Abstract

Metabolism of the Persistent Plasticizer Chemical Bis(2-ethylhexyl) Phthalate in Cell Suspension Cultures of Wheat (Triticum aestivum L.

Fate of bis(2-ethylhexyl) [14C]phthalate in laboratory and outdoor soil-plant systems

“…in cell culture experiments, it was metabolized rapidly, predominantly to polar /S-D-glucosyl conjugates. The same occurred with mono(2-ethylhexyl) phthalate (Krell and Sandermann, 1986). For phthalic acid, which may be formed from DEHP in soil, it was shown that a significant uptake of UC from the 14C-labeled compound by plants occurred (Dorney et al, 1985).…”

“…This is in line with observations of Kato et al (1980) who did not find any DEHP in several plant species (Chrysanthemum coronarium, Brassica rapa, spinach) grown in DEHP-contaminated soil. Krell and Sandermann (1986) found that DEHP was not taken up into wheat cells when applied to wheat leaves but was partitioned or adsorbed to cuticles, triglyceride droplets, and cell wall components. When DEHP was taken up into plant cells, e.g.…”

“…Plant metabolism of DEHP in cell suspension cultures of wheat was reported by Krell and Sandermann (1986). However, uptake from soil by intact plants under environmental conditions has not been studied with 14C-labeled compound thus far.…”
