This terminology is only really used internally by the portal for generating URLs, it doesn't need to be exposed to the user.
The CSVs themselves use AirPollutant for the name (now: pl), AirPollutantCode for the URL containing the id (now: shortpl), and the portal refers to the "pollutant id" in the text.
The data dictionary calls them "pollutant notation" and "pollutant id"
