碩士 / 國立交通大學 / 環境工程所 / 88 / The transport and capacity of potentially hazardous chemicals in the natural environment have received increased attention in recent years, necessitating the development of bioassay systems. Toxicity testing with microalgae has been used extensively for assaying the impact on water quality. Now the general test is belong to Batch Test that consists in simpler and cheaper. But it requires 3 or 4 days to complete; therefore, it’s not suitable as a rapid screening method for measuring the toxicity of test materials.
The primary objective of our research is to design a short-term (<24-hr) algal assay which measured oxygen evolution. The new assay is feasible to evaluate metal and organic toxicity because it is a close system. Based on the test results, these parameters at initial cell density = 1.0*E+5, test time = 12hr, 100% medium strength and no chelator-EDTA are optimum. The performance (sensitivies) of the oxygen evolution test is between Batch and Continuous Test, employing six different metal toxicants. And our research is a trusting method from good correlation with other bioassay system.
