Research and Design on Portable and Fast Monitoring Instruments of Biological Toxicity

A kind of new-type fast tester of biological toxicity is introduced. This instrument is suitable for detecting biological toxicity of various toxicant, such as in the area polluted by waste water, bitumen, chemical, material and in the ocean by aquatic toxicity. The instrument design principle on the basis of detecting the emitting-light of the bacterium and the key technology of the designing requirement and the testing method are explained. Photmultiplier tube as photoelectricity detecting apparatus determines light intensity of sample doped photobacterium. The light intensity of photobecteria in the sample disturbed by the suspenders in container or other light color is proofread with light route compensator. Thus, exact monitoring and fast testing of biological toxicity is actualized.
