文摘
Land application of recycled manure produced from biosolids and reclaimed wastewater can transfer pharmaceutical chemicals to terrestrial environments, giving rise to potential accumulation of these residues in edible plants. In this study, the potential for plant uptake of 13 pharmaceutical chemicals, and the relation between the accumulation features within the plant and the physicochemical properties were examined by exposing pea and cucumber to an aqueous solution containing pharmaceutical chemicals. Ten of 13 compounds tested were detected in plant leaves and stems. Comparison of the plant uptake characteristics and the octanol鈥搘ater partition coefficient of pharmaceutical chemicals showed that compounds with an intermediate polarity such as carbamazepine and crotamiton could be easily transported to plant shoots. Moreover, these results suggest the possibility of highly hydrophilic pharmaceutical chemicals such as trimethoprim and sulfonamides to be accumulated in plant roots owing to their low permeability in root cell membranes.
