Adds the pollutant to the surface properties of all supported planets. This can be used just for the additional information or for surface conditions. ## Usage Internally each pollutant is assigned a unique ID. If you want to add a surface condition for a specific pollutant, use that ID as the only allowed value. ### Example ```lua { type = "assembling-machine", name = "active-noise-cancelling-tower", surface_conditions = { { property = "pollutant-type", min = 3, max = 3 } } } ``` ### Pollutants 1.
