| 英文摘要 | Characteristic sexual hormones (SHs) and the factors that dominantly influence their occurrence in coastal ecosystems are less understood. This study verified the relationships between SHs and environmental factors and further inferred the possible controlling mechanisms of SH distribution. A characteristic pollutant of SHs was first proposed by determining the contamination level and ecological risks of SHs (seven species) in a coastal river adjacent to the Bohai Sea. The results showed that the 17 beta-oestradiol (17 beta-E2), estriol (E3), and 17a-ethynylestradiol (EE2) had high mean concentrations of 11.20 (+/- 1.31), 10.17 (+/- 4.91), and 16.71 (+/- 0.88) ng L-1, respectively, in the river water. The concentration of estrone (E1) was positively related to microbial substances of DOMs (p < 0.05). The humification index (HIX) had a negative relationship with E3 (p < 0.05). In water, the distribution of total SHs was regulated by the HIX and fluorescence index (FI), which might be related to photodegradation reactions. The 17a-oestradiol (17a-E2) and EE2 were related to humified organic matter, while E3 and androstenedione (ADD) were influenced by sewage input. The 17 beta-E2, E1, and 17 alpha-E2 may be derived from animal sources, while E3, ADD, EE2, and progesterone were from human activities. Oestrogens, including E1, 17 alpha-E2, 17 beta-E2, and EE2, displayed higher ecological risks than androgens and progesterone, with medium to high risk in most sites. The 17 beta-E2 was regarded as a characteristic pollutant of SHs throughout the river system, which displayed the highest risk. This paper may provide a reference for SH risk management and control. |
