title: The excretion pattern of urinary fluoride in fertiliser workers.
abstract: An investigation was carried out into urinary fluoride levels of men working at an Auckland fertiliser works where the average of 45 workers was 2.2mg/1 (range 0.6-7.5) with the 12 men in the Manufacturing Department having an average level of 4.2mg/1 (range 1.5-7.5). Radiographic examinations of the skeletal system of the three subjects with the highest urinary fluoride levels showed no evidence of fluorosis. Early morning spot samples were found to be a reasonable indication of total 24-hour fluoride excretions.
