LC50 (Inhalation): 7338 - 11590 ppm (rat, 1 hour); 2000 ppm (rat, 4 hours) LD50 (Oral): Not applicable. LD50 (Dermal): Not applicable. SKIN CORROSIVITY: Ammonia is corrosive to the skin. ADDITIONAL NOTES: Rats exposed continuously to 180 ppm Ammonia for 90 days did not show any abnormalities of organs or tissues. 2007-06-01 B ecause ammonia's toxic effects appear at levels significantly below those that are acutely lethal (0.09 to 3.35 ppm NH 3-N or 1.3 to 50 ppm total NH 4-N at pH 8.2), and because some organisms in a reef aquarium may be more sensitive than the few organisms that have been carefully studied, it is prudent to err on the side of caution when deciding what concentrations of ammonia to allow in a 4.

Higher concentrations are hardly detected by conventional detectors, the type of detector is chosen according to the sensitivity required (e.g. semiconductor, catalytic, electrochemical). The Permissible Exposure Limit for ammonia set by OSHA is 50 parts per million (ppm) averaged over an eight hour work day. This is the standard that must be met in every work place.

When you test for ammonia with your aquarium test kit, the reading you actually have is a combination of ammonium (NH 4+ or ionized ammonia) and ammonia (NH 3 or unionized ammonia) known as Total Ammonia Nitrogen (TAN). Ammonia is the toxic part of the TAN. Ammonium even at high Ammonia Results - AEGL Program.

It should be under 0.02 PPM fro free Ammonia. Most of my tanks are old a never need ammonia testing since it has been 0 for Ammonia and Nitrites for longer then I can remember. On older tanks you monitor nitrates instead.
