{{Main|1930 Meuse Valley fog}}
In late 1930 and early 1931, several thousand cases of acute pulmonary attacks occurred in the Meuse valley, centered on Engis, and 60 people died. A commission of inquiry set up by the Belgian government concluded that the cause was poisonous waste gases, primarily [[sulfur dioxide]], emitted by the many factories in the valley and the furnaces used by the population, in conjunction with unusual climatic conditions coupled with the unique  topographic characteristics of the area.<ref>Mage, J., and Batta, G.
