title: [Aminolcevulinic acid excretion in women before and after delivery and in their newborn infants (authors transl)].
abstract: A report is given on the excretion of variation of-aminolaevulinic acid (ALA) as an index of the lead load in pregnant women at term and at one and also at four weeks after delivery in both mothers and the newborn infants. The mean values in women were 7.2 + 3.7 before delivery 9.0 + 4.1 one week and 4.1mg ALA/1 urine four weeks after delivery; mean values of 5.2 + 3.2 one week after birth and 2.2 + 1.0 mg ALA/1 urine four weeks after birth were recorded in the newborn infants, according to the method of Davis and Andelman. Two groups were set up: mothers coming from the rural environs of Vienna and mothers living in the centre of the city. The ALA excretion was 14% lower in the former group (20% four weeks post partum) as compared with the mothers living in the city. When these data are considered against a threshold value of 10 ALA/1 urine (set up by the "Hauptverband der Berufsgenossenschafen", Bonn, West Germany, using the same method) the mean value of 9.0mg ALA/1 urine (with individual values of up to 17.4mg ALA/1 urine) in mothers one week after delivery already seems extremely serious.
