About #EastPalestine in #Ohio. #Dioxins are a persistent pollutant They are released for example when burning plastic waste such as #PVC and the criteria is that the more chlorine is present in what is burned, the more dioxins are released
#VinylChloride is a precursor of PVC that when burning forms #HydrogenChloride vapor -boils at 48ºC- #CarbonMonoxide and #CarbonDioxide and very little #Phosgene
If chlorine volatilized in #HydrogenChloride,#Dioxins will be less of a problem
