    REEs are naturally found in very low concentration in the environment. Near mining and industrial sites the concentrations can rise to many times the normal background levels. Once in the environment REEs can leach into the soil where their transport is determined by numerous factors such as erosion, weathering, pH, precipitation, ground water, etc. Acting much like metals they can speciate depending on the soil condition being either motile or adsorbed to soil particles. Depending on their bio-availability RE
