摘要
随着环境污染加剧,需要在水环境污染物监测方面有一种快速、灵敏、低廉的监测方法,以确保水资源的环境安全。本文选取国内比较常用的五种方法——发光细菌毒性实验法、斑马鱼毒性实验法、大型蚤类毒性实验法、藻类急性毒性实验法、蚕豆根尖微核法,以重铬酸钾(K2Cr2O7)配制成待测溶液测定水质毒性,通过实验比较了各种方法的灵敏性、准确性、可靠性。分析比较了这几种方法的优缺点和研究概况,并对存在的问题给出了建议,为加速国内水质检测应用提供了思路。
With the aggravation of enviromental pollution, a quickly, sensitive,inexpensive monitoring means should be developed to protect water resources. There are five domestic commonly used methods-photobaeteria testing method, brachydanio rerio testing method, large daphnia testing method, algae testing method, point of horsebean roots micronucleus testing method. In these methods water quality toxicity was tested by the solution of potassium biehromate （ K2 Cr2 O7 ）, through which sensitivity, accuracy, reliability of each method were compared. At the same time, the advantages and disadvantages and the general situation of these methods were summarized, and analysis and suggestions to existing problems were given. It provides ideas to accelerating the application of domestic water quality examination.
