说明

应用

• Environmental sampling of volatile organic compounds during the 2018 Camp Fire in Northern California.: This study analyzed volatile organic compounds, including o-Xylene, sampled during the 2018 Camp Fire in Northern California, highlighting the analytical methods used to assess environmental exposure and chemical composition in wildfire scenarios (Simms et al., 2021).


• Urinary BTEX, MTBE and naphthalene as biomarkers to gain environmental exposure profiles of the general population.: Focuses on the use of urinary biomarkers, such as BTEX (including o-Xylene), for assessing environmental exposure in populations, demonstrating the integration of analytical chemistry techniques in epidemiological studies (Fustinoni et al., 2010).


• Genotoxic effects of volatile organic compounds in a chemical factory as evaluated by the Tradescantia micronucleus assay and by chemical analysis.: Investigates the genotoxic effects of VOCs, including o-Xylene, in a chemical plant environment, using both biological assays and chemical analysis to evaluate risk and exposure (Kim et al., 2003).


• Time-gated pulsed glow discharge: real-time chemical speciation at the elemental, structural, and molecular level for gas chromatography time-of-flight mass spectrometry.: This paper presents a novel analytical technique for real-time chemical speciation, useful in analyzing compounds like o-Xylene, providing insights into complex analytical methodologies in chemistry (Lewis et al., 2003).
