Table 5. Concentrations of selected polycyclic aromatic hydrocarbons measured by semipermeable membrane devices (SPMDs) at three sites in the McKenzie River basin, Oregon, September–October 2007.
[A and B are replicate samples. MDL, method detection limit; MQL, method quantitation limit; “<,” compound not present at MDL; NQ, not quantified--compound detected at a level less than the MQL; detections are highlighted as bold type in shaded cells]
