How can I see a numerical Pollution indicator?

[Peter34]

Is there some mod, that adds a Pollution meter to the game?An item you can place in a given chunk, and which then shows you how polluted that chunk is, not as a colour code but as an actual numerical figure?

You can use Debug mode (https://forums.factorio.com/wiki/inde ... Debug_mode) - tick "show_pollution_value".
