Tiger worms and 1080

Scientists used tiger worms (Eisenia fetida) to study the ecotoxicity of 1080 on soil. The earthworms lived in soil jars with concentrations up to 865 mg of 1080 per kg of soil (856 ppm). None of the earthworms died, and scientists detected little to no 1080 residues in earthworm tissue after 28 days of exposure.
