  • Sulfur Dioxide Basics | Sulfur Dioxide (SO2) Pollution | US EPA

    EPA’s national ambient air quality standards for SO 2 are designed to protect against exposure to the entire group of sulfur oxides (SO x ). SO 2 is the component of greatest concern and is used as the indicator for the larger group of gaseous sulfur oxides (SO x ). Other gaseous SO x (such as SO 3) are found in the atmosphere at concentrations much lower than SO 2 .

The report of the Task Force, which functioned under the auspices of the Defense Science Board, was published by The Rand Corporation in February 1970 for the Office of the Director of Defense Research and Engineering, Department of Defense. A slightly modified version of the report — the only omissions were two memoranda of transmittal from the Task Force to the Chairman of the Defense Science Board and onward to the Secretary of Defense — was subsequently published as Rand Report R-609, Security Controls for Computer Systems.
