Abstract

Four sediment cores consisted of 30cm of undisturbed sediment and 60 cm of overlying water collected from two sites within a natural reservoir were designed and the behavior of 17β-estradiol (E2) spiked into the overlying water of the sediment cores was investigated. Besides, with the addition of glucose, the likely effect of easily degradable organic substrates upon the behavior of E2 and its biotransformation intermediate of estrone (E1) was also assessed. The results showed that the spiked E2 (at 16.5 μg/L) disappeared faster in aerobic sediment cores than in anaerobic ones, and under both aerobic and anaerobic conditions, E1 was formed as the biotransformation by-product of E2 and then disappeared from the water phase in a pace considerably slower than E2. The half-lives of E2 without and with the coexistence of glucose (added at three different concentration levels) varied in 0.4-7.5 hours for runs of the aerobic cores, while those for runs of the anaerobic cores in 2.7-15.1 hours. The removal of glucose quantified using the index of TOC was also found faster in aerobic sediment cores than in anaerobic ones.
