| 中文摘要 | quinestrol has shown potential for use in the fertility control of the plateau pika population of the qinghai-tibet plateau. however, the environmental safety and fate of this compound are still obscure. our study investigated degradation of quinestrol in a local soil and aquatic system for the first time. the results indicate that the degradation of quinestrol follows first-order kinetics in both soil and water, with a dissipation half-life of approximately 16.0 days in local soil. microbial activity heavily influenced the degradation of quinestrol, with 41.2 % removal in non-sterile soil comparing to 4.8 % removal in sterile soil after incubation of 10 days. the half-lives in neutral water (ph 7.4) were 0.75 h when exposed to uv light (lambda = 365 nm) whereas they became 2.63 h when exposed to visible light (lambda > 400 nm). acidic conditions facilitated quinestrol degradation in water with shorter half-lives of 1.04 and 1.47 h in ph 4.0 and ph 5.0 solutions, respectively. moreover, both the soil and water treatment systems efficiently eliminated the estrogenic activity of quinestrol. results presented herein clarify the complete degradation of quinestrol in a relatively short time. the ecological and environmental safety of this compound needs further investigation. |
