摘要
A system for testing the toxicity of a test sample comprising: an aqueous suspension of dinoflagellates; a test chamber configured to contain the aqueous suspension of dinoflagellates and the test sample; an optical signal generator configured to emit an excitation signal for exciting the dinoflagellates to emit a fluorescence signal if the dinoflagellates are alive; a first optical transducer configured to produce a first data signal in response to detecting the fluorescence signal; a stimulator configured to introduce a gas into the aqueous suspension for stimulating the dinoflagellates to emit a bioluminescence signal if the dinoflagellates are alive; a second optical transducer configured to produce a second data signal in response to detecting the bioluminescence signal; and a processor configured to compare the first data signal and the second data signal to a control data to generate an output representing the toxicity of the test sample.
