[Duration and course of pregnancy in women living in the region of the Police Chemical Plant (clinical data)].

In view of expected detrimental effects of fluorine and its compounds on pregnant women's organism, the duration and course of pregnancies have been compared in the "Police" Chemical Plant and control group. Immature deliveries and necrosed pregnancies in the "Police" Chemical Plant women were observed, though with no statistical characterisation. Perhaps the analysis of more ample material would indicate characteristic differences.
