Comment on “Screening the Multi-element Content of Pleurotus Mushroom Species Using Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES)”

Abstract La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu are lanthanides, also referred to as “rare earth” elements (occurring at ultra-low concentration, i.e. each, ppb or lower levels) in plant animal foods including edible wild mushrooms. Could it be that lanthanides when collectively reported a summed value (widely REE) relatively high concentrations because extremely contributions from individual elements? REE naturally occur environmental media such the soil substrate which plants fungi grow characteristic pattern (Oddo-Harkins rule), with most of available literature confirming extension this fungi. Abnormalities therefore need examined closely resolved.
