Several species of small insects and animals have already been studied for their response to radioactive situations and their utilization as biomarkers. However, very few resources are available regarding Earthworms being utilized to decide soil conditions in highly contaminated Uranium (U)  sites. Worms were exposed to 5 different contaminated soil sites for 35 days and moistened periodically. Worms were then extracted and subjected to purge for 2 days. Worms were then subjected to various procedures to examine their U forms and concentrations. The purpose of these assays is to determine the effect of U on Bose earthworm’s uptake and bioaccumulation (Lumbricus Terrestris); Mortality rate, as well as the subcellular forms of U. The study will provide the scientific base for using earthworms as a bio-indicator of U eco toxicity in the ecosystem.
