Tab "Input" is a Chemical Specific and PACs list of chemical substances and sources, their Chemical Abstract Services Registry Numbers (CASRNs), and some physical constants. In addition, the conversion factor from ppm to mg/m³ is provided for the chemicals, which was carried out assuming normal temperature and pressure, 25°C and 760 mm Hg.(Future reviews will result in continuous updates to this data.)
Tab 2 "Rec TEELs" is a list of values ordered alphabetically by Chemical Name as presented in Tab 1, but only shows the PACs values and their Sources. They are provided in either ppm or mg/m³.
