| 摘 要： | 为了了解红霉素在水生生态系统的分布特征,正确评估红霉素的环境风险,采用微宇宙实验装置,考察了红霉素在模拟水生生态系统中水相、沉积物及生物体的分布特征.研究结果表明:红霉素进入模拟水生生态系统后,水相的半衰期为42d,沉积物为主要富集场所,可积累56.46%的红霉素;同时,水草和斑马鱼对红霉素亦有一定的吸收富集能力,水草(Elodea densa)和斑马鱼(Barchydanioreriovar)可分别吸收和富集1.04%和0.0402%的红霉素;水草对红霉素的富集能力高于斑马鱼,其最高富集系数在水草和斑马鱼内分别为46.05 L·kg-1和4.40L·kg-1,在考虑评估红霉素的生态环境风险时,应注意其对水生动植物的影响. |

| Abstract: | In order to understand the distribution of erythromycin in aquatic ecosystem and accurately assess the ecological risk of erythromycin in environment, the concentrations of erythromycin in water, sediment and biotas in a simulated aquatic ecosystem were investigated by aquatic microcosm. The results showed that the half-life of erythromycin in the aquatic ecosystem was 42 d; sediment could absorb 56.46% of erythromycin as the main accumulation place. Meanwhile, Elodea densa and Barchydanioreriovar could also absorb 1.04% and 0.0402% of erythromycin. The accumulation ability of Elodea densa would be higher than Barchydanioreriovar, and the highest bioconcentration factor was 46.05 L·kg-1 and 4.40 L·kg-1 individually. The risk on the aquatic biotas should be noted when assessing the ecological risk of erythromycin. |
