The following analytes are accepted based on this allowance: <br /> anthracene <br /> Due to the sample matrix an initial dilution was necessary to perform the <br /> analysis. Therefore, the reporting limits for the GC/MS semivolatile <br /> compounds were raised. <br /> 07360 BTEX+MTBE by 8260B <br /> 05460 Benzene 71-43-2 N.D. 0.026 0.26 mg/kg 51.55 <br /> 05466 Toluene 108-88-3 N.D. 0.052 0.26 mg/kg 51.55 <br /> 05474 Ethylbenzene 100-41-4 N.D. 0.052 0.26 mg/kg 51.55 <br /> 06301 Xylene (Total) 1330-20-7 N.D. 0.052 0.26 mg/kg 51.55 <br /> The GC/MS volatile analysis was performed according to the high level <br /> *=This limit was used in the evaluation of the final result <br />
