A variety of smokes and obscurants have been developed and used to screen armed forces from view, signal friendly forces, and mark positions. Smokes are produced by burning or vaporizing particular products.
Following concerns over exposure during training, the Office of the Army Surgeon General requested that the US National Research Council (NRC) review data on the toxicity of smokes and obscurants and recommend exposure guidance levels. Volume 2 evaluates data on the toxicity of four obscuring smokes: white phosphorus, brass, titanium dioxide, and graphite. This is the second volume in the series. Toxicity data and exposure guidance levels for diesel-fuel, fog-oil, red phosphorus, and hexachloroethane smokes were presented in Volume 1. Seven colored smokes were reviewed in Volume 3.

|3 Brass Smoke||45-67||(skim)|
|4 Titanium Dioxide Smoke||68-96||(skim)|
