ABSTRACT

Air pollution is associated with several detrimental health conditions. This study assessed comfort parameters, priority air pollutants, hydrogen sulphide (H₂S), non-methane hydrocarbons (NMHCs), and volatile organic compounds (VOCs) in natural science departments in a university to understand their role in air pollutant concentrations in university environments and associated health risks. Levels of air pollutants in the departments varied. High CO₂ concentrations existed in all departments with highest levels of NMHC and VOC observed in the biochemistry, microbiology and biotechnology (BMBT) department. Highest Air quality index value of 111.3 was recorded for NO₂ in the BMBT department. Health risk associated with exposure to these pollutants was highest for occupants in the physiology, followed by the biodiversity, and finally BMBT department. Natural science departments seem to contribute significant amounts of H₂S, NO₂, NMHCs and TVOCs in university campuses. Additional ventilation and frequent monitoring of air quality in these departments are recommended.

摘要

空气污染与几种有害的健康状况有关。本研究评估了一所大学自然科学系的舒适度参数、优先空气污染物、硫化氢 (H ₂ S)、非甲烷碳氢化合物 (NMHC) 和挥发性有机化合物 (VOC)，以了解它们在大学空气污染物浓度中的作用环境和相关的健康风险。各部门的空气污染物水平参差不齐。所有部门都存在高 CO _{2浓度，在生物化学、微生物学和生物技术 (BMBT) 部门观察到的 NMHC 和 VOC 水平最高。NO 2}的最高空气质量指数值为 111.3在BMBT部门。与接触这些污染物相关的健康风险在生理学上最高，其次是生物多样性，最后是 BMBT 部门。自然科学系似乎在大学校园中贡献了大量的 H ₂ S、NO ₂、NMHC 和 TVOC。建议在这些部门增加通风并经常监测空气质量。
