Abstract Over the past two decades, the term "heavy metals" has been widely used. It is often used as a group name for metals and semimetals (metalloids) that have been associated with contamination and potential toxicity or ecotoxicity. At the same time, legal regulations often specify a list of "heavy metals" to which they apply. Such lists differ from one set of regulations to another and the term is sometimes used without even specifying which "heavy metals" are covered. However, there is…

There is now an understanding that metallic elements can exist in many different chemical species, and that toxicity must be related to the precise nature of the toxic chemical species.
Definition of “Heavy Metals” and Their Role in Biological Systems
A heavy metal is defined as such mainly on the basis of its specific weight, but the application of the term “heavy metal” to an element often leads to an expectation that it is toxic. Therefore, it
Heavy metal: a misused term?
The use of the term “heavy metal” is regularly questioned by the scientific community. Here, we followed the evolution (1970–2020) in the number of published papers including this term in their

The relevance of the use of the term “Potentially Toxic Element(s)”, which needs more explicit endorsement, is highlighted, and the chemical elements that need to be considered are illustrated.
