%X Pollution of estuary water of five rivers in Qingdao. was assessed by Tradescantia micronuclei test. These rivers are Haibo River, Licun River, Banqiaofang River, Loushan River and Wantou River. This method was compared with the chemical method. The results are as follows. Tradescantia meiotic pollen mother cells chromosomes were found to be damaged from the wastewater of these five rivers. Chromosome breakage was induced. The chromosome segments became micronuclei on tetrad stage. Tetrads death was induced when the wastewater was highly poisonous. Frequency of micronuclei can be used as pollution index on tetrad stage. Lousan River is heavily polluted. Licun River and Haibo River are heavily polluted too. Banqiaofang River and Wantou River are lightly polluted. Results processed statistically for various pollutants were determined by chemical method. These results were in good agreement. This method can be used for bioassay purpose and used as complementary method for environmental pollution estimation by physical and chemical methods.
