Description

Application

• TD-GC/MS analysis of indoor air pollutants (VOCs, PM) in hair salons.: This study highlights the application of thermal desorption-gas chromatography/mass spectrometry (TD-GC/MS) for detecting volatile organic compounds including xylenes in indoor environments like hair salons, contributing to occupational health studies (Kaikiti C et al., 2022).


• Environmental sampling of volatile organic compounds during the 2018 Camp Fire in Northern California.: Focuses on the monitoring of xylenes and other VOCs during wildfire events, providing data crucial for environmental impact assessments and public health advisories (Simms LA et al., 2021).


• A comprehensive air quality investigation at an aquatic centre: Indoor/outdoor comparisons.: Investigates xylenes and other air pollutants in an indoor aquatic center, comparing them to outdoor levels to assess ventilation efficiency and air quality control measures (Tolis EI et al., 2018).


• BTEX biodegradation by bacteria from effluents of petroleum refinery.: Examines the biodegradation of BTEX compounds including xylenes by specific bacteria strains, which is significant for bioremediation techniques and reducing environmental impacts of industrial effluents (Mazzeo DE et al., 2010).
