Acute in vitro cytotoxicity assessment of insulation (top row) and coating (bottom row) LCPM2.5 during various lifecycle scenarios in human lung epithelial cells (Calu-3) at 2 doses of 20 and 75 µg/mL: (A, D) LDH release at 24 h; (B, E) metabolic activity at 24 h; (C, F) ROS at 6 h. Statistical analysis was performed on an average of 6 samples (LDH and metabolic activity) oand 4 samples (ROS) for each condition; fold-changes >20% were deemed to be statistically significant.
