Air Pollution in Monster Hunter World (MHW) Iceborne is an Observation Log. Observation Logs are given by the Lynian Researcher located in Seliana which requires a Hunter to capture different photos for him.

The Plunderers of the Rotten Vale are used to a certain amount of effluvium, but I've been told that they can sometimes be spotted coughing in areas where the miasma is particularly dense. I could not possibly ask you to take them to such a hazardous place on purpose, but oh, the curiosity...
