Detailed comparison of extensive medical information (results of periodic medical examinations, of medical records of absence from work due to non-occupational illness, and of cumulative medical diagnoses) for workers with 20 years or more TEL service to a matched (for age, sex, race and length of service) group of workers with no occupational lead (TEL or other) exposure shows no significant health differences between the two populations. The conclusion is drawn that, under the conditions have existed at this facility, workers having long occupational exposure to levels of lead (chiefly TEL) sharply in excess of that of the general public, but within a range termed "safe" by current industrial medical standards, have not suffered detectable impairment of health.
对有20年或更长时间四乙铅（TEL）接触史的工人，与一组在年龄、性别、种族和服务年限上相匹配的无职业性铅（TEL或其他）接触的工人，进行广泛医疗信息（定期体检结果、因非职业病缺勤的病历以及累积医疗诊断）的详细比较，结果显示这两组人群在健康方面没有显著差异。得出的结论是，在该工厂存在的条件下，长期职业接触铅（主要是TEL）水平大幅超过一般公众，但在当前工业医学标准所称的“安全”范围内的工人，并未出现可检测到的健康损害。
