Health concerns related to particulate matter (PM) pollution are on the rise globally. This study investigates the effects of the main components of PM on human airway epithelial cells (Calu-3), focusing on three distinct types: PM10-bound PAHs (including Benzo[a]anthracene and Benzo[b]fluoranthene), PM10-bound trace elements (containing arsenic and lead), and PM2.5-bound ions (comprising sodium and calcium). Calu-3 cells were exposed to these PM components at concentrations ranging from 2 to 100 μg/mL. Unexposed Calu-3 cells exhibited a 60% increase in metabolic activity after 12 hours. In contrast, exposure to PM components resulted in significant reductions in cell viability, with PM10-bound PAHs and PM10-bound trace elements causing decreases of 54% and 55% respectively, and PM2.5-bound ions leading to a 63% reduction at 100 μg/mL. Additionally, there was found to be a notable rise in the expression of proinflammatory cytokines IL-8 and TNF-α. Specifically, IL-8 levels increased by 456%, and TNF-α levels rose by 660% after 12 hours of exposure to PM2.5-bound ions. These findings indicate that the size and composition of fine dust particles play a critical role in their cytotoxic effects, contributing to increased cell death, membrane damage, and necrosis in airway epithelial cells.
