摘要: 以青海弧菌(Vibrio Qinghaiensis)、秀丽隐杆线虫(Caenorhabditis elegans)和热带爪蟾(Xenopus tropicalis)胚胎为研究对象,检测分析了龙泓涧和北里湖的水体及底泥的可能毒性.结果发现,绝大部分水样和底泥提取液对3种实验对象均未产生明显毒性效应.部分水体和底泥反而呈现出一定的正效应,表现为增强青海弧菌的发光强度,促进热带爪蟾胚胎发育.极个别水样对青海弧菌和秀丽线虫显示毒性,引起爪蟾胚胎轻微致畸效应,可能与污染物排放等偶然因素有关.结果表明,龙泓涧和北里湖的水体及底泥呈现较低的生态风险,西湖水体具有相对高的生物安全性.

Abstract: Using Vibrio Qinghaiensi, Caenorhabditis elegans and Xenopus tropicalis embryos, the potential toxicity of Longhong Ravine and Beili Lake were respectively detected. Results showed that water and sediments from Longhong Ravine and Beili Lake were not toxic to the three organisms. On the contrary, some samples showed positive effects, for example, enhanced luminous intensity 〖JP〗of Vibrio Qinghaiensis and promoted the growth of Xenopus tropicalis embryos. A small number of samples caused slight teratogenic effects on  Xenopus embryos, which were likely related to accidental discharges of pollutants. Our results suggested that Longhong Ravine and Beili Lake present relatively low ecological risks, which indicated high biological safety in West Lake.
