing the awareness of health risk caused by these heavy metals. A total of 120 subjects (64 occupationally exposed and 56 non-exposed subjects) with the age range of 15-40 years were studied in cross-sectional study conducted between September 2012 and February 2013 in Gwagwalada area of Abuja, Nigeria. Blood cadmium and lead were analyzed using an atomic absorption spectrophotometer (AAS). The respective mean blood levels of cadmium and lead were 11.63±1.73 μg/dl and 45.43±6.93 μg/dl in occupationally-exposed subjects, while in non-exposed subjects 2.03±0.55 μg/dl and 12.08±2.87 μg/dl. The results show that occupational exposure increases the blood level of cadmium and lead, which consequently increases the health risk of the exposed individuals.
本研究旨在评估一些职业暴露个体的血液中镉和铅的水平，并将这些值与未暴露个体进行比较，以提高对这些重金属所造成健康风险的认识。在2012年9月至2013年2月于尼日利亚阿布贾瓜瓜拉达地区进行的一项横断面研究中，共对120名年龄在15至40岁之间的受试者（64名职业暴露者和56名未暴露者）进行了研究。使用原子吸收分光光度计（AAS）分析血液中的镉和铅。职业暴露受试者中镉和铅各自的平均血液水平分别为11.63±1.73μg/dl和45.43±6.93μg/dl，而在未暴露受试者中分别为2.03±0.55μg/dl和12.08±2.87μg/dl。结果表明，职业暴露会增加血液中镉和铅的水平，从而增加暴露个体的健康风险。
