摘要：A rapid,inexpensive enzymatie method is proposed for indirect water quality testing in terms of heavy metal toxicity. The activity of glucose-6- phosphate dehydrogenase was applied for heavy metal toxicity test as an effective crilerion in water quality. The toxicity of Pb (lead) and Cd (cadmium) for water flea,Moina macro- copa,were evaluated for 2- 8 days with variables of mobilization ability. And the reproduction impairment of Moina macrocopa were investigated as the parameter of chronie toxicity twst for Pb and Cd. As a result,the ECso for imbilization of Moina nwacrocopa were Pb and Cd were 1.6749 and 0.4683,respectively. The values of reproducive impairment to Moina macrocopa for Pb and Cd were 9.5938 and 8.3264 in ECso. A significant alteration of G6PDH (Glucose-6-phosphate dehydrogenase) activity of Moina macrocopa was observed when Cd and Pb were treated in media. The results obtained indicate that G6PDH activity of Moina macrocopa can be used as an indicative parameter in aquatic toxicity tests for heavy metals,.
