Cell viability following exposure to 1R6F and RRP AqEs. Intracellular ATP levels measured by CellTiter-Glo immediately after 2 hrs exposure to 25% AqE of each test product (a) or after 2 hrs exposure and 48 hrs recovery (b) are presented as % relative to untreated cells. Relative ATP levels for each product AqEs are mean ± standard deviation from 3 independent replicates. **p<0.01, ***p<0.001.
