Thanks Jim. That is helpful. The evidence you cite would appear to support a "some toxic effects are believed to have thresholds under some circumstances,"...

I just can't resist jumping in on this discussion. Theoretical work by Lutz et al. and the work that I did with several colleagues on formaldehyde while at...
... P.P.S. The argument that thresholds exist "because Paracelsus said so" sounds to me like the argument "because God said so", but you are forgiven. By the...
