Comments for Sample AD22485 - Analysis $525 Westchester Dept, of Labs & Research User; Vinci, David L Date: 10-04-2001 Time: 14:19:06
Benzo(a)pyrene is present in this sample at an estimated level of 0.15 ug/L. Two additional unidentified polynuclear aromatic hydrocarbons with mass 252 may also be present at trace levels too low to confirm their identification by this method. Bis(2-Ethylhexyl)phthalate was present in the Laboratory Blank at 0.37 ug/L. The recovery for bis(2-Ethylhexyl)phthalate in the MDL Standard was above its acceptance range. The recoveries for Terbacil in the LCS Standard and the Spiked Sample were above their acceptance ranges. The Field Blank associated with this sample will be analyzed to support the Benzo(a)pyrene finding. This sample was submitted to our laboratory using NYCDEP bottles. A reinjection and analysis of this sample on 9/29/01 (with an increase in the electron multiplier voltage and recalibtation) yields Benzo(a)pyrene at an estimated level of 0.15 ug/L, as indicated by its retention time and mass 252. Some supporting mass spectra are present. The Laboratory Blank analysis was clean. The Field Blank analysis is reported under laboratory number AD23470. It was clean also for method 525.2.
