...Compounds which interfere with test:
Silicate if present at concentrations greater than 350umol/L (about 32ppm) and/or if left standing for more than 5 minutes

Arsenate, but unlikely at natural concentrations

Hydrogen sulphide, if greater than 60umol/L (about 2ppm), requires anoxic conditions.

NO3 if around or greater than 124ppm, but you've got bigger problems then!

Also, high copper content (more than 160umol/L, about 10ppm) will reduce the colour....

h.c., do these compounds interfere with all tests or just those listed above respectively?

I have the Aquarium Pharmaceuticals Freshwater Master Test Kit, plus a few others, and I do have to admit I've burned my fingers a time or two with the acids in the kits. It wasn't serious either time, but I did wash my fingers well with cool water once I realized what was going on, and everything was ok.
