Abstract
This study investigates the relationship between indoor air flow and accumulation of polycyclic aromatic hydrocarbons (PAHs) using spider silk as a passive sample Through a combination of computational fluid dynamics (CFD) simulations and experimental data, research di a significant difference under effective spider silk in controlled indoor air quality (IAQ). The study reveals significant variations in PAH accumulation within spider webs across different indoor environments, with stagnant airflow areas exhibiting higher PAH concentrations. Specific locations, such as corners and ventilation outlets, show consistent trends in PAH accumulation, underscoring the importance of strategic spider web placement for effective passive sampling. The research also highlights intriguing disparities in silk production among spider species and selective accumulation of different PAHs. The findings contribute to a nuanced understanding of indoor environmental dynamics and bio-monitoring outcomes, emphasizing the utility of spider silk as a reflective bio-monitor for assessing IAQ. This study provides valuable insights for future research endeavors aiming to enhance our understanding of indoor environmental quality and optimize passive sampling strategies.
