Regulatory action levels for benzene in indoor air are typically unrealistic because they are commonly less than ambient outdoor concentrations. To trace potential benzene contributions to indoor air from outdoor sources, we evaluated data from 66 air samples collected at three sites with known subsurface impacts. Comparison of benzene:tracer ratios from indoor air, outdoor air, and soil gas samples demonstrated that indoor air benzene was primarily contributed by outdoor air and not by soil-vapor intrusion. Principal components analysis also demonstrated that soil gas had a distinctly different volatiles signature than both indoor and outdoor air. Ignoring ambient outdoor benzene contributions may lead to the erroneous conclusion that soil gas is the source of indoor air benzene. |
