The health of long service tetraethyl lead workers.

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.
