The objective of this epidemiologic study was to assess the relationship of blood lead levels to occupational exposure to the combustion products of leaded gasoline and to several lifestyle factors (smoking, alcohol consumption, and diet) among men from four occupational groups in Madras, India. Blood lead was measured using graphite-furnace atomic-absorption spectrophotometry. The mean (SD) blood lead levels in 129 blood samples collected from traffic police, bus drivers, and auto-shop workers were 11.2 (8.8), 12 (11.1), and 17.5 (8.4) µg/dL, respectively; the corresponding value for urban controls (office workers) was 4.1 (2.1) µg/dL. In a final multivariate regression model, a non-vegetarian diet and job category remained the strongest predictors of blood lead level (p < 0.05), while smoking, alcohol consumption, and duration of employment were not significantly correlated with blood lead levels. The authors conclude that continued use of leaded gasoline probably plays a dominant role in determining blood lead levels in Madras.
这项流行病学研究的目的是评估印度马德拉斯四个职业群体男性的血铅水平与职业性接触含铅汽油燃烧产物以及几种生活方式因素（吸烟、饮酒和饮食）之间的关系。采用石墨炉原子吸收分光光度法测量血铅。从交通警察、公交车司机和汽车修理店工人采集的129份血样中，血铅水平的均值（标准差）分别为11.2（8.8）、12（11.1）和17.5（8.4）μg/dL；城市对照组（办公室职员）的相应值为4.1（2.1）μg/dL。在最终的多变量回归模型中，非素食饮食和职业类别仍然是血铅水平最强的预测因素（p<0.05），而吸烟、饮酒和工作时长与血铅水平无显著相关性。作者得出结论，继续使用含铅汽油可能在决定马德拉斯的血铅水平方面起主要作用。
