Probabilistic ecotoxicological risk assessment of heavy metal and rare
Rare earth elements (REEs) are emerging contaminants because of their global exploitation for use in the high-tech sector. Diffusive gradients in thin films (DGT) are an effective method for measuring the bioavailable component of pollutants. This study represents the first assessment of the mixture toxicity of HMs and REEs in aquatic biota ...

It is known that rare earth elements (REEs) comprise a homogenous group of elements in the periodic system. They include the elements scandium (Sc), yttrium (Y) and 15 lanthanides with successive atomic numbers from 57 to 71. In fact, the term "rare earth elements" is misleading because these elements are not rare.
