The luminous bacteria method comprehensive toxicity analysis technology utilizes the fact that luminous bacteria can emit blue-green visible light with the wavelength of 450-. When the toxic substance in the object to be tested contacts with the luminous bacteria, the luminous intensity of the bacteria is changed immediately and is weakened along with the increase of the concentration of the toxic substance, and the change of the luminous intensity can be measured quantitatively by a precise photometer, so that the concentration of the toxic substance can be calculated according to the change of the luminous intensity.
