The oxidizing fluxes usually include cupric oxide or manganese 'dioxide' , which decompose at copper alloy melting temperatures to generate the oxygen required.

Previously, only the electricity sector and non-ferrous smelting industry were subject to the limits on nitrogen oxide and sulphide 'dioxide' , two of the most notorious and significant contributors to smog.

The clay body is held together firmly by the collapsed molecules of aluminum 'dioxide' and silicon oxide, which intermesh like a basket weave.

High concentrations of nitrogen oxides, carbon monoxide, sulfur 'dioxides' , and lead apparently often cancel the need for traditional blue.

Plastic production is water-intensive and causes air emissions of hydrocarbons, sulfur oxides, carbon monoxide, nitrogen oxides, and carbon 'dioxides' .
