Local identifier:  TOP385
Synonym Term:  bark Ni content per dry mass

Definition:  The ratio of the quantity (SEP:quantity) of nickel (CHEBI:nickel atom) in the bark (PO:bark) to the corresponding bark (PO:bark) mass (PATO:mass) assessed after drying
Formal Unit:  mass unit / mass unit or amount unit / mass unit

Comment:  The quantity of nickel can be expressed either as a mass (with mass unit, e.g. gram) or as an amount (with amount unit, e.g. mol). The term concentration is polysemic and we suggest to not use it in this context.
