Examination of traffic policemen in Sydney showed that those exposed to motor vehicle emissions had blood lead levels within normal limits but marginally higher than those unexposed. Carboxyhaemoglobin levels depended only on cigarette smoking and were unrelated to exposure to motor vehicle emmissions.
对悉尼交警的检查表明,那些暴露于机动车尾气排放中的交警,其血铅水平在正常范围内,但略高于未暴露者。碳氧血红蛋白水平仅取决于吸烟情况,与机动车尾气排放暴露无关。
