[Decrease of the lead burden of cattle within the last 20 years].
After introduction of many measures in technical and hygienic fields, emission of lead was remarkably reduced within the last years. Whether these measures were followed by a real decrease of the actual lead burden of man and animals may be recognized by controlling the lead content of food. Further it was possible to quantify a biological effect as an indicator of lead burden by the activity of delta-aminolevulinic acid dehydratase in red blood cells of cows in the Hannover area and to compare actual results with those obtained twenty years ago in the same region using identical methods. Results show a remarkable decrease of lead-caused inhibition of that enzyme.
