| Abstract: | Using marsh tadpole as an object of study,acute and chronic tests of mercurywere carried out.Half lethal concentrations of mercury for the tadpole during 24 h and 48h were 0.304 and 0.226 mg/L respectively.The resuits showed that marsh tadpole washighly sensitive to mercury in water contacted and could be utilized as a means for biologi-cal monitoring of agrioecological environment. |
