Indoor Air BTEX Concentrations Measured in a Brazilian Laboratory

Air pollutant concentrations for benzene, toluene, ethylbenzene, and xylenes (BTEX) measured in an indoor combustion engine research laboratory. The data was collected by Paulo Cezar Piceli using passive tube samplers and analyzed via thermal desorption, gas chromatography, and mass spectrometry. Quantified concentrations were 4.64, 7.87, 10.47, and 21.36 parts per billion, respectively, from an eight-hour sampling period.

Use Cases

• Assessing human health risks from indoor air pollutants based on the quantified BTEX concentrations.
• Benchmarking indoor air quality in research laboratories against other studies based on the described methodology.
• Validating rapid sampling and analysis techniques for volatile organic compounds based on the eight-hour sampling period.
• Modeling exposure to petroleum-based air pollutants in occupational settings based on the combustion laboratory context.

Strengths

• Provides specific quantified concentrations for four key air pollutants: 4.64, 7.87, 10.47, and 21.36 ppb.
• Methodology is described in detail, including the use of passive tube samplers and thermal desorption/gas chromatography/mass spectrometry analysis.
• Sampling and analysis procedures were completed within a defined 16-hour timeframe.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Geographic coverage is limited to a single laboratory in Brazil, which may not be representative.
