In January 1982, the EPA Office of Air Quality Planning and Standards released the final version of a staff paper which reviewed the scientific and technical basis of the national ambient-air-quality standards for particulate matter. The contents of this document had been reviewed and approved by the independent review board of EPA, the Clean Air Scientific Advisory Committee. The document contains a recommendation that the primary standards be based on thoracic particulate (< nominal 10 ..mu..m, TP) instead of total suspended particulate (TSP). From assessments of short- and long-term epidemiological data, it was concluded that the primary standards should be established within the range of 150 to 350 ..mu..g/m/sup 3/ on a 24-hour basis, and 55 to 110 ..mu..g/m/sup 3/ on an annual basis. The EPA staff paper also contains a recommendation of the International Standards Organization (ISO) that the ''ideal'' TP sampler should be one which mimics particle deposition patterns in the human lungs. Particle deposition curves estimated in the staff paper suggest that such a sampler should have a collection effectiveness of 10 ..mu..m D/sub 50/ (TP-D/sub 50/). Subsequent to this recommendation, TP-D/sub 50/ monitors became commercially available as the ''ideal'' TP sampler.
