摘要
探究磷化工厂周边水环境对水生生物的生态风险。以斑马鱼为受试生物,分析了某磷化工厂周边溪流水体中磷(P)、汞(Hg)在斑马鱼体内的累积状况及对斑马鱼生长体征和斑马鱼机体超氧化物歧化酶(SOD)活性、谷胱甘肽(GSH)含量和丙二醛(MDA)含量的影响。磷化工厂周边溪流水体中P、Hg的平均浓度均超过《地表水环境质量标准》(GB 3838—2002)限值,在溪流水体胁迫下,斑马鱼生长体征无显著变化;斑马鱼体内SOD活性对磷化工溪流水体的胁迫较敏感。磷化工厂周边溪流水体破坏了机体抗氧化系统的动态平衡,具有一定的生态风险。
In this study we explored the ecological risk of the water environment around phosphorus chemical plants on aquatic organisms.The accumulation of phosphorus(P)and mercury(Hg)in zebrafish(Danio rerio)in the stream water around a phosphorus chemical plant and its effect on the growth indexes,the superoxide dismutase(SOD)activity,the glutathione(GSH)content and the malondialdehyde(MDA)content of zebrafish were studied.The results showed that the average concentration of P and Hg in the stream water around the phosphorus chemical plant exceeded the limits provided in national standard GB 3838-2002.Under the stress of the stream water,the growth indexes of zebrafish did not change significantly.The SOD activity in zebrafish was more sensitive to the stress of the stream water around the phosphorus chemical plant.The stream water around the phosphorus chemical plant undermined the dynamic balance of the antioxidant system of zebrafish,posing a certain ecological risk.
