The fact that people do not trust the air is evident from the reports that the fire brigade receives. AT5 was also tipped off about the smell. “There is a chemical smell around Amsterdam and Diemen. Fire brigades are being called flat and they do not know what the cause is,” said a tipster. It is now clear that the smell is caused by the urea granules in the salt.
When urea comes into contact with air, it can be converted into ammonia, causing a pungent odor. The smell will disappear automatically after spreading. “If you don’t trust it, you can always call 112,” the fire brigade said.
