[Rapid detection of toxic substances in water with ToxY-PAM].

A new type of dual-channel PAM fluorometer (ToxY-PAM) was developed for highly sensitive detection of toxic substances in water samples. In conjunction with suspension of unicellular algae as the biotest material, the ToxY-PAM provided a highly rapid and sensitive bioassay test system for the detection of toxic substances in water samples, which could directly or indirectly produce the inhibition of photosynthetic activity in algae. The development process of the detection of toxic substances in water with fluorescence technique, the basic principle and operation of the ToxY-PAM were reviewed in this paper.
