Metabolite Identification
Common NameHafnium
DescriptionHafnium, also known as 72HF or hafnio, belongs to the class of inorganic compounds known as homogeneous transition metal compounds. These are inorganic compounds containing only metal atoms,with the largest atom being a transition metal atom. Hafnium is found, on average, in the highest concentration within a few different foods, such as common hazelnuts (Corylus avellana), black walnuts (Juglans nigra), and almonds (Prunus dulcis) and in a lower concentration in red beetroots (Beta vulgaris var. rubra), white cabbages (Brassica oleracea L. var. capitata L. f. alba DC.), and turnips (Brassica rapa var. rapa). Hafnium has also been detected, but not quantified in, a few different foods, such as cucumbers (Cucumis sativus), japanese pumpkins (Cucurbita maxima), and yellow zucchinis (Cucurbita pepo var. cylindrica). This could make hafnium a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Hafnium.
