* The "corrected values" here take an average normal sp. gr. as 1.015 for the human subject and facilitate comparison of individuals irrespective of water output. An average fluorine figure for human urine on city dietaries may be taken as anything up to 0.5 ppm., so long as the water-supply does not itself exceed this figure. When it does, the urine figures tend to approximate to the higher water-values (McClure and Kinser 1944). The domestic water used by this household contained 0.6 PPM ** For fluorine figures in various sources of London's water-supply, see Metropolitan Water Board (1936); Murray and Wilson (1945). |
