Acute Toxicological Effects of Imidacloprid Pollution on Earthworms
The acute toxicity of imidacloprid to earthworms (Eisenia foetida) was studied by OECD method. The results indicated that the LC50 of imidacloprid for earthworms was 0.036×10-3 mg/cm2 with contact filter paper test, 3.18 mg/kg dry weight with artificial soil test respectively. So imidacloprid was classified as a moderately toxic pesticide.
