• Uptake

In this study, tetracycline (TC) and degradation products in Phragmites australis grown in Kehli stream carrying municipal wastewater treatment plant effluents were determined. Phragmites australis plants are spread along Kehli stream. The concentrations of TC and degradation products were determined in roots, stems and leaves of the plants. Maximum TC, 4-epitetracycline (ETC), 4-epianhydrotetracycline (EATC) and anhydrotetracycline (ATC) concentrations were 31.5 +/- 1.5, 46.1 +/- 2.3, 27.0 +/- 1.3 and 16.5 +/- 0.8 ppb, respectively in roots while 8.3 +/- 0.4, 9.99 +/- 0.49, 6.6 +/- 0.3 and 4.69 +/- 0.23 ppb, respectively in stems. Maximum TC, ETC, EATC and ATC concentrations were 4.74 +/- 0.23, 5.58 +/- 0.28, 2.96 +/- 0.15 and 3.71 +/- 0.18 ppb, respectively in leaves. As a result, it was determined that Phragmites australis plants uptake TC and degradation products. The decreasing uptake order of Phragmites australis was determined as ETC > TC > EATC > ATC.
