Toxic Effect of Cadmium Material on Eisenia fetida

Abstract:

Utilizing international standards organization published the earthworm avoid behavioral responses to evaluate the quality of the soil experimental method standardization, we test the effect of six different concentrations of cadmium on the behavior of response of the earthworms (Eisenia fetida). After 24 hour and 48 hour respectively, the number of earthworms in the different quantity of the soil was counted. And at the same time, the earthworms were used to do a try-wrong learning behavior experiment, to research the relation between the earthworms treated with different concentrations of cadmium and memory time. The results showed that the earthworms like to stay in 50 mg/kg concentration in the soil.
