Actual detection limits may vary due to sample <br /> matrix. <br /> CE - Compounds co-elute. Amount reported is total. <br /> NA - Not Applicable. <br /> ND - Indicates analyte was analyzed for but not detected. Unless otherwise stated, the <br /> method detection limit for each analyte is as reported in the "Detection Limit" <br /> column. Detection limits which are adjusted due to sample matrix or volume are <br /> stated where applicable. <br /> 1 - Cannot be separated from Diphenylamine. ' <br /> 2 - Quantitated as Azobenzene. <br /> References: <br /> a = EPA 600/4-79-020 <br /> b = SW846, 3rd edition <br /> C = Standard Method for Analysis of Water and Wastewater, 16th edition <br /> d = American Standard Testing Methods <br /> e = NIOSH, 2nd edition <br /> f = NIOSH, 3rd edition <br /> g = EPA 600/4-84-017 <br /> h = California DHS LUFT Manual <br /> Abbreviations: Units: <br /> Conc. = Concentration ug/L = Micrograms per liter <br /> Amt. = Amount ug/kg = Micrograms per kilogram <br /> mg/L = Milligrams per liter <br /> mg/kg = Milligrams per kilogram <br /> mg/cm3 = Milligrams per cubic centimeter <br /> mg/M3 = Milligrams. per cubic meter <br /> Quality Control Definitions: <br /> MS = Matrix Spike BS = Blank Spike <br /> MSD = Matrix Spike Duplicate BSD = Blank Spike Duplicate <br /> RPD = Relative Percent Difference RPD = Relative Percent Difference <br /> Rec. = Percent Recovery % Rec. = Percent Recovery <br /> RFD = 1MS-MSD1 x 100 RPD = IBS-BSDi x 100 - <br /> ((MS+MSD)/2) ((BS+BSD)/2) <br />
