武汉市东湖抗生素污染现状及生态风险评估

摘要:
对东湖水域内16个点位进行采样,采用超高效液相色谱-三重四极杆质谱联用仪对28种抗生素做了污染现状调查及生态风险评估。研究发现,有20种抗生素在不同点位被检出,检出浓度由高到低为:喹诺酮类、氯霉素类和磺胺类,污染物检出情况总体呈现“南高北低,东高西低”的结果。考虑到东湖南部采样点位周边有多个农业种植、水产养殖和畜禽养殖地及其对东湖的潜在抗生素污染,证实了人类活动与抗生素污染密切相关。对抗生素采用风险商法做生态风险评估,结果表明,东湖南部采样点位的恶喹酸和氟甲喹的生态环境风险处于较低水平,其他抗生素的生态风险可以忽略。

Abstract:
The pollution status and ecological risk assessment of 28 antibiotics in 16 sites of East Lake were analyzed by UPLC-QQQ-MSD. 20 kinds of antibiotics were detected at different sites. The average detection concentration from high to low as quinolones, chloramphenicol and sulfonamides. The concentration of antibiotics showed high in the south and low in the north, high in the east and low in the west in this study. Considering that there are many agricultural planting, aquaculture and livestock and poultry farms around the sampling sites in the south of East Lake and their potential antibiotic pollution to East Lake, it is confirmed that human activities are closely related to antibiotic pollution. The RQ values were used to evaluate the ecological risk assessment, the results showed that oxolinic acid and flumequine were identified as low risk in the south of East Lake, while the risks of other antibiotics can be ignored.
