Sažetak
The concentration of Lead in the ambient atmosphere was determined it 59 sampling sites in eight American cities during 12-month periods during 1968-71. Nineteen sampling sites had existed in 1961-62. The concentration of lead in the blood of specific well-defined populations Iiving in proximity to air sampling stations was also determined. Higher blood lead levels were associated with urban, as opposed to suburban, residence. and with smoking, as opposed to non-smoking. There was no significant concordance between the ranking, by site, of mean as lead levels and that of mean blood lead levels prevalent in the sampled populations. This observation suggests that factors other than the atmospheric lead level ace of .relatively greater importance in determining the blood lead levels in population groups.
