[A placental transfer study of a pesticidal carbamate (sevin) in the rat (author's transl)].
After a single administration per os of a widely active carbamate pesticide : 1-naphthyl-N-methyl14C-carbamate (carbaryl) to the female rat on 19th day of pregnancy, 14C can be found into each foetus, as in placenta and amniotic fluid. This 14C activity, of important value compared to the one encountered into maternal organs, increases with time and reaches for each foetus 0,4% of the total activity given to the mother three days before. This activity's augmentation seems to be related to body-weight increment of great magnitude during the last period of pregnancy.
