The mean abundance of thallium in the earth's crust is approximately 1 ppm. Thallium occurs in small amounts in almost all living organisms. Natural levels in plants are reported as being between 0.01 and 3800 ppm ash weight, with 0.5 ppm being typical for most species. In nature it does not occur in the elemental state but is present as a trace compound in many minerals, mainly associated with potassium and rubidium.
