title: A study of blood lead levels in residents of the Sydney area.
abstract: Blood lead analyses were undertaken of 133 adults who were healthy blood donors, by means of the carbon rod atomic absorption technique. The mean result was 12-4 mug/100 ml and only two persons had values over 30 mug/100 ml. Subjects were divided into various groups and it was found that smoking did not contribute significantly to the blood level, but the location of dwelling and employment gave a correlation with proximity to the city of Sydney. In three separated groups of urban, suburban and city inhabitants, the use of the motor-car was associated with an increase in the mean blood-level of lead.
