It is a very toxic substance to tissues and extremely soluble in water. Only one nitrogen atom is removed with it. A lot of water is needed for the excretion of ammonia, about 0.5 L of water is needed per 1 g of nitrogen to maintain ammonia levels in the excretory fluid below the level in body fluids to prevent toxicity.
‘Waste-clearing’ system observed in human brains for the first time. ... “Going back to the sink analogy, waste removal happens mostly at night during sleep, like we do our dishes at night ...
