Brun., 2010, LVIII, No. 2, pp. 299-302 Soils can be contaminated by high concentrations of phthalic acid esters (PAE) resulting from industrial and intensive agricultural activities. A plant receives water and substances (including pollutants) from soil by means of rootage. Water solution received by the roots is distributed in particular by means of xylem. Reception by means of fl oem is not very

Another possible way of pollutant entering into the plant is diff usion from atmosphere. Way of substance entering into the plant is decided by so called Henry constant as well as octanol-water partition coeffi cient. In case of phthalates, big diff erences between di-n-butyl phthalate (DBP) reception and dioctyl phthalate reception were detected. For example, DBP can enter into the plant by means of gas as well as liquid phase while dioctyl phthalate only by gas phase.
