Products of particular interest are those in which a reportable chemical is either:
- present on its own or the main ingredient
- present in a simple mixture, typically less than 5 ingredients
Products containing less than 1% of any of the reportable chemicals, or fertilizers that are not labelled for nitrogen (N) content are, in general, of no concern.
The spelling of the chemicals is taken from the International Union of Pure and Applied Chemistry (IUPAC) nomenclature.
