title: Foundry air contaminants from green sand molds.
abstract: The major gases evolved from foundry molds have been determined in the laboratory. The principal gases evolved during pouring and shakeout of castings include hydrogen, carbon monoxide, carbon dioxide, methane and other low molecular weight hydrocarbons with smaller amounts of ammonia, hydrogen cyanide, and sulfur dioxide.
