Sorry, can't help on ref ranges (maybe try VIN if you have access), but may be able to help on the chemical maths.

My chemistry is a bit rusty, but for this you need to know the molecular weight of the substance (try Google).

PPM = mg/L (for liquids)

mol = g/molecular weight

mg = (mols x molecular weight)/0.001

so, plug in the mols (remembering to convert from micromols or nanomols to mols as appropriate) and molecular weight to get the mg.

Since all the units you are using are per Litre, the answer you get will be the PPM.

my apologies if I have made an error - its been a long time since I last did this.

I was going to suggest the wildlife information network. But I can't seem to get to the website at the moment.

Have you tried ISIS?
