Memo: ammonia toxicity

Applicant's summary and conclusion

Conclusions:
In most biological fluids ammonia exists in two forms and the toxicity is determined primarily by the pH of the solution. Since toxicity depends on the ammonia which enters the organism, and thence the cell, it is of particular importance that cell membranes are relatively impermeable to one form (ionized ammonia), whereas the other (un-ionized ammonia) passes tissue barriers with ease.
