Therefore, the reporting limits for the GC/MS semivolatile <br /> compounds were raised. <br /> Due to sample matrix interferences observed during the extraction, the <br /> normal reporting limits were not attained. <br /> Due to the presence of an interferent near the retention time of <br /> acenaphthylene, the reporting limit was raised. This was due to the fact <br /> that the interferent had a significant abundance of ions at or near the <br /> mass of acenaphthylene. <br /> 07360 BTEX+MTBE by 8260B <br /> 05460 Benzene 71-43-2 N.D. 0.024 0.24 mg/kg 47.62 <br /> 05466 Toluene 108-88-3 N.D. 0.048 0.24 mg/kg 47.62 <br /> *=This limit was used in the evaluation of the final result <br />
