Abstract
Objectives: Volatile organic compounds (VOCs) are a type of pollutant that causes health risks and can be present in both indoor and outdoor environments. VOCs originate mainly from solvents and chemicals used at home or in offices and also from vehicle emissions. The current research work was aimed at the detection and quantification of VOCs indoor and outdoor at Sri Ramachandra Faculty of Pharmacy, Sri Ramachandra Institute of Higher Education and Research (DU), Porur, Chennai, Tamil Nadu, India. Material and Methods: Air was drawn through an adsorbent tube with a pump at a steady flow rate (100 mL min-1) for an hour to gather samples using the active sampling approach. Thermal desorption in combination with a gas chromatography (GC) analyzer was used to estimate the levels of hazardous VOCs, namely benzene, toluene, ethylbenzene, m-xylene, p-xylene, and o-xylene (BTEX) compounds. Results: VOCs were analyzed using the GC-mass spectroscopy technique. The finding shows the levels of BTEX as benzene (0.05–0.11 μg/m3), toluene (0.44–1.27 μg/m3), ethylbenzene (0.012–0.03 μg/m3), m-xylene (0.009–0.027 μg/m3), p-xylene (0.007–0.025 μg/m3), and o-xylene (0.003–0.019 μg/m3) compounds. Conclusion: The BTEX levels were observed to be well below the maximum acceptable limit. VOC emissions can be reduced by making process changes or by installing air pollution control equipment.
