“Thus, non-smokers can be exposed to highly carcinogenic TSNA.”

NNN = 0 to 23 picograms per liter

NNK = 0 to 29 picograms per liter

1 cubic meter = 1,000 liters

1 nanogram(NG) = 1,000 picograms

Thus, NNN of 0 to 23 picograms per liter is the same as 0 to 23 nanograms(ng) per cubic meter

NNK of 0 to 29 picograms per liter is the same as 0 to 29 nanograms(ng) per cubic meter.
