The permissible exposure limit (PEL) in the United States is 50 ppm (35 mg/m 3), while the IDLH concentration is estimated at 300 ppm. Repeated exposure to ammonia lowers the sensitivity to the smell of the gas: normally the odour is detectable at concentrations of less than 50 ppm, but desensitised individuals may not detect it even at ...

Freshwaters tend to have a wide range of pH values from 6.5 to 9. [25] Freshwaters that have a higher pH would be more sensitive to increases in ammonia due to the balance between ammonia and ammonium and the aquatic life would be more affected. The ammonia causes stress on the fish and damages internal organs which will eventually lead to ...

First of all, the max resistance jumps to 250 (from 200) —that’s less relevant for me, but it does permit a wider range of more expert weight lifters to consistently use the Tonal.
Hyperammonemia, or high ammonia levels, is a metabolic disturbance characterised by an excess of ammonia in the blood. Severe hyperammonemia is a dangerous condition that may lead to brain injury and death. It may be primary or secondary. Ammonia is a substance that contains nitrogen. It is a product of the catabolism of protein.
