摘　　要：The observation on biophoton emission, free radical and toxicity of benzene to zebra fish and carp hepatic microsome has demonstrated that there is the corresponding relationship between them by means of 60 Coγ radiolysis. Free radicals play a key role in this relationship. A common photon originates of two biosystems are the excited species including singlet and triplet molecules (1O2 and C=0) as well as hydrocyclohexadienyl radical.OH and so on. OH, to a certain extent, directly participates in photon emission and toxicity of benzene to aquatic biosystems.These are the conclusions, but these are also problems. With the solution of the latters,model established in this work could be expected that it will be favorable for the development of photon-toxicology.The observation on biophoton emission, free radical and toxicity of benzene to zebra fish and carp hepatic microsome has demonstrated that there is the corresponding relationship between them by means of 60 Coγ radiolysis.
