摘要
A toxicity test system comprising an aqueous suspension of dinoflagellates; a test chamber capable of containing the aqueous suspension and a test sample; an optical signal generator capable of emitting an excitation signal, which is capable of exciting the dinoflagellates to emit a fluorescence signal if the dinoflagellates are alive; a first optical transducer capable of producing a first data signal in response to detecting to the fluorescence signal; a stimulator capable of generating a pressure pulse, which is capable of stimulating the dinoflagellates to emit a bioluminescence signal if the dinoflagellates are alive; a second optical transducer capable producing a second data signal in response to detecting the bioluminescence signal; and an analyzer disposed to compare the first data signal and the second data signal to a control data to generate an output representative of the toxicity of the test sample.
