p. 95-104 DISCUSSION SUR LE FACTEUR DE CONCENTRATION DU 32p DANS ENTEROMORPHA LINZA DE LA MER NOIRE LITORAL ROUMAIN O. Serbanescu Institut Roumain de Recherches Marines - Constanta Abstract The author analysed the variation of the accumulation rate of 32p in Enteromorpha Linza under variable salinity conditions and evaluated the ranges within which this ratio assumed normal values. Concomitantly, the saline composition of the vegetal fluid was deter- mined by the deep-frezing point method; this explained the physiolo- gical disturbances in the plant, having a direct effect on the radi- onuclides accumulation.
