Indoor air quality (IAQ) has gained significant importance by affecting health and occupational safety with the increase in time spent in indoor environments. In this study, IAQ at Çanakkale Onsekiz Mart University Biga Vocational School was evaluated and air pollutants such as particulate matter (PM), total volatile organic compounds (TVOC) and formaldehyde (HCHO) were examined in various indoor areas such as classrooms, canteen, corridors, laboratories and conference hall. Measurements were carried out using PCE RCM 15 Air Quality Measurement Instrument over multiple periods. The results show that PM concentrations were generally within acceptable limits but increased with student density and long-term occupancy. The intermittent exceedance of recommended TVOC thresholds underscores the necessity for enhanced ventilation strategies, particularly during periods of peak occupancy. HCHO levels remained low, indicating appropriate material selection in building construction and furnishing. The study emphasizes the necessity of periodic monitoring, optimized ventilation and awareness programs to improve indoor air quality and provide a healthier learning environment. Additionally, indoor temperature and humidity values were also measured and evaluated. The measurement results are thoroughly analyzed in the final section.

The future of phytomedicine in Southeast Asia (SEA) appears promising due to the region’s diverse tropical flora, which includes nearly 50,000 known medicinal plants. This review examines current trends in medicinal plant research, the incorporation of phytomedicine into modern healthcare systems, existing challenges, and potential solutions. Recent research has highlighted the therapeutic potential of several notable SEA medicinal plants. Moreover, some countries in the SEA, such as Thailand and Vietnam, have effectively integrated traditional medicine into their modern healthcare systems. By 2026, the herbal medicine market is expected to reach USD 104.78 billion, with Southeast Asia (SEA) playing a significant role in this global economic expansion. However, conservation challenges, methodological complexities, and strict regulatory requirements hinder the practices of phytomedicine. This review emphasizes the importance of international collaboration, technological innovation, and the implementation of sustainable policies in overcoming these challenges. Therefore, phytomedicine has the potential to enhance the global economy, drive healthcare innovation, and promote sustainability by addressing key challenges and harnessing the region’s abundant biodiversity
