茂名炼油厂污水及其挥发物对生物机体影响的研究

The Effect of Wastewater and Substance of Volatility Sewage Treatment Plant on Biological Organism

茂名炼油厂污水对水生生物大型溞和白链鱼的48小时半数致死浓度均值分别为29.0％(9.4～57.3％)和18.3％(4.0～31.0％)。污水处理场对暴露28周实验大鼠有一定影响,主要表现为实验鼠肺巨噬细胞数和溶菌酶明显减少与对照组比较,差异有显著性P<0.01,实验组肝功能SGPT有增加趋势。提示应注意炼油污水挥发物对机体影响和防护。

The effect of wastewater and substance of volatility sewage treatment plant on biological organism is introuduced in this Paper.The results showed that 48h LC50 values of Daphnia and fish are 9.4~57.3% & 4-31% respectively.The mutagenic effect of wastewater was obtained by Ames test.The negative result was obtained.The me-le Wistar rats(body weight 120~150g)were used in the test ground.The rats were divided into expose and control grouPs,the time limit of experiment is for 28 weeks.The result displayed evidently decrease the number of PM(P<0.01)and SGPT increase in expose group.
