Occupationally related lead exposure in the general population. A population study of 40-year-old men.
研究了哥本哈根郊区40岁男性居民的血液铅浓度与职业的关系，发现建筑、工业和运输业工人血铅较高，蓝领高于白领，但除铅冶炼厂工人外增幅较小。
Eighty-eight percent of all 40-year-old male residents of four suburban municipalities of Copenhagen County were examined for the lead concentration in their blood and interviewed regarding job category and place of work. Of the 504 men, 482 were currently employed, 18 were unemployed, and 4 were pensioners. The total median blood lead level was 13 micrograms/100 ml (0.6 mumol/l). Men employed in construction, industrial production, and transportation had the highest lead levels, while very low concentrations were found among pensioners and farmers. Blue-collar works had higher blood lead results than white-collar workers. Very high levels were found in two men employed at a secondary lead smelter, but otherwise increases in lead concentrations were comparatively small. However, the occupationally related, increased blood lead levels identified in this population contributed significantly to normal "background" levels.
