It is used in waste treatment to chemically reduce hexavalent chromium to trivalent chromium which can then be precipitated and removed from an aqueous waste stream.

The early Earth had a chemically reducing atmosphere.

The safety agency, which is headed by Mr. Pendergrass, estimated that the regulations would reduce chemically related injuries, illnesses and deaths in nonmanufacturing industries by 20 percent a year.

Under both scenarios, chemically reducing conditions adjacent to the borehole will reduce the transport of most radionuclides.

ABSMaterials' pump-and-treat system, the VOCEater, is a catalytic machine that captures and chemically reduces harmful and potentially carcinogenic chlorinated solvents into benign salts and gases.

The initial batch is melted together from silica, copper oxide, and other metal oxides to chemically reduce the copper ions to elemental copper.

Contaminants, that are mobile under chemically reducing conditions, such as radium, cannot be controlled.

If chemically reducing conditions are later disturbed for any reasons, the precipitated contaminants are re-mobilized.

When this is paired with the tendency of cancerous cells to contain higher levels of glutathione and a lower pH, a chemically reducing environment is created.

Protective atmosphere with chemically reducing properties can be beneficial in some cases.
