Entry for Demo from demo since he'S having troubles with wikia atm to post comments:

As too few entries came in I'm going to participate myself. I'm using my entry in the last contest, but slightly revised. Pollution: Similar to a poison it supresses the healing ability of the liver. It can be inflicted by iron and other metal poisoning and pollutions in the air. Similar to the Frenzy status a gauge will appear that gets filled slowly when not treated. The more Pollution damage is done, the faster the gauge will fill. When full the status will take effect. The status will cause a longer time suffering poison, sleep or paralysis as well as 5% less healing effects for every healing item. So it is kinda a supportive status effect for other ones. The filling of the gauge can be reversed when eating an Appind (fruit that grows in the Orkan Plains) which is unlocked for sale with a villager request.

Like Frenzy it has a positive effect when cured before it reaches the full gauge. It will help to deal faster with other status effects (they last a shorter time) and the red portion of health gets healed faster. It gets cured when a set time interval passes which gets influenced by the battle. When you successfully hit a monster it shortens the time while if you get hit by an attack with the status effect it prolongs it. Another unique feature is that it can be inflicted by iron-infused substances like the sand in the Crimson Sands which means the monster doesn't need to directly inflict the status in these areas. Also all the monsters that use sand attacks would automatically inflict the status as well in these areas.

Any monster using sand attacks in the Crimson Sands automatically uses this ailment and some more monsters will be able to use it outside of this area. As it supports other status effects the whole potential can only be achieved when a monster in the area is able to use poison, paralysis or sleep or a monster outside can inflict both the ailment and poison paralysis or sleep or have another monster inflict it. But the 5% reduction of healing item effects will occur anyway.

The idea comes directly from the Crimson Sands/Mhalodona as it's designed to have red, meaning iron-infused, sand. So iron poisoning was the first notion of this idea. After reforming it a little to make it more regularly usable it came to the form as it is now. The name implies a pollution of certain organs, specifically the liver at most, what inhibits the function of it.
