- PI- – Cytotoxicity derived from live-cell imaging
- WST1 – Cytotoxicity derived from the WST1 method
- ED50 – Modeled deposited dose causing 50% of reported cytotoxicity compared to untreated controls
- Potency ED50p/ED50CNT – Relative deposited dose causing 50% of cytotoxicity among pristine incinerated thermoplastic (ED50p) compared to CNT-containing analog (ED50CNT) at the same time point. Potency comparisons across time points were not made
- N.D. Potency ED50p/ED50CNT value could not be determined as ED50 value for one or both groups exceeded highest concentration tested. None of the filtered preparations caused significant cytotoxicity in pSAECs
